OPERATING PRINCIPLETheoperatingcyclestarts withtheliftingphaseof
theram(whichis an integratedramweight,rampointandpistonrod). ValveP
in thepressureline is openandvalveR in theretum line is closed.
Whenthepresetstrokeis reached,valveP is closedandR
opened,allowingthe ram to start its downwardstroke. Theramis
acceleratedby a pressurizedgas bufferabove themain piston, giving
theraman accelerationof upto 2g.Thisreducesthe actual
strokeandincreasesthe blowrateof thehammers.After impact,
thecyclerepeats.
Theram is guidedbyoillubricated
upperandlowerbearings.Thiseliminateswearon the
ramoThehammercanworkat ali inclinations,evenhorizontally.
At impact,the ramstrikeseithera solidsteel anvil(for
steelpiles), or a helmet (forconcretepiles). Thehelmetcontainsa
hammercushionon topand a pilecushionat thebottom.
Thehammercan beoperatedleaderguided,or freehanging.In thelatter
case,the hammerisprovidedwitha pile sleevetogive it
sufficientstabilitywhendriving.
