PRE-ERECTION INFORMATION

1. INSTALLATION PLANNING Elevators of this type should be preplanned to meet the job requirements. If so, engineering installation drawings have been made which will simplify the installation. These drawings should reflect the following considerations.

2. STRUCTURAL CAPACITY Safety is the first consideration in all planning for installation and operation of the elevator. This elevator has been designed to safely support its own weight and withstand winds to 100mph to the height specified. It is not designed to support or brace other equipment. ALL DISTRIBUTORS, CLEANERS AND/OR SPOUTING MUST BE APPROVED IN WRITING BY CHIEF AGRI/INDUSTRIAL WHEN INTENDING TO USE THE ELEVATOR FOR EITHER FULL OR PARTIAL SUPPORT OR BRACING. OTHERWISE, EXTRA ATTACHMENTS MUST BE INDEPENDENTLY SUPPORTED AND BRACED.

3. ELEVATOR LOCATION The elevator must be properly located to receive incoming material and discharge it at the desired location. This requires an exact location for the elevator boot unit. Determine whether the boot is to be fed from the down or the up leg side or both sides of the elevator. The down leg side is recommended for light materials like ground feed. The up leg side is recommended for heavier, free flowing materials like whole grains. On outside installations, check the planned location for the boot, head, spouting, and guy cables for

clearance to other structures. Driveways, overhead power lines and building structures can present special hazards and obstructions.

On inside installations, check the location for the leg as it passes through each floor. Additional clearance for the ladder must be provided.

4. BOOT FOOTING AND PIT Sufficient footings must be provided to adequately support the weight of the elevator and cable reaction loads in high winds. See Table 1 below for Footing Loads required per model and height elevators. Consult a local structural engineer for a properly designed boot footing. If the boot is installed in a pit or other permanent structure then adequate clearance must be provided to service the elevator. Adequate clearance must also be provided for removal of the boot pulley and the use of cleanout door. On outdoor installations the pit will require a sump pump or drain.

Table 1 - Bucket Elevator Footing Loads (lbs.) Includes weights and cable reactions for 100mph winds


5. GUY CABLES AND ANCHORS The leg must be braced every 20 ft. between the head section and the top of the boot unit. Guy cables are generally used for bracing above ground level. For legs extending into pits (below ground level) bracing near ground level is recommended, to obtain maximum overhead guy cable clearance.

IMPORTANT: CARE SHOULD BE GIVEN TO PROTECT GUY CABLES FROM ACCIDENTAL DAMAGE. TRUCKS OR FARM MACHINERY COULD CAUSE SERIOUS DAMAGE TO A CABLE AND RESULT IN THE ELEVATOR TO COLLAPSE.

Some protection is gained by guard fences and elevated anchors. Guard fences will keep equipment a safe distance from the cables. Elevated anchors will help vehicles to pass under the cables near the anchors. See Figure 9 below for a typical elevated anchor.

Anchors are to be located 90 degrees apart around the elevator, and must be properly designed to withstand the cable loads. Anchor locations are shown in Figure 10 and loads are charted in Table 2 (see page 27). All anchors must be designed by a Structural Engineer to match soil and ground conditions.

Figure 9 - Typical Elevated Anchor

Figure 10 - Anchor Placement


Table 2 - Anchor Loads

IMPORTANT: ALL CABLES OR BRACES

ATTACHED TO BUILDINGS OR OTHER STRUCTURES

MUST BE APPROVED BY THE MANUFACTURER OF THE

STRUCTURE OR BY A STRUCTURAL ENGINEER.

ELEVATOR INSTALLATION

1. GENERAL The preferred method of elevator erection is to first set the boot on the footing. Second, with the use of a crane, assemble the head, drive, leg sections & any service accessories from the top down. The elevator can be completely assembled, including drives, platforms, ladders, & cables while working within about 10 of the ground if this method is used. Crane time can be reduced if about 30 of legging, ladders, and etc. are attached to the head horizontally on the ground and then up righted with the crane. The head assembly, motor drive, upper leg sections, platforms and ladders can be assembled horizontally on the ground before hoisting the assembly, (see assembly in Figure 16 page 30). Position the head assembly with the discharge hopper up and with enough clearance to attach the leg sections horizontally to it. Attach the 20-30 feet of legging in this position, then upright elevator. Additional leg section, ladders, and etc. are then added as the elevator is raised.

