Abstract of the Disclosure A system including a hitch adapted for pivotal connection to a boom or dipperstick and including a downwardly projecting hook, and co- operating structure secured to a materials handler and having a cross-member for engaging the hook. A bearing plate secured to the body of the hitch above the hook defines a downwardly-facing bearing surface and engages an upwardly-facing bearing surface secured to the materials handler cooperating structure. In one embodiment, the hitch and materials handler are relatively rotatable about a pin assembly which both connects the relatively rotatable hitch portions and forms the hydraulic cylinder carrying a piston controlling a locking pin.
