Specalog for 525B Skidder - Kelly Tractor

Performance - HydraulicsState-of-the-art hydraulic system contributes to system efficiency and operational ease andproductivity.Load Sensing Hydraulics. A loadsensing variable displacement pumpand pressure compensating systemcontinually monitor hydraulic powerrequirements, and provide hydraulicpower based on demand.Less Hydraulic Pump Demand. Thehydraulic pump doesn't runcontinuously under load, but operatesonly when needed. This lowershorsepower consumption, maximizespower to the ground as well as loadingand grapple forces. It also increasesfuel efficiency, extends hydrauliccomponent life, and reduces systemheat.Auto-Grab Feature. Auto-Grabconstantly monitors tong pressure andadjusts as needed to securely holdgrapple loads. Like the load sensinghydraulic system, Auto-Grab placesdemand on engine horsepower onlywhen the system senses a shift in theload that requires a change in tongpressure. It is easily activated ondemand by a switch located on theright-hand control lever. Tractoroperation is easier, constant tongpressure is maintained, and operatingcosts are reduced through greater fuelefficiency and less time spent regrippingslipped loads.Winch. The 525B uses a high capacitywinch with four-function control. Thisself-contained unit has a separate oilpump using winch sump oil for control,and to cool and lubricate the winch.Cat Hoses. Caterpillar hose technologyallows high pressures for maximumpower and reduced downtime, andintelligent routing minimizes exposureto damage.Steering. Fully hydraulic control.Meets the following standards: SAEJ1511 OCT90, ISO 5010-1992.5
