Explosion-proof electric wire rope hoists are based on ordinary wire rope electric hoists, motors, electrical appliances, and some parts to take explosion-proof measures, according to the different environments, divided into gas explosion-proof and dust explosion-proof.
All kinds of explosion-proof electric wire rope hoists produced by our company are designed, manufactured, and accepted in strict accordance with the following national standards:
- GB/T 3811-2008 《Design rules for cranes》
- GB/T 6067-2010 《Safety rules for lifting appliances》
- GB/T 3836.1-2021 《Explosive atmospheres-Part 1: Equipment-General requirements》；
- GB/T 3836.2-2021 《Explosive atmospheres-Part 2: Equipment protection by flameproof enclosures “d”》；
- JB/T 10222-2011 《Explosion-proof hoist》
The National Center for Supervision and Inspection of Explosion-Proof Electrical Product Quality examines and tests various types of explosion-proof electric wire rope hoists, and after the final test, explosion-proof cranes are issued certificates of conformity.
Types of explosion-proof electric wire rope hoists
HB Explosion-proof electric wire rope hoists
The explosion-proof electric wire rope hoist is based on an ordinary wire rope electric hoist from the motor, electrical design, and manufacture of explosion-proof performance of explosion-proof motor and explosion-proof electrical appliances, and the corresponding mechanical explosion-proof measures assist it. It has the characteristics of lightweight, small volume, compact structure, smooth operation, high safety, and reliability, which can be used in explosion-proof electric iodine excess cranes, explosion-proof electric single girder suspension cranes, explosion-proof electric hoist bridge cranes, can also be used in the I-beam made of fixed rail.
Explosion-proof electric wire rope hoists features:
- In order to ensure the mechanical explosion-proof requirements, the working line speed of all its mechanisms is controlled within 25m/min.
- Use of the environment, temperature -20 ℃ ~ +40 ℃, altitude below 1000m, relative humidity 85% (20 ℃ ± 5 ℃)
- Rated lifting capacity 0.5t~50t.
- The working speed of each organization: the running mechanism is single-speed, the lifting mechanism can be single-speed or double-speed, and each organization can also be non-standard design for frequency conversion and speed regulation.
- The operation form is wired operation on the ground, and can also be designed for remote control operation on the ground.
- Applications: military, nuclear industry, aviation, aerospace, machinery manufacturing, petroleum, chemical and other industries.