CAUTION: DO NOT ALLOW ANY PORTIONS OF THE ELEVATOR ASSEMBLY TO DRAG ON THE GROUND, OR IN ANY OTHER MANNER TO BECOME DAMAGED WHILE ERECTING ASSEMBLY.

2. SETTING THE BOOT Locate the boot on its foundation according to pre-planned requirements. Refer to Figures 12-13 & Table 3 for suggested method for anchoring the boot. The boot must be bolted into position prior to erecting the elevator to avoid accidental movement. Use lag bolts for Anchor Clip attachment. NOTE: The boot top flanges where the leg sections attach MUST be exactly level. Use a grouting cement under the boot base angles as needed to level boot. Be sure grouting cement is under the complete leveled surface of the boot base angles for proper boot support.

Figure 13 - Anchor Clip Table 3 - Anchor Bolt Locations (based on layout shown in Figure 12)

Figure 12 - Boot Anchor Locations (based on clip as shown in Figure 13)


ELEVATOR INSTALLATION (continued) 3. INLET HOPPER The Inlet Hopper location has been predetermined as described on page 25 (3). To locate the inlet hopper on the boot use the dimensions in Table 4 & Figure 14. NOTE: Never locate the inlet hopper lower than the given dimensions in Table 4. To do so will affect the elevator capacity. These dimensions are based on Chief Standard Inlets; consult the factory for other loading conditions.

ELEVATOR INSTALLATION (continued) 4. LEG SECTION ASSEMBLY

Bolted Flange Leg Sections will vary in assembled components depending upon models. Leg sections will consist of two body sections (see Figure 18) or of a body section and a lid panel (see Figure 19).

IMPORTANT: When attaching Leg Sections that consist of a body section and lid panel, these must be positioned with the lid panel located away from the center of the elevator. (See Figure 19)

Figure 19 - Bolted Flange Leg Section consisting of two body sections

Figure 20 - Bolted Flange Leg Section consisting of body

section and lid panel

The elevator height will determine if heavier gauged material leg sections are required at specific locations of your unit. Bolted Flange Leg Sections will be factory stamped, identifying the material gauge. This gauge will determine the placement of the leg section. When attaching Leg Sections that are heavier gauged, these must be positioned closest to the boot assembly (see Figure 17 page 30).


ELEVATOR INSTALLATION (continued) Caulking compound is provided to apply to the faces of the leg flanges prior to joining the leg sections together to seal the joints from dust and weather leaks. Use only 3/8 diameter, grade 5 bolts provided to join the leg sections. Accurately align the flanges on the leg sections before tightening bolts to the values indicated in Table 5. Place spacer angles between the lower ends of each pair of leg sections (see Figure 20). The spacers hold the sections parallel and help reduce flange stress while making the horizontal assembly.

Table 5 - Bolt Torques Figure 21 - Spacer Angles


ELEVATOR INSTALLATION (continued) EXPLOSION VENTED TRUNKINGS

Figure 22 - Explosion Vented Trunkings


ELEVATOR INSTALLATION (continued) 5. DRIVE ASSEMBLY Install Reducer Drive on elevator. The Reducer Drive is packaged separately and includes manufacturers complete instructions for installation. Follow these instructions for Reducer Drive installation.

WARNING: REDUCER DRIVES ARE SHIPPED WITHOUT LUBRICANT. DO NOT OPERATE THE ELEVATOR UNTIL THE REDUCER DRIVE HAS BEEN FILLED WITH AN APPROVED LUBRICANT AS NOTED IN THE MANUFACTURERS INSTRUCTIONS.

A Reducer Backstop is recommended on tall and large capacity elevators. The backstop prevents a loaded elevator from reversing direction when power is lost to the head pulley. If the Reducer Drive has been equipped with a backstop, then a check for correct direction of rotation is required. To do so rotate the top of the head pulley towards the discharge side of the head, see Figure 16 (page 30), the pulley should rotate freely in this direction but not in the opposite direction. If the backstop is reversed, refer to the reducer manufacturers instructions.

