Coal mining Explosion-proof electric hoist

mining electric hoist are specifically designed to meet electrical standards required in hazardous or classified manufacturing and processing areas, it could used underground in coal mining places. professionally used to handle material in coal mine, coal pit, bure, colliery, etc.

Brief introduction:

Since 2008, we achieved the manufacturing license to manufacture coal mine EX electric hoist, coal mine EX chain hoist, coal mine EX single girder overhead crane, double girder overhead crane, and coal mine gantry crane, which are all certified by "MA" certificate. At present, we're the sole manufacturer of "MA" cranes in China.

we are China Only one government permitted company to product "MA" hoists and cranes.

Unique features:

(1) All electrical components are specially design for the coalmine using, which all have "MA" certificate; such as Coalmine EX motors, coalmine Ex electrical box, coalmine Ex limit switches, etc.

(2)Mechanical parts are also of strict Explosion proof measures, adopting explosion-proof or fire proof materials---

a) Hook head has stainless steel packed;

b) Wheel treads adopt stainless steel;

c) The rope mouth of rope guider & hook pulley all adopt copper material;

d) Chain hoist's chain pulleys, clutch disc all adopt stainless steel.

mining electric hoist working Conditions:

The mining electric hoist the explosion-proof class is I class protection.

The explosion-proof characteristic GB3836.2-2008<< 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 "MA" , higher grade than dIIBT4 or dIICT4. mining electric hoist Exmark is heigher than DIICT4.

Temperature scale is Class T1-T4 mixture with explosive air (as table one and two).
