Abstract:
An operator's safety cab for an underground continuous miner for coal and the like has a cage constructed of triangular-shaped tubing to provide for torsional rigidity and a shearing edge for material falling on the cab from roof or wall cave-ins. The cab has a canopy with a plurality of angled surfaces and a frontal angled screened section for deflection of falling material and protection from crushing material. The cab also has a cab door supported by the edges of the cab and has six support standards of triangular cross-section to support the canopy and frontal section. The sides and door of the cab are screened with heavy mesh screens to further protect the operator.
