Compared with general cranes, intelligent cranes have artificial intelligence, which replaces or assists human mental labor on the basis of replacing human physical labor. By integrating sensors with intelligent decision-making software and cranes, perception, analysis, reasoning, decision-making, and control are achieved Function, achieving interaction and integration between humans and objects, replacing manual perception, decision-making, and execution, enabling the crane to adapt to changes in the working environment. Its workflow is the same as that of a general crane, but the added intelligent control can replace human vision, hearing, and smell Sensory organs such as the senses and limbs replace the operator's judgment to make corresponding actions, completing recognition, perception, operation, and management during the operation of the crane.

Double-girder bridge crane is a commonly used bridge crane, used with electric trolleys. The performance parameters of the double-girder bridge crane include: lifting capacity, lifting height, span, mechanism working speed, working level, wheel pressure, etc. These parameters are explained in detail below:

A single-girder crane, as the name suggests, has only one beam. A double-girder crane generally refers to a double-girder bridge crane. A double-girder crane generally consists of three major parts: mechanical, electrical and metal structures.

The double-girder bridge crane has superior performance, compact structure, light weight, reliability and operation, and can meet various working conditions. It can reduce the overall investment in the factory, improve production efficiency, reduce maintenance costs, and save operating energy consumption.

Its main advantages: strong power, large traction, and strong climbing ability (can climb 25-degree slopes). The maximum load capacity at a 25-degree slope is 32 tons. At present, the diesel engine monorail crane can achieve 12 drives; the traction force of each drive is 25KN, and the maximum traction force reaches 300KN. Its main disadvantages are: the exhaust gas emitted by the diesel engine causes pollution to the narrow tunnel space, noise pollution, and complicated maintenance.

Maintenance of the diesel monorail crane is very important for the normal transportation of underground mining. Especially in some relatively large coal mines, the depth of the mine is large, the ground pressure is high, and the tunnel floor is seriously deformed.
