Monorail crane: The monorail crane is a system that uses a special I-beam hung above the roadway as a track, which is connected to a train group by hanging vehicles with various functions, and is pulled by traction equipment to run along the track. The traction power can be provided by wire rope, diesel engine, battery or pneumatic device.

The main advantages of monorail crane transportation: one is that the section of the monorail crane is small, and the utilization rate of the roadway section space is high; the other is that it can be used for continuous non-reload transportation in flat and inclined lanes, and its transport load is not limited by the floor conditions. A kind of vertical curve, horizontal curve and complex curve operation; third, it can complete auxiliary transportation from the mining area depot to the working face without reloading, and can be used for auxiliary transportation operations that connect the main transportation roadway and the mining area roadway. 

This machine drives the monorail crane to run flexibly. One machine can be directly transported by multiple forks and branches. It has low running resistance, high efficiency, few people, and can directly enter the working surface; fourth is automatic lifting, convenient loading and unloading, and low labor intensity; fifth is complete protection , Reliable braking; Sixth, ** and lower maintenance costs. Use diesel engine or electric motor for traction, good flexibility, unlimited transportation distance, can transport personnel, materials and equipment to any place where needed, strong climbing ability, maximum inclination of diesel locomotives up to 30°, battery locomotives up to 15 °. 

Disadvantages of monorail crane transportation: a reliable hanging rail suspension bearing device is required. The exhaust gas discharged by a diesel monorail crane has a small amount of pollution and peculiar smell. It is necessary to strengthen the ventilation of the transportation lane; because the running track is fixed by the suspension method, the monorail crane is running. The body is swaying and the transportation of overweight equipment is restricted.
