An explosion proof electric hoist is a type of compact and light material lifting equipment. The explosion proof hoist is lightweight, compact, and has a high lifting capacity. When the workshop is filled with explosive air , substances or combination, it is a useful hoisting equipment for improving working conditions and labor productivity while assuring safety.
The "flameproof" is the explosion proof type of electric wire rope hoist equipment designed and built in accordance with the explosion proof standard. The exposed explosion proof constructions and parts and components of the electric hoist are built of unique non-sparking materials, ensuring safe and reliable explosion proof performance.
Advantages of explosion proof hoist
Yuantai Crane' explosion-proof electric hoist has the following benefits:
- 1.Compact design, compact size, light weight, and great capacity.
- 2. High reliability and safety.
- 3.All spare parts are standardized and interchangeable, making the electric hoist maintenance simple and easy.
- 4.No spark materials are utilized on the external sections, strengthening the electric hoist's anti-explosion capability.
- 5.The electric hoist is designed and manufactured in accordance with GB3836-2000.
Main parameters of explosion proof wire rope hoists
Explosion proof electric hoists can be equipped with electric travelling trolley on i-beam tracks for linear or curve operation, based on the application conditions and lifting requirements, equipped on explosive proof single girder suspension cranes or explosion proof single, double girder bridge cranes or other types of overhead crane It can also be used for just for vertical hoisting which are mounted on the bracket or supporting structure.
- Lifting capacity :0.5t 63 ton, lifting height: 6m 100m, voltage: 220v-660v, three-phase.
- Electric hoist control mode: pendent control or remote control. Wireless remote control is optional;
- Any color can be customized or delivered at random.
The explosion proof hoists passed the explosion proof performance test of the Ministry of Mechanical Industry's explosion proof electrical product quality supervision and inspection center, and the explosion proof certificate are provided.
Main parts of explosion proof wire rope hoists
The explosion proof grade of explosion proof electric hoist is DIIBT4 and DIICT4, the exposed explosion proof parts and components of the wire rope hoist are made of special sparkless materials to ensure safety. The electric hoist are mainly consisted of the motor, electrical appliances, electric travelling wheels or not included in stationary design, rope guide, hook, operation handle, etc. All of the electric hoists and components used are for the hazardous application with explosion proof features to ensure safe and reliable performance.
- MOTOR - Explosion proof electric hoist hoist motor and operation are explosion proof, slightly longer than conventional motor, level for Ecd IICT4.
- LOWER HOOK - The lower hook of electric wire rope hoist is explosion proof.Not only the hook pulley is made of copper, but also the hook head is made of stainless steel.
- HANDLE AND ELECTRICAL BOX - The electric box and handle of the explosion proof electric hoist are both explosion resistant. When compared to a standard electric hoist, the electric box of the explosive proof electric hoist has a larger capacity, heavier weight, a stronger handle, and superior water resistance.
- LIMITER FOR FLAMEOUTS - Explosion proof electric hoist fire limit device is explosion proof, unlike the ordinary large volume, weight, and surface has EX explosion proof mark.
- ROPE GUIDE -Explosion proof wire rope electric hoist rope guide is explosion proof, containing copper.
- TRAVELLING TROLLEY - Explosion proof wire rope electric hoist running wheel, that is, in the conventional manual stainless steel welding Rod running wheel.

Industrial sectors requires for explosion proof hoists
Explosion proof wire rope electric hoist is on the basis of ordinary wire rope electric hoist, motor, electrical appliances and some parts to take explosion proof measures, suitable for containing combustible gas, steam and air combined to form a spark easily flammable and explosive work place (such as coal mine, pharmaceutical factory, chemical plant, etc.).
Explosion proof wire rope electric hoist is developed on the basis of a standard cd/md wire rope electric hoist. The main parts of the explosion proof electric hoist such as motor, electrical appliances, and other parts are designed with explosion proof features, making it suitable for applications with combustible gas, steam, and air combined to form a spark easily flammable and explosive work environment. They are widely used in applications such as such as coal mine, pharmaceutical factory, chemical plant, etc.
Environmental conditions of explosion proof hoist
BCD explosion proof electric wire rope hoist adapts to the environment in factory that has explosive gas formed by inflammable gas, steam, and air of which explosion proof grade is less than B grade or C grade and ignition group is more than T4(135°C)group. and the explosion proof hoist are applicable to 1 area or 2 area.
- Area 0: Normally, an explosive gas mixture condition would appear continually in a short amount of time or last for a considerable amount of time.
- Area 1 : Under normal circumstances, an explosive gas combination maybe appear
- Area 2: Under normal conditions, the explosive gas combination cannot arise; nevertheless, when the equipment is out of order or misoperation occurs, the explosive gas mixture appears on occasion in a short period of time.
The working temperature range is - 25 °C to 40 °C, making it ideal for indoor application; when used outdoors, protection measures should be provided.
