Dock cranes are generally used at docks, and are generally open-air operations. They need to withstand wind and rain. In harsh environments, attention should be paid to maintaining dock cranes to reduce equipment losses. Electric hoists are a special type of lifting equipment installed on overhead cranes and gantry cranes. Electric hoists have the characteristics of small size, light weight, simple operation, and convenient use. They are used in industrial and mining enterprises, warehouses, docks and other places. Among many maintenance operations, anti-rust work for dock cranes is essential.
Dock cranes
Where the paint film on the metal structure is damaged, the surface of the component should be cleaned and then coated with anti-rust paint and decorative paint film to reduce the corrosion of the metal in rainy and snowy weather (interpretation: refers to decay, disappearance, corrosion, etc.). 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 scale, large width scale, bulky structure, low mechanical efficiency, and difficult processing. The hydraulic system is controlled by two layers, and the overflow regulating valve and magnetic contact pressure gauge can accurately control the pressure. The electrical control part adopts low voltage control, which increases the safety of the control system. In the moving parts of the crane, such as the connecting pins between the sling and the crane, the guide wheels, the wheels of the trolley, etc., the rust prevention work should be done carefully. First, clean the surface of the parts, and then lubricate these parts with -10 or -20 diesel to make an oil film on the metal surface, and then apply a layer of lubricating oil, but don't apply it too thick.
Port crane
The rust prevention maintenance of the port crane is indispensable. The crane is a frequently used equipment. Safety and reliability are the main things. The good performance of some parts can ensure the reliable operation of the crane. The electric hoist is a special lifting equipment installed on the overhead crane and gantry crane. The electric hoist has the characteristics of small size, light weight, simple operation and convenient use. It is used in industrial and mining enterprises, warehousing, docks and other places.
