ABSTRACT:
A material handling platform is pivotally attached to the front of the material transport vehicle. Actuator means raise and lower the platform. The platform is arranged to tilt relative to the vehicle about a horizontal pivot at the front of the vehicle. A turntable is mounted on the platform. The material handling platform positions roof supports in an underground mine adjacent a long wall mining machine. The roof supports are transported by the material transport vehicle carrying the material handling platform with the longest dimension of the roof support aligned with the longitudinal axis of the vehicle. After the roof support reaches the position where it is to be installed, the roof support is turned relative to the vehicle by turning the turntable of the material handling platform so that the longest dimension of the roof support is at right angles to the longitudinal axis of the vehicle. The roof support is then removed from the vehicle by lowering and tilting the platform relative to the vehicle.
