Description

Fixed large crane

Technical Field

The utility model relates to a fixed large-scale crane belongs to crane technical field.

Background

The crane is commonly known as a crane and is divided into the following parts according to the industrial and mining weight and the hoisting weight: truck crane, crawler crane and tyre crane, the three have advantage and shortcoming of self separately, specifically are:

the truck crane is commonly called as a truck-mounted crane, combines a truck and a crane, and can work directly without assembly in a self-propelled manner. The advantages are convenient and flexible, high working efficiency, fast transition and improved working efficiency; the defects are that the method is limited by terrain, large-scale equipment (1000-2000 KG) can not be completed, (the maximum tonnage of the truck-mounted crane is 20 tons).

The crawler crane is a crane which has a lower chassis which is a crawler walking mechanism and runs by a crawler. The lifting device has the advantages of large lifting capacity, capability of lifting and walking, and stronger lifting capability. The defects are that the disassembly and the assembly are troublesome, the crane boom can not freely stretch, the limitation is too strong, the crane boom is suitable for large-scale factories and works in factories, and the cost is huge.

The tire crane is a boom rotating crane which runs by using a tire type chassis. The tyre crane is a full rotary crane with a hoisting mechanism installed on a special chassis composed of heavy tyres and wheel shafts, and the upper structure of the full rotary crane is basically the same as that of a crawler crane. Truck cranes are also a type of tire cranes. The advantage is that the automobile body is short, and the operation is removed in a flexible way, and work efficiency is high. The disadvantages are limited by terrain, large-scale equipment can not be completed, and the cost is high.

Due to the limitation of use frequency and maintenance cost, most cranes, especially crawler cranes and tire cranes, are used by most owners in a renting mode, and in occasions with high use frequency, the renting cost even exceeds the value of the crane, so that the burden of the owners is further increased, and how to reduce the use cost of the crane is always the key point of research of technicians in the field.
