Logging Grapple KM 634

KM 634
Logging Grapple
The KM 634 is a robust and powerful tool for logs – especially for heavy duty operation. Well
suited for handling single trunks.
lLow height with one horizontal hydraulic cylinder – especially when closed due to the interlocking arms.
lLong service life is ensured by the sturdy construction, high quality components and generously
dimensioned bearing system. All bearing bolts are case hardened and housed in steel bearing
bushes.
lOptimised design allows extremely small grapple diameter – ideal for handling thin timber securely. The arms open almost vertically. That enables an easy penetration into the timber stack.
lSynchronisation of arms due to sturdy compensation rods.
lProtection of the hoses for the hydraulic connections by a hose guard on the
KINSHOFER rotator.
l Precise positioning of the loads is no problem in combination with the
KINSHOFER rotator – continuous rotation, precise start and stop ability.
lSafety is assured in the event of an unexpected pressure drop due to the integrated
non-return valve.
lThe reinforced logging grapple KM 634S has an even more sturdy construction
and is equipped with a stronger rotator.
lEfficient handling with high closing forces (2860 lbf to 3520 lbf kN at an operating pressure
of 3480 psi).
