JTPB Explosion Proof Mining Hoist Winch

The JTP and 2JTP mining hoists are primarily used in inclined roadways or small vertical shafts of coal mines,metal mines, and non-metal mines for hoisting materials or personnel.

The JTPB mining hoist is a special explosion-proof device designed for flammable and explosive environments (such   as gas or coal dust mines), incorporating specialized explosion-proof technology in its structure and safety features.

The JTP and 2JTP series products comply with the following standards:
AQ1033-2007 “Safety Inspection Specifications for JTP Type Mining Winches in Coal Mines” 

JB/T7888-2010 “Industry Standard for JTP Type Mining Winches in Coal Mines”
Q/HBWF004-2017 “JTP Type Mining Winches”

2010 “JTP Type Mining Hoist,” Q/HBWF004-2017 “JTP Type Mining Hoist,” “Coal Mine Safety Regulations,”
GB16423-2020 “Safety Regulations for Metal and Non-Metal Mines.”

When the main motor is started, power is transmitted from the motor rotor to the high-speed shaft of the reducer viaan elastic coupling. After transmission and reduction through the reducer, power is then transferred from the reducer's driven shaft to the main shaft assembly via a gear coupling.

By continuously reversing the motor's rotation direction, the drum can either wind or release the steel wire rope, enabling the hoisting container to perform periodic reciprocating vertical movement within the shaft.
