ABSTRACT:
A system for attaching a material handling tool to an arm of an excavating device includes a forward hook for engaging with a pin on the material handling tool and a rearward latch mechanism for engaging with a rearward fixture on the material handling tool. The rearward latch mechanism uses a rotating pin to lock the latch mechanism. By uniformly spacing the latch mechanism from the forward hook, and by also including a second latch mechanism, spaced from the rearward latch mechanism, a versatile standardized attachment device is created.
