Technical Field

[0002] The explosion-proof diesel engine monorail crane is a kind of lifting equipment widely used in dangerous environments, mainly suitable for production sites in industries such as petroleum, chemical industry, and coal mining. It can perform lifting and transportation work in dangerous environments, and also has the function of personnel transportation.

[0003] At present, the explosion-proof diesel engine monorail crane locomotives used in coal mines often have a cab (usually two), and the driver needs to sit in the cab and control the forward, backward, lifting and transportation operations of the explosion-proof diesel engine monorail crane locomotive through the operating handle. During the lifting and transportation operation, at least one person is required to cooperate with the driver to ensure safety. However, if the number of staff is insufficient, the driver has to perform more tasks, including going back and forth between the cab and the lifting of materials, which increases the driver's workload and work intensity.

[0004] In addition, explosion-proof diesel engine monorail cranes sometimes encounter inclined lanes during work. If they encounter inclined lanes, some dangerous situations are likely to occur, such as monorail cranes losing control, or even running away. These accidents not only affect the progress of work, but also easily cause accidents and injuries to the driver in the cab. Utility Model Content
