HYBDB series explosion-proof chain electric hoist hereinafter referred to as explosion-proof hoist, according to provisions GB3836.1-2010《General Requirements for Equipment in Explosive Atmospheres Part 1》, GB3836.2-2010 《Explosive Atmospheres Part 2, Equipment protected by an outer layer “d”》、JB/T 1022-2011《Explosion-proof electric hoist》, JB/T 5317-2007《Electric chain hoist》and Q/LA0003-2014 《explosion-proof electric chain hoists》. The flameproof explosion-proof “EX d IIC T4 Gb”, which is suitable for the protection of workplaces with the danger of explosive gas and explosive mixture formed by vapor and air in factories. All electrical product accessories of this product must have the same explosion-proof certificate as the explosion-proof hoist. It is strictly forbidden to use the explosion-proof hoist to lift and transport personnel.
Example of model marking:
In an explosive gas environment, the explosion-proof mark is EX d IIC T4 Gb . The rated lifting capacity is G=10 tons. Standard building height lifting height H=9 meters, explosion-proof chain with the working level of M3, electric hoist model marked as HYBDB10-9 M3 EX d IIC T4 Gb Q/LA0003-2014.
1. HYBDB series explosion-proof chain electric hoist products can be installed on the I-beam track, and the electric running trolley is used as the running mechanism. It can reciprocate along the track in a straight line and a curve. It can also be fixed to a certain position to lift heavy objects to ensure sufficient safety.
2. This series of explosion-proof chain electric hoists products are compact in structure, light in weight and volume, and large in lifting capacity. On the premise of ensuring safety, it is a powerful supply to improve labor conditions and increase productivity, so it has become a necessary mechanical equipment in a reasonable process.
3. Use environment
①Below 1 kilometer above sea level.
②The ambient air temperature should not be higher than 40 degrees and not lower than minus 20.
③The grid fluctuates within plus or minus 10%.
④Where the relative humidity does not exceed 95% to prevent dripping.
⑤Zones 1 and 2 of the explosive atmosphere of the II C, class T4 temperature group in the factory.
4. This series of products can be used with explosion-proof single-girder cranes according to different requirements.
