- Jun 04, 2018 -

When purchasing explosion-proof gourds, different explosion-proof grade equipment should be selected according to the different types of dust or gas used.Explosion-proof marks for d Ⅱ BT4 and d Ⅱ CT4, apply to A level for the A and B Ⅱ Ⅱ, Ⅱ C level, temperature classes for T1 - T4 group of combustible gas, steam and air 1 zone and 2 zone of the sites with explosive air mixture.The following is the explosion-proof electric hoist rating and the suitable environment range.

The explosion-proof electric hoist can also be installed on the suspended i-beam, the curve track, the guide rail of the swing arm crane and the fixed lifting point.The natural temperature group can be divided into T1, T2, T3 and T4.

Riot grade: DIIAT1 ethane, propane, acetone, styrene, benzene, chlorobenzene, carbon monoxide, ammonia, acetic acid, toluene.DIIAT2 butane, ethanol, propylene, butyl acetate, amyl acetate, cyclopentane, butanol, vinyl chloride.DIIAT3 pentane, heptane, octane, decane.DIIAT4 acetaldehyde.Riot grade DIIBT1 propargyne, acrylonitrile.DIIBT2 epoxy ethane, butadiene, ethylene.DIIBT3 hydrogen sulfide, dimethyl ether.DIIBT4 diethyl ether.DIICT4 hydrogen, water gas.DIICT2 acetylene
