According to GB3836.1-2000 [explosive gas atmosphere use explosion-proof electric equipment Part 1: common requirement] and GB3836.2-2000 [explosive gas atmosphere use explosion-proof electric equipment Part 2 flameproof type d], motor and electrical appliances of explosion proof wire rope electric hoist are explosion proof type. When explosion proof grade is Exd II CT4, traveling mechanism  should do spark proof treatment. The whole machine meets standard of JB/T10222-2001 [explosion proof wire rope electric hoist], explosion proof grade have Exd II BT4 and Exd II CT4 two kinds. It can be installed under workshop fixed suspending rail to use individually and can be used together with LXB explosion proof electric suspension single girder crane, LB explosion proof electric single girder crane and explosion proof electric hoist double girder crane. The capacity is 1t-32t, working environment temperature is -25ºC~40ºC.
 HB series explosion proof electric hoist adapts to environment in factory that have explosive gas formed by inflammable gas, steam and air of which explosion proof grade is less than B grade or C grade and ignition group is more than T4(135ºC) group. And the explosion proof electric hoist adapts to 1 area or 2 area, not 0 area.
Notes: 0 area: Under normal circumstances, the situation that explosive gas mixture appear continuously in a very short time or exist for a long time.
   1 area: Under normal circumstances, the situation that explosive gas mixture maybe appear.
   2 area: Under normal circumstances, explosive gas mixture can not appear, but under abnormal circumstances that equipment is out of order or misoperation takes place, the explosive gas mixture appears occasionally in a short time.
Â
Dangerous gas that explosion proof electric hoist can be used in is listed as follows. Refer to the appendix of GB3836.1 for other dangerous gas that has not been listed into the follow table.