Position motor on the head assembly motor mount and attach with bolt package provided. Adjustment to the motor mount may be required so that the end of the motor shaft is in line with the end of the reducer input shaft. Tighten belts to specified tension according to V-Belt tension (page 34).

NOTE: All sheaves, sprockets, and drive components assembled at the manufacturer (including the bucket elevator pulley) should be checked for alignment, centered and tightened prior to operation and at regular operating intervals.

WARNING: EXPLOSION PROOF ELECTRICAL EQUIPMENT MUST BE USED WHENEVER AN ELEVATOR IS LOCATED IN AN EXPLOSIVE ATMOSPHERE. A SAFETY SWITCH SHOULD BE INSTALLED ON THE HEAD TO PREVENT ACCIDENTAL MOTOR OPERATION WHEN SERVICING THE HEAD.

WARNING: DO NOT OPERATE ELEVATOR WITHOUT BELT GUARD ASSEMBLY PROPERLY INSTALLED.

Figure 23 - Drive & Belt Guard Assembly


ELEVATOR INSTALLATION (continued) Install Belt Guard & Drive components (see Figure 21). Configurations and bracketing of Belt Guards differ per model of elevator and reducer drive. Refer to Supplemental Drive & Belt Guard Assembly Drawings shipped with drive package for installation instructions on your specific model. Install belt guard back panels and bracketing (some field drilling may be required for bracket attachment to back panels). Adjust belt guard bracketing to allow for back panel clearance away from motor & reducer. Install sheaves and belts allowing for clearance away from back panels. Complete installation by placing belt guard shell over the sheaves and belts and then attaching the shell to the back panels.

6. SHEAVE ALIGNMENT Check that sheaves on motor and reducer are aligned and level. Use straight edge that lies across the face of each sheave to check alignment as shown in Figure 22.

Figure 24 - Sheave Alignment

7. V-BELT TENSION Install the drive belts and adjust belt tension. Using Belt Tension Checker adjust the belts so that a force in the middle of each belt will deflect the belt 1/64 for each inch of distance between the sheave centers, as shown in Figure 23. The Deflection Force is shown in Table 6. Ideal tension is the lowest tension at which the belt will not slip under peak load conditions. Over tensioning shortens belt and bearing life. Check tension frequently during the first 24-48 hours of operation.

Figure 25 - Belt Span

NOTE: Compare the force you have applied with the values in Table 6. The force should be between the minimum and maximum shown. The maximum value shown is for New Belt, and new belts should be tensioned at this value to allow for expected tension loss. Used belts should be maintained at the minimum value as indicated in Table 6.



Table 6

Deflection Force

8. GUY CABLES The elevator must be guyed, or otherwise laterally supported every 20 feet from the top of the boot to the head section. At each 20 foot level, four cables must be attached in equal directions and attached to anchors previously planned & placed according to Pre-Erection Information (Guy Cables and Anchors page 26). Cables must be of sufficient strength, uniform elastic nature, & adequately tensioned to prevent the elevator from bending or whipping in wind storms.

Cables can be precut to length by following Table 7. This chart corresponds with Pre-Erection information (Figure 11 Anchor Locations, page 27). Anchor cables A, B, & C correspond with (Figure 11) A, B, & C anchor location.

Lengths of cable listed in Table 7 start with the highest cable at each anchor location and work down and also start at the brackets located just below the head section and continue down the elevator at 20 intervals.

NOTE: Cable lengths shown are straight line lengths. NO allowance in the cable length has been made for cable clamping, turn buckles, cable sag or any deviation in bracket or anchor locations. See Table 8 (page 37) for additional lengths required for clamping.

WARNING: All 3/8 diameter guy cables are to be 6,950 (lbs.) minimum strength (Siemens martin or equivalent) & all 1/2 diameter guy cables are to be 12,100 (lbs.) minimum strength (Siemens martin or equivalent). DO NOT mix types of cables even though they meet the minimum strength requirements.

