Detachable cab construction for mining machines

摘要

A mining machine is provided which incorporates a detachable cab construction. The mining machine includes a clamping mechanism including a pair of a clamping hook assemblies for releasably clamping the cab body, and a lift cylinder for raising and lowering the cab body. In operation, the cab is detached from the mining machine in a safe area and the mining machine trammed into a mining position. The cab is equipped with remote controls so that operation of the mining machine can be controlled from the cab while the latter is located in a safe area. A safety interlock system prevents operation of local machine-mounted controls until the cab is re-mounted on the mining machine.
