Description

Mining 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.
 
 
Since ***8, 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, were the sole manufacturer of MA cranes in China.
 
MA hoists and cranes.
 
(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.
Mechanical parts are also of strict Explosion proof measures, adopting explosion-proof or fire proof materials**-
 b)      Wheel treads adopt stainless steel;
 d)     Chain hoists 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 GB***6.*****8<< 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 T*-T4.
Duty type is M4, whose the basic load continuity is *5% and theequivalent starting times is **0every hour. 

Explosion-proof form is "Exd" .
Designed, produced, checked and accepted basing on rule of  GB********0
The Exmark are  · 1.Compact structure, light weight, safe and reliable
· 3.High lifting capacity, easy maintenance
