Practical plant cranes are generally bridge cranes, gantry cranes and electric hoists, etc. These lifting equipments are ideal for use in plant lifting operations. Because the space of the factory is narrow and the structure of the factory's own beam can be used as the tripod of the crane.
The bridge crane can traverse the lifting machinery above the workshop and can carry out load operation in the horizontal, vertical and horizontal directions to carry out the lifting of the materials. The overhead crane is also called a crane because its two ends are placed on the concrete beam or the metal beam of the factory building, and the whole machine is in midair.
The longitudinal rails are installed at both ends of the bridge crane to enable the crane to move longitudinally, so that the space under the bridge can be better utilized to lift heavy objects and avoid obstacles on the ground. Bridge cranes are the most widely used and largest lifting equipment on the market.
The gantry crane is improved on the basis of the bridge crane, and can be used in the material yard outside the factory to carry out loading and unloading of the cargo. The metal structure of the crane is similar to the door frame, and has a leg at each end of the main beam, which can perform load movement on the track on the ground, and the two ends of the main beam also have the function of extending the cantilever beam. Because of the advantages of site utilization, large operating radius and good versatility of gantry cranes, it has been widely used in some ports and factories.
This is the simplest lifting equipment. It can be used alone or in combination with doors and bridge cranes. It has the advantages of small size, light weight and use. It is common in industrial and mining enterprises, factory materials and other places.