WARNING: Guy Cables must not be attached by other means than those provided. Welding to or cutting into the leg sections is prohibited unless approved by Chief Manufacturing in writing.

WARNING: All cables or braces attached to buildings or other structures must be approved by the manufacturer of the structure or by a structural engineer.

WARNING: Care should be given to protect guy cables from accidental damage. Trucks or farm machinery could cause serious damage to a cable and result in the elevator collapsing.



Table 7 - Guy Cable Lengths

NOTE: All cables are 3/8 diameter except for lengths shown as xx*. This denotes 1/2 diameter cable must be used at this location.

The top sets of cables are attached to the work platform angle at the thimble locations. All other cable sets are attached to the Bolted Flanged Leg as shown in Figure 24 (legs consisting of two body sections) or as in Figure 25 (legs consisting of body & lid sections). Figure 26 illustrates 20X14 trunking (legs consisting of two body sections.) (All shown on page 36 and page 37)

Figure 27 - Guy wire bracket on Bolted Flange with two body section (Shown below is 16x10 & 16x14 trunking).

Figure 26 - Guy wire bracket on Bolted Flange Leg with body & lid sections (Shown below is 13x10 trunking).



Figure 28 - Guy wire bracket on Bolted Flange Leg with two body sections (Shown at left is 20X14 trunking).

The recommended method of connecting a cable is to bend the cable around the thimble for the specified cable turn back, see Table 8. Place the first cable clip 3 inches from the dead end. Place the second clip as close to the loop as possible, see Figure 26.

Figure 29 - Cable Clamp typical each cable connection

Table 8 - Cable Clamp Specifications typical each cable connection

To organize the attachment of cables while the elevator is being erected, pre-mark each guy wire bracket with its future position on the leg (height and direction), then determine the length of the cable for each guy wire bracket being sure to allow for all cable connections. Cut and attach the cables to predetermined guy wire brackets. As the elevator is assembled the guy wire brackets can be installed with the proper cables attached.

9. UPPER ASSEMBLY INSPECTION Make a final inspection of all parts on the upper 30ft. of the elevator prior to hoisting. A few points to check include:

a. Are all flange joints aligned properly and caulked? b. Are all bolts installed and properly torqued?

c. Have any damaged parts been used?


ELEVATOR INSTALLATION (continued) 10. HOISTING THE ELEVATOR In hoisting the elevator certain understanding and safety considerations must be made. These are best understood by an experienced erection crew. Always consider safety first.

a. The crane or hoisting equipment must have adequate lifting capacity and height to safely handle the load, see component weights Table 9.

b. The crane must be sitting on firm ground. c. Position the crane to allow the leg to be lowered onto the boot with clearance to attach all guy

cables. d. Weather conditions for the erection period must be favorable. e. Anchors must be installed and concrete cured prior to usage. f. Boot footings must be cured and boot upper flange leveled.

Table 9 - Component Hoisting Weights (lbs.)

Attach hoisting slings or chains to all eye bolts provided on the head section. Attach the slings so that the load is distributed evenly. Raise the upper elevator section into the vertical position with the crane.

CAUTION: DO NOT ALLOW ANY PORTIONS OF THE ELEVATOR ASSEMBLY TO DRAG ON THE GROUND, OR IN ANY OTHER WAY TO BECOME DAMAGED WHILE ERECTING ASSEMBLY.


ELEVATOR INSTALLATION (continued) Lift the assembly to a height sufficient to assemble the next section of legging, ladder, cables, & etc. Be certain to caulk leg flanges prior to assembly of leg sections. Torque all bolts according to Table 5 (page 32). Continue with assembly completing all leg sections, reststops, ladders, cables, & etc. The inspection section must be properly located on the up leg side, see Figure 8 (page 23) for stacking illustrations. The inspection door must be accessible from work floor area and located to the outside of the elevator.

IMPORTANT: KEEP ALL COMPONENTS INTACT DURING ASSEMBLY. ANY REMOVAL OF COMPONENT PARTS DURING ERECTION REDUCES ELEVATOR STRENGTH. DO NOT UNDER ANY CIRCUMSTANCES CUT INTO OR WELD ONTO THE LEGGING OR THE INSPECTION SECTION OF THE ELEVATOR. CUTTING OR WELDING CAN CAUSE STRUCTURAL DAMAGE. USE ONLY APPROVED LEG SECTIONS AND LEG BRACKETING.

