The JZ series sinking winch is mainly used in coal mines, metal mines, and non-metal mines for vertical shaft construction. It is designed for suspending sinking platforms, pumps, ventilation ducts, compressed air pipes, grouting pipes, and other excavation equipment, as well as fortensioning guide ropes. It can also be used for replacing the wire ropes of multi-rope friction hoists, temporary shaft hoisting, and for lifting heavy objects both underground and on the surface. This hoist is intended for short-term duty and is not suitable for continuous heavy-load operation. Carrying personnel is strictly prohibited.
The product is designed and manufactured in accordance with Q/HBWFJZ001 “Shaft Sinking Hoist”, AQ 1031-2007 “Safety Inspection Specifications for Shaft Sinking Hoists Used in Coal Mines”, and GB/T 15112-2007 “Shaft Sinking Hoist”.
Working Principle:When the main motor is started, the motor rotor transmits power through an elastic coupling to the high-speed shaft of the reducer. After speed reduction, the torque is transferred via a crosshead coupling to the main shaft assembly, driving the drum to wind or unwind the wire rope. Byreversing the motor direction, the drum enables periodic reciprocating motion of the load, ensuring continuous torque supply to meet operational requirements.
