An improved material handling apparatus includes an adapter assembly which is disposed on the outer end portion of a boom. The adapter assembly is connected with a material handling tool by an improved connector assembly. The connector assembly includes a wedge member having a pair of sloping side surfaces which cooperate with a wedge surface on the material handling tool and a wedge surface on the adapter assembly to interconnect the adapter assembly and the material handling tool. The wedge member cooperates with the wedge surfaces on the material handling tool and the adapter assembly in such a manner as to positively seat a support bar on the material handling tool in a recess on the adapter assembly. In addition, the interaction between the wedge member and the two wedge surfaces is such as to compensate for wear between the wedge member and the wedge surfaces and to compensate for slight misalignments between the adapter assembly and the material handling tool.
