JKZ/2JKZ Mine Shaft Sinking Hoist

Les JKZ/2JKZ series represents large-scale specialized hoisting equipment designed for vertical shaft excavation in coal, metal, and non-metallic mines. These winches serve critical roles during mine construction, enabling safe and efficient lifting of personnel, waste rock, concrete, and heavy equipment. The series includes single-cylinder (JKZ) and double-drum (2JKZ) configurations. As temporary equipment, they are optimized for mobility and reinstallation at new shaft sites post-excavation.

Core Applications: Specifically designed for the safe and efficient vertical transportation of personnel, waste rock, concrete, construction equipment, and materials during shaft excavation.

Key Operations: Capable of undertaking core specialized tasks in shaft drilling projects, such as hoisting umbrella drills for drilling operations, lowering integral metal formwork for shaft wall pouring, and stabilizing multi-layered suspended platforms as work platforms.

Applications : Widely applicable to new or expanded vertical shaft projects in various mine types, including coal mines, metal mines, and non-metal mines.

Selection Principles: Equipment selection is not a standard application but requires strict and specific calculations based on safety regulations, such as the “Coal Mine Safety Regulations,” considering key parameters such as shaft depth, bucket volume, and rock grabber productivity for each project. This ensures that the hoist capacity (wire rope safety factor, motor power, reducer torque, etc.) precisely matches the peak construction capacity.
