Provide durable mine safe equipment for you
This crane 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(135DC) group. And the explosion proof electric hoist adapts to 1 area or 2 area, not 0 area.
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 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. QB explosive-proof crane, MZ grab crane and a variety of small- scale mining lifting equipment like electric chain hoist and electric winch are designed especially for mining. The hand operation hoist can be used in special dangerous environment places without electricity.
Automatic control functions make it simple and easy for crane operation. You can move the load to the final destination at any time. The crane includes protection components and operator’s protective device and other safety devices.
