Answers to the problems of gantry cranes and fuselage cracks in Henan KuangShan

As a large lifting equipment, gantry cranes undertake heavy material transportation. It is one of the indispensable equipments in engineering and construction industry. Gantry cranes are such important equipment. The following are answers to the problems of gantry cranes and fuselage cracks in Henan KuangShan.

First, the type of gantry crane 

A brief description of the four types of gantry cranes

1. Semi-gantry crane: The legs have unevenness and can be determined according to the civil construction needs of the application site. Features: The legs have unevenness, which can be determined according to the civil construction needs of the application site.

2. Full gantry crane: The main beam has no overhang and the trolley is carried out within the main span. Features: The main beam has no overhang, and the trolley is carried out within the main span.

3. Double cantilever gantry cranes: One of the most common planning methods, the planning of the force and the useful use of the site area are fair. Characteristics: The most common planning method, the planning of the force and the useful use of the site area are reasonable.  

4. single cantilever gantry crane: this planning method is often chosen because of the constraints of premises. Characteristics: this planning method is often chosen because of the bondage of premises.

Second, the hoist crane fuselage crack problem answer

What is the cause of the crack in the crane body? The Henan KuangShan analyzed the following reasons: 

1, the impact of wind. Semi-gantry cranes are likely to operate in the open air, all day long in the sun and rain, coupled with the role of wind force makes the bridge crane in the process of the inevitable wind blockade. Once the wind is too strong, the crane will withstand the wind while operating, the load will be increased, beyond the mechanical capacity, and then consolidation of the machine will have a moment of shaking, once overloaded machine body may appear cracks and cracks.

2. The appearance of cracks may be due to the lack of forward-looking design in the manufacturing process, and the failure to take into account the mechanical consolidation and durability also needs to be prevented. The reinforcement of the crane can reduce the damage degree of the main girder of the bridge crane.

3. Improper installation of gantry cranes will cause corrosion and damage of growth time. Therefore, in the time of installation and normal inspection should also be paid attention to, the importance of mechanical maintenance can not be lacking. Because the gantry crane will be corroded to varying degrees under long-term use, if the impact force is added, the crack will appear. So when inspecting, we should pay attention to adding lubricating oil to reduce friction and postpone the service life of the crane.
