Crane machinery

A crane is a multi-action lifting machine that lifts and carries heavy objects vertically and horizontally within a certain range. Also known as crane, aerial crane, crane.

The main characteristics of the tire crane are: the driving cab and the lifting control room are combined into one, which is evolved from the crawler crane (crawler crane), and the crawler and walking support part of the walking mechanism are turned into the chassis with tires, which overcomes the shortcomings of the crawler crane (crawler crane) track plate causing damage to the road surface, and belongs to the material handling machinery.

The bridge crane is the lifting equipment for lifting materials over the workshop, warehouse and storage yard. It is shaped like a bridge because its two ends are perched on tall cement columns or metal supports. The bridge frame of the bridge crane runs longitudinally along the track laid on both sides of the elevated frame, which can make full use of the space below the bridge to lift materials without being hindered by ground equipment. It is a kind of lifting machinery with a wide range and a large number of uses.

Some of the work characteristics of lifting equipment is to do 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 absence of leg lifting and heavy lifting often occur some accidents, the speed of travel is also faster than the crawler crane (crawler crane); The operation is stable, the lifting weight is large, the lifting weight can be carried in a specific range, but it is necessary to ensure that the road is smooth and solid, the tire pressure meets the requirements, and the lifting shall not exceed 50CM from the ground; Long distance walking with load is prohibited. In order to ensure the safety of operation, it is basically prohibited to carry out lifting operations without supporting legs in China. Crane machinery equipment supporting the use of wire rope varieties including phosphating coated wire rope, galvanized wire rope and smooth wire rope.
