High Quality Explosion Proof Electric Hoist
Product attributes
The motor and electrical appliances of explosion proof wire rope electric hoist are explosion proof types. When explosion proof grade is ExdIICT4, travelling mechanism should do spark proof treatment. It can be installed under workshop fixed spending rail to be used individually or to work together with 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 and working environment temperature is -25~40 centigrade degrees.
HB series explosion proof electric hoist adapts to the factory environment where the explosive gas formed by inflammable gas, steam and air, explosion proof grade is less than B grade or C grade and ignition group is more than T4(135 centigrade degrees) group.
The explosion proof electric hoist adapts to 1 area or 2 area, not 0 area.
The explosion-proof characteristic GB3836.2-2000<< Flame-proof "d"- - Electrical Apparatus Used in Explosive Atmosphere Part 2 >> can be made into flame-proof type. This range of motors, whose explosive marking is d I, dIIAT4, dIIBT4 and dIICT4, respectively used in places where there are flammable gas and the mixture of the vapour and air in the coal minging and factory where the protection degree is IIA,IIB or IIC and temperature is T1-T4.
Duty type is M4, whose the basic load continuity is 25% and theequivalent starting times is 120every hour.
Explosion-proof form is "Exd" .
Designed, produced, checked and accepted basing on rule of GB3836-2000
The Exmark are dIIBT4 or dIICT4.
Temperature scale is Class T1-T4 mixture with explosive air (as table one and two).

Application
It can be installed under workshop fixed suspending rail to use individually and can be used together with LXB explosion proof electric suspending single girder crane, and LB explosion proof electric single girder crane and explosion proof electric hoist double girder cranes.
It also can foot mounted in some where to do as winches lifting and transporting heavy materials. It can be used in the place of explosive gas and dust, inflammable and explosive environment. Working temperature: -20-60℃
1 The 220V direct control or other national standard voltage,
2 The single speed of double speed lifting motor,
3 Manual or electric trolley, with I-beam, H-beam, or KBK-lightweight flexible modular crane,
4 The radio telecontrol,
5 Large chain bag(for high lifting height).
Features and advantages
1:Fire stopper: Adjustable mechanical memory structure, high sensitivity
2:Weight limiting stopper: preventing hook clashing the top, sensitive reaction. Safe and durable, easy to install and debug.
3:Overload limiter: Preset related data according working condition, show accurate weight value clearly . Modular, low power design
4:Lifting mechanism configuration has a support brake and a safety brakes, when tapered motor brake failure or intermediate transmission links fails, installed in high speed reducer shaft of the dc electromagnetic brake or installed in the drum brake began to action, ratchet wheel brake, avoid heavy weight to stall dangerous
5:Lifting motor and running the insulation of the motor by H class and grade in lifting motor overheating protection device placed in the windings
Working Conditions
0 areas: Under normal circumstances, the situation that explosive gas mixture appears continuously in a very short time or exists for a long time.
1 area: Under normal circumstances, the situation that explosive gas mixture may appears.
2 areas: Under normal circumstances, explosive gas mixture can not appear. But under abnormal circumstances that equipment is out of order or disoperation takes place, the explosive gas mixture appears occasionally in a short time.
Dangerous gas together with which explosion proof electric hoist can be used is listed as follows. Refer to the appendix of GB3836.1 for other dangerous gas that has not been listed in the following table.