11. SETTING AND GUYING THE ELEVATOR After completion of all legging inspection sections, lift the assembly over top of the boot. Before setting assembly on the boot, insure plumb between the head and boot sections. Use one or more transits to check the position. Caulk the flanges and set the assembly into position. Torque all bolts according to Table 5 (page 32).

Connect each guy cable to its anchor, starting with the lowest set of cables and progressing towards the top. Locate a turnbuckle on each cable at a convenient distance from the anchor. Extend the turnbuckles as far as possible to allow for later adjustment. Refer to Figure 26 and Table 8 for cable clamping information.

Use two transits to keep the leg straight and plumb while tightening the cables. Locate one transit in line with one row of anchors, and 50 feet additional from the farthest anchor. This transit will be used for adjusting cables extending to the right and left of it. Set a second transit 90 degrees from the first transit in line with the row of anchors, to adjust the cables extending in the other two directions (see Figure 27).

Figure 30 - Transit Locations


ELEVATOR INSTALLATION (continued) While plumbing the leg, tension all cables in alternate succession to 600-700 pounds. Starting at the lowest guy wire bracket location, tighten two cables in opposite corners of the elevator. Check leg for plumb, and then tighten the two remaining cables. Repeat this procedure for each successive guy wire bracket.

A final recheck for plumb is made with a plumb bob. If the leg is not perfectly plumb, one can experience difficulty with the belt not running true. Insert a plumb bob into the up leg section from the head section and lower it past the inspection door. Tie the plumb line to a cross board over the top of the head frame. Locate the line so it clears all sides inside the leg. Note the position of the plumb line with respect to the leg casing at the top and bottom ends of the elevator. If it is not the same within 1/2 inch, readjust the guy cables.

IMPORTANT: AFTER ALL CABLES HAVE BEEN TENSIONED AND THE LEG RECHECKED FOR PLUMB AND STRAIGHTNESS, PERMANENTLY SECURE THE TURNBUCKLES FROM LOOSENING.

NOTE: Either end or the center of a turnbuckle may turn and loosen the cable. One method of securing the cable is to lace a short length of cable through the ends and center of the turnbuckle and secure the cable with cable clamps. This also deters unauthorized persons from loosening the cables.

Chief Agri/Industrial (800) 359-7600 Belt and Buckle Installation - Page 44

BELT AND BUCKET INSTALLATION The belt and buckets are installed after the leg is erected, guyed and plumbed. The general procedure is to install the belt, make a temporary belt spice, install the buckets and then make the final splice.

1. BELT INSTALLATION Adjust the boot pulley into its highest position to allow maximum belt adjustment. Remove the clean out doors at the bottom of the boot. Remove the hoods on the head to expose the head pulley. Open the inspection section by removing the front door, screen and back cover.

IMPORTANT: CARE SHOULD BE TAKEN IN REMOVING INSPECTION SECTION PARTS. FORCES FROM AN IMPROPERLY PLUMBED LEG CAN CAUSE LEG TO COLLAPSE WHEN INSPECTION PANELS ARE REMOVED.

Therefore, loosen all bolts first to see if the covers are free of side loading on the bolts. If they are not free, do not remove the bolts until problem is corrected. Note: The screen and cover should never be removed during winds in excess of 20 MPH.

Several methods may be used to place the belt inside the elevator legs. Generally the belt is pulled with a rope or cable in through the inspection section opening, up and over the head pulley, down and around the boot pulley and back up to the inspection opening for splicing. The rope or cable used for this purpose must have sufficient strength to lift the belt to the head pulley.

With the head hoods removed, drop one end of the rope down the up leg and out the inspection opening. Drop the other end of the rope down the down leg, around the boot pulley and back up to the inspection opening. Removal of the cleanout doors will aid in feeding the rope around the boot pulley.

