TITLE MULTI-PURPOSE MATERIAL HANDLING MACHINE FOR USE IN A MINE ABSTRACT OF THE DISCLOSURE A self-propelled vehicle maneuverable in an under- ground mine includes a low profile mobile body with a forwardly extending boom. Piston cylinder assemblies extending between the boom and the mobile body are operable to both laterally and vertically pivot the boom relative to the mobile body. bracket extends forwardly from the outer end of the boom. The bracket is releasably engagable with a bracket receiver of a multi-purpose bucket by a pair of quick release pins. The bucket includes a movable portion connected by a pivot mech- anism to a carrier portion. Piston cylinder assemblies extending between the movable and carrier portions are operable to generate pivotal movement of the movable portion toward and away from the carrier portion to locate the movable portion in a preselected operating position relative to the carrier portion for conducting selected material handling operations. With the bucket movable portion in a fully retracted position within the bucket carrier portion, the bucket is operable to carry out bulldozing and loading operations in a mine. The contents of a loaded bucket are discharged by actuating the piston cylinder assemblies to pivot the bucket movable portion forwardly away from the bucket carrier portion. The bucket is also operable as a clamshell. The versatility of the vehicle is enhanced by the ability to efficiently replace the multi- purpose bucket on the end of the boom with another material handling device. -2-
