1.No electric sparks, solve the anti-explosion problem absolutely.
2.The working system create the necessary condition for high efficiency continuous working.
3.High operation speed, it is 2-3 times by electric chain block, and change the speed necessarily.
4.Ttolerate PH, dust and steam.
5.Small volume, light, the weight is 1/4 or 1/8 of electric chain block.
6.Could work under the bad condition such as high temperature, high dust and poisonous dangerous air. The product is safe, reliable, has well self-locking performance and the over-load protection device.
