Product introduction:
Explosion-proof electric hoist is a light and small lifting equipment, suitable for places with ⅡA, ⅡB, and ⅡC grades, and the temperature group is T1-T4 group of flammable gas or explosive gas mixture composed of steam and air. The working environment temperature is -25℃~40℃, suitable for indoor use; when used outdoors, protective devices are required.
The explosion-proof electric hoist is an explosion-proof hoisting equipment designed and manufactured according to China’s latest explosion-proof standards. Its explosion-proof form is an “explosion-proof” explosion-proof electric hoist. The exposed explosion-proof parts of the hoist are made of special non-sparking materials, and the explosion-proof performance is safe and reliable. The product has passed the explosion-proof performance test of the Jiamusi Branch of the Explosion-proof Electrical Product Quality Supervision and Inspection Center of the Ministry of Machinery Industry, and issued an explosion-proof certificate.

Mechanical Parts:
1, The electrical components of the electric hoist include: lifting and running motors, control boxes, control buttons, stoppers, etc., all use self-contained explosion-proof equipment.
- Use soft cable type power inlet.
- Explosion-proof measures are taken for the mechanical parts, in order to prevent the electric hoist from friction and high temperature sparks generated by impact, the relevant parts are treated.
(1) Inject proper amount of mechanical oil into the lifting and running reducer.
(2) Grease the reel and wire rope.
(3) The left and right stop blocks on the limit rod and the limiter sockets of the limiter are made of bronze or stainless steel.
- The surface temperature of the electric hoist during normal working hours should not exceed 110°C.
Safety System:
- The explosion-proof electric hoist is composed of several parts that can be disassembled separately. It is very convenient to use, maintain and repair, and can shorten the repair cycle.
- The explosion-proof motor and explosion-proof control box are separate explosion-proof structures. The control buttons, limit switches, and explosion-proof lifting weight limiter all meet the corresponding explosion-proof requirements.
- The parts are widely used and interchangeable.
- The reducer adopts standard modular cylindrical gears, which is convenient for maintenance.
