The outer end portion of the boom carrier a material handling device which iS operable to perform lifting, towing, recovery and other material handling operations in the mine. A pivot arrangement supports the boom assembly for lateral swinging movement on the front end of the mobile body. A pair of double-acting piston cylinder assemblies are mounted on the mobile body and are con- nected to the pivot arrangement for laterally swinging the boom assembly. The boom assembly is also connected to the pivot arrangement for upward and downward pivotal movement independent of the lateral swinging movement by operation of a lift cylinder. With this arrangement the boom assembly is axtensible and movable laterally and vertically to move the material handling device to safely and efficiently perform a variety of material handling operations conducted in an underground mine.
