Hoisting machinery is a device that can move up and down and lateral loads to help lift materials. It is widely used in various workshops.Because the space of the factory is relatively narrow and the structure of the factory's own beam can be used as the tripod of the crane, the practical plant cranes are generally bridge cranes, gantry cranes and electric hoists.These lifting equipment are ideal for use in plant lifting operations.
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 material lifting. 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 field 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.
Electric hoist is the simplest lifting equipment. It can be used alone or in combination with gantry 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.
