HB, HBS. BHC. BCD explosion proof electric hoist is a series of products

The explosion proof motors, explosion proof electrical appliances, etc. used in this product, whether designed and manufactured by our own factory or produced by supporting factories, are all in accordance with the national standard GB3836.1-2000 “Electrical Equipment for Explosive Gas Environments: General Requirements” , GB3836.2-2000 “Electrical Equipment for Explosive Gas Environments: Flameproof D” and other relevant regulations designed, manufactured and accepted, and reviewed by the state-designated inspection unit, Nanyang Branch of China Explosion-Proof Electrical Products Testing Center , Test well test for qualified factory explosion proof lifting equipment.

This product must be used in strict compliance with the conditions specified in the “Instruction Manual”.

1. Scope of application

1. The explosion-proof electric hoist is a series product, which is designed and manufactured according to GB3836.1-2000 “Electrical Equipment for Explosion proof Gas Environment: General Requirements”.

2. This series of three-level explosion-proof electric hoist is suitable for when there is an explosive mixture of flammable gas, steam and air specified in Table 1 in the workshop; this series of four-level electric hoist is suitable for when there is a flammable mixture in the workshop. When the explosive mixture is formed by gas, steam and air; it is installed on the I-shaped steel rail to lift heavy objects, and can reciprocate linearly and curvedly along the rail to ensure sufficient safety.

3. This series of products have compact structure, light weight, small volume lifting capacity, when the plant is full of explosive mixtures, under the premise of ensuring safety, is a favorable tool to improve labor conditions and labor productivity, thus becoming a reasonable process must be mechanical equipment.

4. Use environment: temperature -20C-+40℃, altitude below 1000M, relative humidity 85% (20 soil 5℃)

5. The series of products can be used with LXB explosion-proof single-girder suspension crane or LB, LHB explosion-proof single and double-girder bridge cranes according to different use requirements.。
