With the increasing number of commercial performances and various performances, the use of climbing frame hoists has also increased dramatically. In recent years, by continuously improving the level of scientific research, the performance of the equipment has been effectively adjusted, and great improvements have been made in quality. In the future, the value of climbing frame electric hoist will definitely increase greatly. The electric hoist of climbing frame is a kind of special lifting equipment, usually installed on overhead crane and gantry crane. The climbing frame electric hoist has the characteristics of small size, light weight, simple operation, etc. It is widely used in industrial and mining enterprises, storage docks and other places. The electric hoist of climbing frame is mainly classified into electric chain hoist, electric hoist with wire rope (explosion-proof hoist), double hoist electric hoist and other product series. The electric wire rope hoist is characterized by a small length and an electric hoist whose motor is installed inside the drum. The electric hoist has a compact structure, and the electric hoist with the motor axis perpendicular to the reel axis adopts a worm gear transmission device. But its shortcomings are large size in product length and width, bulky structure, low mechanical efficiency and so on. The hydraulic pressure is dual control, and the pressure can be controlled by the overflow regulating valve and the magnetic contact pressure gauge. The electrical control department is controlled by the low voltage, but there are no manufacturers in the market to produce this type of structure.
So what are the characteristics of climbing frame electric hoist? The lifting weight of climbing frame electric hoist is usually 0.180 tons, and the lifting height is about 330 meters. It is composed of motor drive organization and drum or sprocket. The product is also divided into two different types: wire rope electric hoist and ring chain electric hoist Products. The ring chain electric hoist is divided into imported and domestic ones; the wire rope electric hoist is divided into CD1 type and MD1 type; micro electric hoist, winch and other products.
Specification for use of climbing frame electric hoist
1. Equipment operation should be monitored, ground power switch and warning sign
2. Operators should wear protective labor protection products
3. The installation or disassembly of the tower crane shall be carried out in accordance with the prescribed procedures
4. During the operation of the truck crane, the distance between the equipment and the lifting items and the electric wires in the operation cannot be guaranteed.
