Description

Bearing and braking device of monorail crane Technical Field The invention relates to the technical field of monorail cranes, in particular to a bearing and braking device of a monorail crane. Background The monorail crane locomotive is used as auxiliary transportation equipment for coal mines, has the advantages of high safety, large driving force, strong adaptability, small occupied space, high transportation efficiency and the like, is widely applied to narrow spaces such as roadways, mines and the like, and is auxiliary transportation equipment suitable for most coal mines in China. Monorail locomotives are typically powered by means of explosion-proof diesel engines or batteries, the locomotives being capable of moving along tracks suspended above a roadway or mine. The braking device of the monorail crane locomotive is generally combined with a driving unit to form a driving braking part, and has the dual functions of locomotive driving and braking.