Attach the belt to the end of the rope coming down the up leg. Use a piece of angle to attach the rope to the belt. The angle should be the same width as the belt width with holes along one side to match the bucket holes and an eye bolt in the center of the other side for connecting the rope. Bolt the angle to the belt using the flat headed bolts provided for the buckets. It will be necessary to remove the motor drive belt to allow the upper head pulley to turn freely. Be careful that the belt does not run away when the belt in the down leg becomes longer than the belt in the up leg.

Figure 31 - Temporary Belt Space

2. TEMPORARY BELT SPLICE Make a temporary Lap Splice (see Figure 29) by overlapping the belt ends and inserting flat head bucket bolts through 3 or more sets of pre-punched bucket holes. The lap is made so that the trailing end of the belt is in contact with the pulleys and not the leading end. Lift the lower end of the belt to remove the excess slack from the belt. The flat head of the bolt is to run on the pulley side of the belt. Use flat washers under the nuts at this time.


BELT AND BUCKET INSTALLATION (continued) 3. BUCKET INSTALLATION Install the buckets by bolting them to the pre-punched holes in the belt (see Figure 30). Insert bolts from pulley side of belt and tighten nuts until bolt head is flush with belt. Tighten bolts to 10 ft-lbs of torque. Install buckets at intervals of 15 or more hole spacing to reduce unbalance on the belt. Continue adding another bucket to each interval on each round of the belt until all buckets are installed.

Figure 32 - Bucket Installation Figure 33 - Final Belt Splice

4. FINAL BELT SPLICE Allow the belt and buckets to hang for 24 hours or more to remove much of the initial belt stretch. The belt can then be re-spliced, tightened, adjusted and squared. With the boot pulley in its highest position, disconnect the temporary lap splice at the inspection door. Remove the excess slack from the belt and re-splice the belt. A five foot overlap is recommended on the lap splice (see Figure 31). Using the bucket bolts, match the overlapping pre-punched holes then bolt the belts together at the bucket hole locations. On pre-punched belt with holes spaced over 12 inches apart the spice must have 4 sets of bolt holes. Field drill extra sets of holes if required. Note: Recheck all bolts in the belt and buckets for proper tension. All bolt heads are to be snug with the belt surface. Replace clean out doors, inspection section back panel, screen door front panel, & head hoods.

5. BELT TENSION ADJUSTMENT Belt tension at the boot pulley must be maintained to eliminate belt slippage at the head pulley. Adjust boot pulley until slack is taken out of the belt. Then adjust the boot pulley down one more inch. Steering (centering) is accomplished by adjusting one side of the pulley tighter than the other. The belt will move to the slack side. If belt still slips, adjust the boot pulley down one more inch.


BELT AND BUCKET INSTALLATION (continued)

Figure 34 - Baffle Adjustment 6. DISCHARGE BAFFLE ADJUSTMENT A discharge baffle is located in the head discharge section to deflect material from the buckets, so minimum material returns down the leg (termed back legging). Adjust the baffle so it will clear the buckets by 1/8 (see Figure 32). NOTE: Buckets mounted on lapped belt splices will run closer to the baffle, final adjustments need to be made at this location.

Chief Agri/Industrial (800) 359-7600 Start Up & Operation - Page 48

START UP AND OPERATION

1. PRE-START UP INSPECTION Prior to operating the elevator, check all areas for safety issues and machine damage which could occur during operation. Follow all manufacturers pre-start up instructions for each individual component provided with your elevator.

IMPORTANT: DISCONNECT AND LOCK OUT ALL ELECTRICAL POWER

a. Is leg properly plumbed, with guy cables tensioned and secured from loosening? b. Check that head and boot pulley keys are in place. Check all set screws in drive sheaves,

head and boot shafts and pulleys, shaft bearings and gear reducers. c. Head pulley is level, centered, and squared in housing. d. Discharge baffle properly positioned and that discharge is cleared of obstructions. e. All hardware is in place and tight, motor, bearing bolts, and etc. f. Elevator belt spice is square and belt properly tensioned. g. Check that sheaves are properly aligned and V-belts properly tensioned. h. Bushing bolts in sheaves and reducer are torqued to manufacturer specifications. i. Drive guard and other safety devices are in place. j. All debris is removed from the elevator boot. Frequently recheck the boot for debris during

the first few days of operation. During construction debris can be left in other areas that feed to the bucket elevator, e.g. dump pit, bin unload conveyor, or the grain bin.

k. Head hood, boot cleanouts, and inspection section panels in place and properly secured. l. Reducer manufacturer specifications have been met. m. Reducer has Lubricant and is filled to proper level.

