Monorail crane

Introduction to Monorail Crane

Monorail crane is an auxiliary transportation equipment with strong mobility, fast operating speed, large load capacity, and safe and reliable operation in suspended monorail systems. It is mainly used for installation and retraction of coal mine comprehensive mining working faces. Electric traction monorail crane is an auxiliary transportation equipment that uses batteries to provide power for locomotives. It has the characteristics of low system operating noise, low failure rate, easy maintenance, low price, and strong climbing ability. It can realize the overall transportation of large equipment such as hydraulic supports. At present, in domestic coal mine auxiliary transportation, there are mainly explosion-proof battery monorail cranes and diesel engine monorail cranes.

Characteristics of monorail crane

1. The cable only needs to be laid once, and the forward and backward movement of the cable only requires the operation of the handle, which is convenient and flexible, greatly reducing the labor intensity of workers.

Not only can cables be hung, but also emulsion high-pressure rubber hoses and water pipes can be hung, and the liquid pipes and cables can be hung in layers; The pipeline layout in the tunnel is not only neat and beautiful, but also avoids the interference of high-pressure rubber hose vibration on cables.

3. The hydraulic working medium provides a power source (emulsion) for the fully mechanized mining face, which is not only convenient and safe, but also explosion-proof and flame-retardant.

4. Equipped with a locking device, it provides safety protection in the event of failure of the stepping mechanism braking device or when the inclination angle of the tunnel is large, ensuring the safety of the cable trailer monorail crane.

5. Innovative design, simple operation, safe and reliable.

Single track suspension function

Monorail crane is a specialized transportation device used for hanging and moving cables, emulsion high-pressure rubber hoses, and water pipes along the trench of coal mine fully mechanized mining face. Under the roof of one side of the transportation roadway in the fully mechanized mining face, anchor rods and chains are used to suspend the suspended track. The towing vehicle hangs all cables, high-pressure rubber hoses, and water pipes on top of it. The emulsion pump station on the working face is used as the power source, and the hydraulic step-by-step push-pull device composed of oil cylinders and connecting rods is used to suspend and move the cables, high-pressure rubber hoses, and water pipes along the roadway. This device avoids the disorderly placement of underground cables, reduces the space occupied by cables and the number of cable movements, avoids manual dragging of cables, and greatly reduces the labor intensity and work efficiency of workers.
