At present, most of the building electric hoists on the market are climbing frames, also known as climbing frame electric hoists, synchronous electric hoists, cranes and other names. The advantage of the climbing frame electric hoist is its compact structure. The electric hoist with the motor axis perpendicular to the drum axis adopts a worm gear transmission device. However, there are also disadvantages such as: large length dimension, large width dimension, bulky structure, low mechanical efficiency, and difficult processing. The hydraulic system of the climbing frame electric hoist is dual-controlled, and the pressure can be accurately controlled by the overflow regulating valve and the magnetic contact pressure gauge. Climbing frame electric hoist is a kind of special lifting equipment, most of which are installed on cranes and gantry cranes. Common electric hoists have the characteristics of small size, light weight, simple operation and convenient use. They are used in industrial and mining enterprises, storage, Wharf and other places. The lifting capacity is mostly 0.3 to 80 tons, and the lifting height is 3 to 30 meters. Among them, the electric chain hoist is divided into two types: imported and domestic; the specifications of the wire rope electric hoist are divided into single-speed hoisting and double-speed hoisting; miniature electric hoist, hoist, and multi-function hoist are various specifications. Climbing frame electric hoist use: mostly used in processing workshops, warehouses, docks, various modern production lines, assembly lines. In the workplace, it has its advantages in small footprint, flexible, fast, safe, and convenient use. It can also be applied to the climbing frame, climbing form lifting, group crane, etc. of large oil tanks in the field of construction engineering. The price of climbing frame electric hoist is similar to that of ordinary chain electric hoist.
