The Most Professional Manufacturer of Underground Construction EquipmentSunward started with independent research and development of hydraulic static pile driver. Through more than 10

years of engagement in underground construction, Sunward Intelligent has successfully developed the professional

underground works equipment series with the most complete categories and the highest geology adaptability and

become an enterprise that is able to provide comprehensive solutions (design, equipment and construction) for

underground works construction under complicated geological conditions. The Company has developed the powerful

multi-function drilling machine, pipe following drilling machine and rotary drilling machine that are unique in this

industry.

The first hydraulic static pile driver highly coupled with mechanism, electricity and hydraulics (winning the National

Second Prize in Terms of Scientific and Technological Progress) integrates various patented technologies and has

gained a market share as high as 60%. This product has been derived from the original one through innovation in

terms of construction method and theory and is regarded as a milestone in the application history of pre-cast

concrete pipe piles in the foundation industry of China.

Committed to The Field of Underground ConstructionSunward insists on technological innovation and constant improvement in development and construction of

underground construction equipment, and boasts the most complete construction equipment and construction

technologies suitable for underground works construction process in China in the aspects of foundation piles, even

wall, foundation treatment, new pile types and new technologies.

Sunward developed the rotary drilling machinery series products with the most complete specifications in China, with

power head output torque ranging from 40KN to 600KN.M and construction bore diameter ranging from 350MM to

3,500MM. Its theoretical system has formed the only two monographs in this professional industry, namely Research

and Design of Rotary Drilling Machine and Rotary Drilling Machine, Construction and Management.

The wide-range design is adopted for the parallelogram adjusting mechanism, with a large structural size (i.e. the size of M is large). The installation distance between the trolley traveling cylinders of the two drill masts (the size of M is large), which is equivalent to a triangle structure. This improves the s tab i l i ty o f the operat ion dev ice for construction on hard ground.

Luffing Structure

The box type square shaft casing structure is used for the mast deflection seat. The force of mast is directly transferred onto the trolley traveling mechanism, thus eliminating the stress of the rotary frilling force on weak links of the deflection seat and improving the structural stability and reliability.

Square-Shaft Casing Structure

The self-made special extendable chassis suitable for the actual load is adopted, which improves the stability of the complete machine. With this chassis, construction in any range of 360°can be implemented, and performance of the structural components of the complete machine can be improved, thus ensuring a balanced center of gravity.

Special Chassis

The main and auxiliary winches are installed on the platform, which greatly reduces the tipping torque of the operation device and the rotary inertia of the upper part of the platform and improves the stability of the complete machine.

It can effectively solve the problem of insufficiency of the rotating power and prevent the output shaft of the reducer from damage in rock entry construction.

Winch Arrangement

The high-strength anti-deformation design is adopted for the drill mast. The rectangular mast section is even wider in the guide rail direction. This can effectively reduce the structural stress of the mast and make it more suitable for the rock penetrating construction condit ions which involves high-strength variable and constant load.

Mast Structure

Slewing brake

The equipment is equipped with the patented elongated drive chain, to effectively resolve the problem of fracture and difficult repair of mounting bolts of the chain, and by coordinating with the drill pipe, it can extend the service life of the drill pipe by more than 10%. With the independent oiler lubricating reducer, it can reduce pollution and enhance the service life of the reducer. The multi-loop forced lubricating cooling system can strengthen the lubricating and heat dissipation effect, and lengthen the service life of the power head.With a multi-sealed structure, it can effectively prevent the sediments entering into the gear box and protect the seals from damage.Equipped with casing drive interface, the casing driver can be directly installed for the machine without any change.

Power Head

The drilling reactive force of the rotary drilling rig is transmitted from the drilling rig to the machine and then from the machine to the ground. Various structural components of the machine are subject to the structural stress resulting from the drilling force. Unique design is adopted for various structural components of the transmission chain on the rotary drilling rig of Sunward so as to guarantee a more stable structure and higher bearing capacity of the machine.
