Explosion Proof Overhead Crane
.........................................
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 Part2: flameproof typed>,motor and electrical appliances of this crane are explosion proof type. When explosion proof grade is ExdII CT4, travelling mechanism should do spark proof treatment. The whole machine meets standards of JB/T0219<Specification for explosion-proof cranes with electric wire rope hoist>, explosion proof grade have ExdII BT4 and ExdII CT4 two kinds. It has  characteristic of rational construction, perfect appearance and strong Ex technical performance. It can be used together with HB,BCD type explsion proof electric hoist. Its max lifting capacity is 63t and has three types: 1.LXB explosion proof electric single girder suspension crane. 2.LB explosion proof electric single girder crane.3.LHB type explosion proof electric hoist double girder crane. The working class is A3-A4, working environment temperature is -25DC to 40 DC.

This crane adpts 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(135DC) 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 continously in a very short time or exist for a long time.

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.

Dangerous gas that this crane can be used in is listed as follows. Refer to the appendix of GB3836.1 for other dangerous gas that has not been listed in to follow table.
