Shaft Emergency Auxiliary Hoisting System

The vertical shaft emergency auxiliary hoisting system is a dedicated safety rescue device used to emergently lift the cage and trapped personnel in the shaft when the main mine hoist fails (e.g., due to a mine-wide power outage or motor damage).

The main hoist is paralyzed due to power outage, mechanical or electrical failure, trapping personnel in the cage inside the shaft.

In emergency situations, underground operators need to be quickly evacuated to the ground.

Applicable to various mines with vertical shaft hoisting systems, serving as an important safety backup facility.

IPP

Personnel trapped after main hoist system failure with no rescue measures → Provides fully independent power (diesel engine) and control system, independent of the power grid, enabling rapid establishment of emergency hoisting capacity after main system failure to rescue trapped personnel.

Communication interruption and unclear situation in emergency state → Integrates wireless audio and video transmission device, realizing real-time video call between the surface dispatching room and personnel inside the faulty cage, facilitating command and comfort.

Slow startup and complex operation of emergency equipment → The system adopts an integrated design, enabling rapid deployment and startup with multiple operation modes (remote control, local control, upper computer) to adapt to emergency situations.

Independent power, rapid response: Powered by a diesel engine, independent of the external power grid, ensuring rapid rescue deployment under any power outage scenario.

Bi-directional Hoisting, Safe and Reliable: Equipped with bi-directional hoisting capability, lifting force exceeds 300kN. Adopts a semi-open double-spiral linear clamping mechanism for rope holding, featuring high friction coefficient and stable hoisting.

Integrated Design, Easy Operation: The electro-hydraulic control station is highly integrated, providing multiple operation interfaces such as remote and local control, facilitating use in emergency environments.

Audio & Video Connectivity, Smooth Command: Equipped with built-in cage monitoring and surveillance devices, enabling wireless video calls between the surface command center and trapped personnel inside the cage, improving rescue efficiency and safety.
