Electric Chain Hoist
Explosion Proof Electric Hoist is a light lifting equipment. Its structure is more reasonable and its assembly is more convenient, and it's propery is more superior. compact structure, light weight, small volume, large lifting capacity, improve labor condition. When workshop filled with explosive mixture, in order to ensure safe premise, explosion-proof electric hoist is necessary.
Lifting height is 6m-18m, and ambient temperature is -25~40°C, and working duty is A3. Its suitable for indoor use; When used in outdoor, need to add protective device. It is applicable in such occasions as easily combustible, explosive, corrosive aid/alkila/plating and mixture gas,it could guarantee secure enough.
If you have any special needs, we can make special design.
