The main advantage of TRK's Hydraulic Demolition Grapple is that it works without a stiff arm. When used with a quick coupler, it makes for fast changing between attachments. No more hammering pins, just hook up the hoses and you're ready to go! It also works with direct pin-on. The other huge advantage with the hydraulic grapple is it has a far greater range of motion which allows the operator to access material at virtually any angle. If 360 degree rotation is required, it can be built into the design. Used mostly for site clean-up, demolishing buildings, heavy rock handling and managing concrete chunks. These Grapples also work great in sorting, scrap and salvage applications.
