Cat Center-Lock Pin Grabber CouplerThe solution is obvious: Over-Center TechnologyImproved Pin Grabber CouplerCenter-Lock Pin Grabber Coupler engages and disengages tools in a similar fashion to other pin grabber couplers. The difference withthis coupler is found in the patent pending locking mechanism inside the coupler.Cylinder walls are much thicker andthe diameter of the cylinder itselfis much larger — giving increasedclosing power and resistance toextreme forces.A highly visible Secondary Lockclearly shows an operator when thecoupler is locked on to the pin of abucket or work tool.Visibility gives confidence to maketool changes quickly and safely —saving time with every tool change.And, the Secondary Lock has thestrength to hold the full weight of abucket if a back pin is missed whenengaging the attachment.Hydraulic pressure pushes theCenter-Lock Rocker into place andkeeps the Secondary Lock securelylocked over the front bucket pin. Evenin the event of hydraulic failure thecoupler stays locked on to the pin.Counterbalance Valveand positively pressurizedhydraulics assure thecoupler is locked on to thework tool.Primary Hook graspsthe back bucket pinand tightly secures thework tool.Over-Center Technology: Once thelocking mechanism passes overcenter, the Secondary Lock is heldfirmly over the front bucket pin.
