Working Principle Of Truck Crane

Publication Date: 2024-03-27 Promulgator:Admin Clicks:1 Back

The driving cab and lifting control room of the truck crane are set up separately. The advantages of the truck crane are good maneuverability and rapid transfer. The disadvantage is that it requires outriggers when working, cannot travel under load, and is not suitable for working on soft or muddy sites. Mainly used in engineering construction, such as highways, bridges, buildings, emergency rescue, etc. During the construction of the truck crane, steel pads need to be laid under the legs of the truck crane to disperse the load and ensure the stability of the truck crane's station; during regular operations, the truck crane often needs to move, and every time it moves, it must Refold the leg pads and move them to the designated location for use.

There is a rotating drum underneath the boom, with a wire rope wound around it. The wire rope passes through the pulley on the top of the next boom to pull out the previous boom, and so on. When retracting, the drum is reversed to recover the wire rope, and the boom is retracted under its own weight. This rotating drum is driven by a hydraulic motor, so you can see two oil pipes, but do not mistake them for oil cylinders. In addition, there are some truck cranes with set-type plunger cylinders installed in the telescopic arms, but this application is extremely rare. Because the multi-stage plunger cylinder is expensive, and the boom will elastically bend when it is loaded, which has a great impact on the life of the cylinder.
