There are many types of cranes, including gantry cranes, port cranes, marine cranes, bridge cranes, etc. Different cranes are selected in different occasions. The electric hoist has a compact structure, and the electric hoist with the motor axis perpendicular to the drum axis adopts a worm gear transmission device. Its disadvantages are: large length and width, bulky structure, low mechanical efficiency, difficult processing, etc. The hydraulic system is a two-layer control, and the overflow regulating valve and magnetic contact pressure gauge can control the pressure. The electrical control part adopts low-voltage control, which increases the safety of the control system. Crane refers to a multi-action lifting machinery that moves heavy objects vertically and horizontally within a certain range. It is also called overhead crane, aerial crane, and crane. The main parameters of the crane are the parameters that characterize the main technical performance indicators of the crane. They are the basis of crane design and the important basis of crane safety technical requirements. Cranes are important equipment for transfer and loading and unloading. With the development of science and technology and the progress of society, the innovative development trend of cranes is obvious.
The production and development of cranes is inseparable from the progress of science and technology. Combined with computer technology, it improves the efficiency of production, reduces errors in the production process, and can detect the function of products. Cranes have further developed new transmission components and simplified the organization. The three-in-one operation organization integrates motors, reducers and brakes. It has the advantages of compact structure, beautiful shape, convenient disassembly and assembly, simple adjustment, stable operation, and large support range.
New products have been widely used. Only by continuous innovation and improving the performance of cranes can it be of great help to the safety and stability of operation. Electric hoists are a special lifting equipment installed on overhead cranes and gantry cranes. Electric hoists have the characteristics of small size, light weight, simple operation, and easy use. They are used in industrial and mining enterprises, warehousing, docks and other places. Now the operation of cranes is relatively simple, and there is no greater risk than before, and safety measures have been increased (referring to solutions to problems).
