Explosion-Proof Electric Hoist

Explosion Proof Electric Hoist

Explosion Proof Electric Hoist Description
Explosion proof electric hoists are applied in working places which have explosive gas mixture, which is formed by air and II A, II B, II C-class ,T1-T4 temperature group combustible gas or steam. The working environment temperature is-25°C~40°C, suitable for indoor use. If in outdoor use, it's need to add protective devices, can be mounted on single beam bridge crane, gantry crane and jib crane. With slight modification, it can also be used as a winch. It is widely used in steel factories essential in raising working efficiency and improving working conditions.

Introduction
Explosion proof electric hoist is a specially designed material handling equipment with the features of explosion proof. Explosion proof electric hoist is designed and manufactured according to gb3836-2000 provisions and international regulations, with the explosion proof mark of d ii bt4, and d ii ct4, which can be supplied to applications that has the level of ii a, ii b, ii c grade, the temperature sub-groups t1-t4 group of combustible gas, steam and air from the explosion gas mixtures in a zone, zone 2 areas. The lifting capacity of explosion proof electric hoist is 0.5 to 16 tons and working class of explosion proof hoist is m3.
Applications:
Explosion proof electric hoist can be used on the main i-beam track to run in straight or curve line to handle materials or installed on a fixed bracket as a lifting solution for heavy loads. Explosion- proof electric hoist also can be fixed to different applications, working with explosion proof single girder overhead travelling crane or with the explosion proof dual beam bridge crane, etc.
Environmental conditions of explosion proof electric hoist
Explosion proof electric hoist is applied to the environment with the elevation below 1000m, with relative humility, with the class i, class iib and iic.
The temperature scale of explosion proof hoist is class t1-t4 (explosion hazardous area).
Explosion proof electric hoist can be hanged on i beam rail, explosion proof single girder or double girder, or other fixed support for material handling, etc.
Advantages:
Explosion proof electric hoist from dongfengcranes has the following advantages:
1.Compact structure, small size, light weight, large capacity.
2.High safety and reliability.
3.All the spare parts are generalized and changeable, which make hoist maintenance easy and simple.
4.No spark materials are used to the outside parts enhancing anti-explosion ability of electric hoist.
5.Explosion proof electric hoist is designed and manufactured according to gb3836-2000.

5T Explosion Proof Battery Electric Locomotive has followed advantages
1.Energy Saving
This explosion proof battery locomotive adopts internationally advanced direct toque control technology to achieve closed-loop speed control. The energy generated by the motor can be converted to the battery when twitching.
2.Stability
This battery locomotive has a smooth start and zero starting impact
3.Complete Protection
This locomotive has protection of short circuit, under-voltage, over-temperature and lack of phase.

Electric hoist(CD Model)
CD model wire-rope electric hoist is a kind of light-small lifting equipment with advantages of tight structure, light weight, small volume, wide common use and convenient operation etc.If reducers with hard gear surface are applied, it will have long life and high mechanical efficiency. Conic rotor brake motors are equipped which has safety limiter in both up and down directions.
CD model wire-rope electric hoists can be widely used to hoist heavy objects, or installed on the straight or curve I-steel beam of Single-girder Cranes. They can also be used together with Electric Hoist Double-beam, gantry crane and slewing cranes. All the above has made the electric hoists common in industrial and ore enterprises, railway, wharfs and warehouses.
