ABSTRACT:
A longitudinally extending conveyor discharge section is connected for horizontal and vertical pivotal movement on a frame of a mining machine. A pair of service shoes is connected at one end to the machine frame below the conveyor support frame for pivotal movement into and out of contact with the mine floor. A pair of double acting piston cylinder assemblies is connected at opposite ends to the conveyor discharge section and the service shoes. The conveyor discharge section and the service shoes are removably pinned to the machine frame. The pins for the conveyor discharge section are removed when it is desired to elevate the conveyor by actuation of the cylinder assemblies in a first mode. To perform maintenance operations on the mining machines, the machine frame is elevated by lowering the service shoes to engage the mine floor. The conveyor is lowered and pinned to the frame. The service shoes are then released from their pinned connection to the frame to actuate the cylinder assemblies in a second mode to lower the shoes into contact with the mine floor and elevate the end of the machine frame. With this arrangement a single set of piston cylinder assemblies located at the rearward end of the mining machine frame control movement of both the conveyor discharge section and the service shoes.
