ABSTRACT:
An attachment, such as an operator's compartment or a mine roof drilling and bolting assembly is positioned adjacent the body portion of a self-propelled mine vehicle with the bottom portion of the attachment in slidable contact with the mine floor. In one embodiment a slide assembly for supporting the attachment for upward and downward movement relative to the mine vehicle is pivotally connected by a hinge assembly to the vehicle body. With this arrangement the attachment is operable to move upwardly and downwardly relative to the hinge assembly, which is fixed to the vehicle body. The attachment is operable to pivot about the hinge assembly as the bottom portion of the attachment slides along the undulating surface of the mine floor. In another embodiment the hinge assembly is secured to the attachment and supports guide rails of the slide assembly which are slidably received within a guide member secured to the vehicle body. With this arrangement the hinge assembly moves upwardly and downwardly with the attachment as the guide rails slide in the guide member. The attachment is also arranged by operation of a piston cylinder assembly to be tilted to a preselected position where only the front edge of the rear edge of the attachment bottom portion slides on the mine floor.
