Product working principle
The JTK and 2JTK mine hoist winches consist of the main shaft assembly, safety brake, depth indicator, reducer, working brake system, gear coupling, electric motor, and electrical control system. These winches are primarily used in coal, metal, and non-metal mines for lifting materials in surface or underground inclined drifts and small vertical shafts.
The JTK / 2JTK series is designed and manufactured in accordance with:
Enterprise Standard Q/HBWF001-2007 – JTK Mine Hoist Winch (HebiWanfeng Mining Machinery Co., Ltd.)
Industry Safety Standard AQ1032-2007 – Safety Inspection Code for JTK Mine Hoist Winch for Coal Mines (PRC)
