The new group of electric hoist crane

　　Hoisting electric hoist is a kind of low-speed electric hoist, a kind of light small lifting machinery, it retains the characteristics of chainhoists convenience, but also improved the manual chain hoists, lifting speed is slow, it sets the electric hoist and chain hoist with the advantages of a body, with lifting speed slow, light weight, high mechanical hardness, low wear characteristics. Because the utility model has the advantages of flexible and quick use in a small space, the utility model is also suitable for the construction of the climbing frame in the field of construction engineering, the lifting of the climbing formwork, and the hanging of the large oil tank.

　　The new type of electric hoist, which is produced by Yu Di, greatly improves the safety performance of electric hoist.

　　1, Yu carved a new group of hanging electric hoist using three point positioning, that is, the cover of the three bearings, the extension of the long axis of the five teeth, with the bearing transmission, lower noise, more stable performance.

　　2, the impact of the external impact of the gear box and the outer cover, the use of thick plate processing of the gear box cover, the external impact is not easy to damage.

　　The chain plate 3 and a new, convenient chain disassembly, maintenance more convenient.

　　4, the planetary gear structure, all transmission gears, gear ring are made of alloy structure steel after heat treatment Seiko production, low noise, smooth operation, longer life.

　　The new type of electric hoist has been applied for patent, and the quality is guaranteed.
