Explosion Proof Electric Hoist Specifications 3 Ton, 5 Ton,10 Ton
Safe Electric Hoist for Hazardous Application

Explosion proof electric hoists are specially designed material handling equipment with explosion proof features. Explosion proof electric hoists are designed and manufactured in accordance with GB3836-2000 provisions and international regulations, with the explosion proof mark of D II BT4, and D II CT4, and can be supplied to applications with the level of II A, II B, II C grade, 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 an explosion proof electric hoist ranges from 0.5 to 16 tons, and its working class is M3.

Main features of explosion proof electric hoist

Compact structure, light, safe, and dependable;
Compact structure, light, safe, and dependable;
Explosion-proof hoist exposed parts are all made of non-sparking materials for dependable explosion-proof performance.
Exd II BT4 or Exd II CT4 is the explosion-proof mark, and the temperature class is an explosive gas mixture of the T1-T4 group (see table 1 and 2)
GB3836-2000 planning and design, manufacture, and acceptance
Main application of explosion proof hoist
Hanging from an Ibeam and moving in a straight or curved line
The explosion-proof hoist can be installed in a fixed support and used with an explosion-proof single or double beam crane to lift heavy materials.
Class B and C of type I and type II, places explosive danger with the temperature group of T1-T4.

Appendix:

Grade "explosive-proof"
There are two types of electrical equipment that, when used under certain conditions, will not result in an explosive burning environment:
Type I: underground coal mine electric equipment
Except for underground coal mines, all other explosive environments using electric equipment are classified as Type II..

Type II can be divided into IIA/ IIB/ IIC.

Main structure and characters of explosion proof electric hoist

Classification and product specifications

Explosion-proof single speed type and explosion-proof double speed type.

Note: single speed explosion-proof traveling electric hoist, with the capacity 5t and lifting height 9m, can be signed as BCD 5t-9m.

Structure Layout

Stationary type and operation type both included.

As shown on the right: A1、A2、A3、A4 separately fixed on the up, down, left and right side. A2 always used on the trolley of double beam crane with hoist. It is usually operation type without special explanation, traveling along with beams.

Lifting motor

Adopt professional manufactured fully enclosed tapered rotor asynchronous explosion-proof series motor
Max torque is 2 or 3 times more than full-load torque, safe and reliable when using
Grade B or F insulation, motor protection degree IP44/IP54

Speed reducer

Adopt standard module cylindrical gear, easy for maintenance, all installed anti-friction bearing
2.The gears and gear shaft are made of high strength heat-treated alloy steel.
3.High quality cast iron shell, machined to shape, assembly rigor, dust proof.
4.The reducer is a separate part that is easy to assemble and disassemble.
5.Reliable and efficient driving.

Hook

1.The hook end is made of cardboard.
2.Stainless steel hook head when the explosion-proof degree is DIIT4.

Traveling mechanism

Traveling motor

1. Flameproof BZDY series conical rotor three-phase asynchronous motor, flat brake, small braking torque, slow braking process to avoid parking hanging heavy objects shaking.
2. S4 motor working duty, 25% benchmark load sustained rate, 120 times equivalent starting per hour

Electric equipment

Explosion-proof type electric control box, explosion-proof type control board, and explosion-proof limiting stopper are included.
With dedicated explosion-proof up and down traveling protection of fire stopper limit device.
With an overload limit of the explosion-proof type.

Explosion proof electric wire rope hoist

Other features are the same as with a standard electric hoist.

Note:mechanical components take explosion-proof measures. In order to prevent electric hoist crash and impact cause high temperature spark when traveling, we should deal with some relevant parts.

(1)The correct amount of machine oil should be injected into the lifting and running reducer.
(2)Reel of grease-coated wire rope.
(3)Stop block in the limited rod and limit apply joint made of bronze or stainless steel
