HB Model Explosion Proof Wire Rope Electric hoist

According to GB 3836.1-2000<explosive gas atmosphere use explosion-proof electric equipment Part1:common requirements>and GB3836.2-2000<explosive gas atmosphere use explosion-proof electric equipment Part2:flameproof type d>,motor and electrical appliancesof explosion proof wirerope electric hoist are explosion proof type.When explosion proof grade is Exd 2 CT4,travelling mechanism should do spark proof treatment. The whole machine meets standards of JB/T10222-2001<explosion proof wire rope electric hoist>, explosion proof grade haveExd2 BT4 and Exd2 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 siingle girder crane and explosion proof electric hoist double girder crane.The capacity is 1t 32t,working environment temperature is -25°C 40°C. HB series explosion proof electric hoist adapts to the environment in factory that have explosive gas formde 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(135°C) group.And the explosion proof electric hoist adapts to1 area or 2area,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.
