An Introduction To Cranes

Crane refers to the vertical lifting and horizontal carrying heavy objects in a certain range of multi-action lifting machinery.

Tyre crane's main features are: its driving cab and lifting control room 2 for one, is composed of crawler crane, crawler crane) evolution, the walking mechanism of walking tracks and bracket part into the chassis of the tire, overcome the crawler crane, crawler crane crawler threatening the shortcomings of pavement damage, belongs to the material handling machinery.

The bridge crane is a lifting equipment for lifting materials over the workshop, warehouse and yard. It is shaped like a bridge because its ends sit on tall concrete columns or metal supports. The bridge of the bridge crane runs longitudinally along the track laid on both sides of the viadas, which can make full use of the space under the bridge to lift materials, and is not hindered by the ground equipment. It is the most widely used, the most number of a kind of lifting machinery.

Some of the work of lifting equipment is characterized by intermittent movement, that is, in a working cycle of taking material, migration, unloading and other actions of the corresponding mechanism is alternating work, crane in the market development and use more and more widely. Due to the use of leg lifting and lifting weight driving often appear some accidents, the driving speed is also faster than the crawler crane (crawler crane); Stable operation, large lifting weight, can be lifted in a specific range of heavy walking, but must ensure that the road is smooth and solid, tire pressure meets the requirements, lifting off the ground shall not exceed 50CM; It is forbidden to walk long distances with loads. In order to ensure the safety of operation, lifting operation without legs is basically prohibited in China. Crane supporting the use of wire rope varieties including phosphating coating wire rope, galvanized wire rope and smooth wire rope.
