HB model electric hoist

Description

Motor and electrical appliances of HB explosion proof electric hoist are explosion proof type. *****:0.***2t 2.hoisting height:***0m 3.working system:A5 ***** of working environment:**5°C~*0°C. 5.When explosion proof grade is ExdIICT4, travelling mechanism should do spark proof treatment. ***** whole machine meets standards of JB/T*********1<explosion proof wire rope tric hoist > ***** proof grade: ExdIIBT4 and ExdIICT4. ***** installed under workshop fixed spending rail to use . 9.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. *0.Adapting to the 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(**5°C)group. *1.Adapting to 1 area or 2 area, not 0 area. Notes: 1)0 area: Under normal circumstances, the situation that explosive gas mixture appear continuously in a very short time or exist for a long time. 2)1 area: Under normal circumstances, the situation that explosive gas mixture maybe appear. 3)2 area: Under normal circumstances, explosive gas mixture cannot 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.
