简介 A Brief Introduction
矿用防爆钢丝绳电动葫芦（此种矿用电动葫芦续配备煤安证）根据GB3836.1-2000《爆炸性气体环境用防爆电器设备 第一部分：通用要求》及GB3836.2-2000《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，防爆级别为ExdⅡCT4时，运行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ExdⅡBT4、 ExdⅡCT4.本机可与车间固定悬挂轨道配合单独使用，也可与LXB防爆电机悬挂单梁 、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-25℃~40℃。
According to GB3836.1-2000《explosive gas atmosphere use explosion-proof electric equipment Part1:common requirements》andGB3836.2-2000《explosive gas atmosphere use explosion-Proof electric equipment Part2:flameproof type d》，motor and electrical appliances of explosion proof wire rope electric hoist are explosion proof type. When explosion proof grade is ExdⅡCT4，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 ExdⅡBT4 and ExdⅡCT4 two kinds. It can be installed under workshop fixed suspending rail to use inpidually 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-25℃~40℃。
矿用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(135℃)组的可燃性气体、蒸汽与空气形成的爆炸性气体环境中，所使用的危险区域为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 (135℃) group. And the explosion proof electric hoist adapts to 1 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 maybe 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.
矿用防爆钢丝绳电动葫芦所使用的危险气体举例见下表，未列入表内的其他危险气体见GB3836.1之附录。
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.
