BCD Explosion-proof Electric Hoist

Production Details

Explosion proof electric hoist 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. The main parameters of the hoist is as follow:

Applications of explosion-proof electric hoist

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 of explosion proof electric hoist

Explosion proof electric hoist from DQCRANES 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.

Production Features

Features of explosion proof electric hoist

Explosion proof electric hoist from DQCRANES has the following features:

1. On lifting motor

• Lifting motor used in explosion proof hoist is fully closed tapered rotor asynchronous motor of explosion-proof motor series.
• Max .torque of lifting motor is 2-3 times of full loading, ensuring the safety and reliability of explosion proof hoist.
• The lifting motor has the insulation class of B or F and the protection class is IP44/IP54.

2. Lifting reducer

• Explosion proof hoist adopts standardized modulus of cylindrical gears, installed with antifriction bearing, which is convenient to maintenance.
• High strength gear and gear shaft are made from heat treated alloy steel.
• Lifting reducer shell is made of high quality cast iron which is closely assembled and is dust proof.
• The lifting reducer can work reliably and high efficiency.

3. On hook

• The hook of explosion proof electric hoist is made of high quality carbon steel, supported in the hook beam through a single scroll thrust bearing, free oscillation.
• Hook for 5t and below loads is single slippery wheel whereas hook for 10t or heavier loads is double slide wheel.
• Explosion proof hoist use hooks with card board type structure at hook end.
• When explosion proof hoist is applied to application of explosion –proof dllCT4, the hood head will be made from stainless steel.
• Protection devices are adopted, such as, up and down traveling limiter, overloading limiter, and anti-clashing devices, etc.

4. Operation

Explosion proof electric hoist can be operated through wire rope control and remote control. The explosion proof switches is safe and reliable.
