HB型防爆钢丝绳电动葫芦

爆钢丝绳电动葫芦根据GB3836．1－2000《爆炸性气体环境用防爆电气设备第一部分：通用
要求》及GB3836．2－20000《爆炸性气体环境用防爆电气设备第二部分：隔爆型“d”》的规定，电
机、电器为隔爆型，防爆爆级别为 Exd I CT4B时，运行机机构进行防火花处理。整机符合．JB／T10222
2001《防爆钢丝绳电动葫芦》的规定，防爆等级分别为 Exd BT4、 Exd CT4。本机可与车间固定
悬挂轨道配合单独使用，也可与LXB防防爆电动悬挂单梁、LB防爆电动单梁、防爆葫芦双梁配套使
用。其起重量为1t－32t。工作环境温度为－25C－40C。

   According to GB 3836 1-2000(explosive gas atmosphere use explosion-proof electric
equipment Part 1: common requirements)and GB38362-2000(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 I[ 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
have Exd I 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 1 t-32t, working environment temperature is-25 c-40c

HB型防爆钢丝绳电动葫芦适用于工厂内具有防爆级别不高于B级或C级，引燃温度组别不低于
T4（135C）组的可燃性气体、蒸蒸汽与空气形成的爆炸性气体环境中，所适用的危险区域为1区或
2区，不适用于0区。

HB series explosion proof electric hoist adapts 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 (135C) group And the explosion proof electric hoist
adapts to l area or 2 area, not 0 area.

注：0区：在正常情况下，爆炸性气体混合物连续地、短时间频繁地出现或长时间存在的场
所

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区：在正常情况下，爆炸性气体混合物有可能出现的场所。

1 area: Under normal circumstances, the situation that explosive gas mixture may be appear.

2区：在正常情况下，爆炸性气体混合物不能出现，仅在不正常情况下既有可能发生设备故
障或误操作情况下，偶尔短时间出现的场所。

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.