NOTE: Reducer has been shipped without oil.

ADDITIONAL SAFETY CHECKS:

Is there possibility of damage to leg or guy cables from vehicles? Is access to the electric controls and climbing ladder secure from unauthorized persons? Are pits designed to equipment to prevent personal injury? Is electrical equipment installed to meet national electric code and/ or local safety codes,

including explosion proof equipment where required?

CONNECT ELECTRICAL POWER: KEEP PERSONNEL AWAY FROM MOVING PARTS DURING INSPECTION.

2. START UP INSPECTION a. Operate the elevator empty under power for a period of time. b. Check that buckets are traveling in the correct direction. c. Check that the belt is running on center over the head and boot pulleys.

Chief Agri/Industrial (800) 359-7600 Start Up & Operation - Page 49

START UP AND OPERATION (continued)

3. FLOW SYSTEM COMPLETION To complete an elevator system, material feed and discharge connections must be made to the leg. Complete these connections before placing the leg into service.

4. ELEVATOR OPERATION Since the elevator has been previously operated without material, it may now be tested under load. It is suggested that the flow systems be checked next. Allow only a small amount of material to enter the elevator while it is running. Check that the material can flow through the system connections, valves, distributors, etc. This will check for proper functioning. Once all flow paths have been checked, the elevator may be loaded to capacity. Check elevator, once loaded to capacity for the following:

a. Back legging (grain being returned down the down leg).

b. Slippage of the head pulley.

c. Proper filling of buckets.

d. Electrical current (Amperage) draw on the motor.

An inspection of the elevator is suggested after the first 8-10 hours of operation. Inspection should include the following:

a. Check all bolts holding buckets to the belt for tightness.

b. Check that the belt is running in the center of the leg past the inspection section.

c. Check motor drive for looseness of pulleys, sprockets, belts, chains and torque arm.

d. Check for oil leakage or overheating of gear reducer.

e. Check head pulley hub bolts and set screws.

PERIODIC MAINTENANCE

Safe Operation of this Equipment Requires Proper Maintenance.

The following are guidelines for maintaining the elevator. Operators will have to determine what inspection and service intervals are necessary for their application. Factors to consider are the frequency of operation and the operating environment of the equipment.

IMPORTANT: DISCONNECT AND LOCK OUT ALL ELECTRICAL POWER PRIOR TO PERFORMING MAINTENANCE OR REPAIRS.

DAILY Always be aware of the normal operating sounds. If any sounds occur, stop the conveyor, find the

source of the noise, then lock out power to conveyor and repair the problem.

WEEKLY Lubricate bearings according to manufacturer specifications

IMPORTANT: DISCONNECT AND LOCK OUT ALL ELECTRICAL POWER PRIOR TO PERFORMING MAINTENANCE OR REPAIRS.

MONTHLY Check V-belt tension and overall condition. Replace if worn, frayed, or cracked. Check that set screws in pulleys and bearings are tight. If necessary tighten to manufacturers

specifications. Check for missing or damaged buckets. Replace if necessary. Check bucket bolts for tightness. Check that the elevator belt is properly tensioned and is running in the center of the leg. Check oil level in gearbox and inspect seals for signs of leakage. Follow manufacturers specifications for oil level and oil change periods. Check that the motor is clean and properly ventilated. Lubricate motor according to manufacturers specifications and intervals.

QUARTERLY Check guy cables, turnbuckles and cable clamps every 3 months for damage or loosening. Any

change in cable tension may cause the leg to go out of plumb, resulting in the belt not running on center and/or damage to the leg.

IMPORTANT: NEVER REMOVE OR LOOSEN ONE OR MORE CABLES WITHOUT PROVIDING OTHER MEANS OF SUPPORT TO THE LEG.
