Product IntroductionThe JK/2JK series single-rope winding mine hoist is suitable for the continuous and efficient transportation of materials, equipment, and personnel weighing 6 to 17 tons. It is widely used in metal and non-metal mines such as gold mines, copper mines, and iron mines. The hoist can be deployed in various scenarios, including surface industrial yards, underground inclined roadways, and medium to large vertical shafts, enabling efficient, reliable, and continuous lifting and lowering of ores, equipment, and personnel.
Structural Features and Working Principle
The hoist adopts a modular design, integrating a main shaft assembly, reducer, YVF variable-frequency motor, and an intelligent electrical control system. During operation, the variable-frequency motor drives the reducer through an elastic coupling. The speed is reduced via a two-stage helical gear transmission, and the rotation is then transmitted to the drum via a drum gear coupling. The brake control system precisely regulates the motor's forward and reverse rotation as well as speed adjustment, enabling intelligent winding and unwinding of the wire rope to accomplish lifting tasks. The system features closed-loop speed control, travel detection, and a control system that enables full-process monitoring and multiple protections, ensuring smooth wire rope handling and an efficient, stable, and reliable lifting process.
Main Hoisting Operations: ◎Hoisting Ore/Waste Rock: Lifting mined ore or waste rock generated from tunneling operations from underground to the surface. ◎Lowering Materials and Equipment: Transporting hanging platforms, support materials, equipment components, and other supplies from the surface to various levels underground. |
Auxiliary Hoisting Operations: ◎Personnel Transportation: Operating with a cage to transport miners to and from the mine. ◎Completing Specific Processes: During shaft sinking, used for hoisting buckets and suspending sinking equipment (such as hanging platforms, safety ladders), etc. |

ApplicationMain AdvantagesCompared to single-drum hoists, the 2JK double-drum hoist offers the following outstanding advantages:
High Hoisting Capacity, Suitable for Deep Shafts: The double-drum structure provides a larger rope capacity, making it suitable for medium-depth and deep shaft mining. It meets the demands for large hoisting volumes and high hoisting speeds |
Flexible Operation, Adaptable to Complex Conditions: It is particularly well-suited for mines with multi-level operations, capable of flexibly adapting to hoisting demands at varying depths. It performs effectively during both the shaft sinking and mine production phases, demonstrating strong versatility |
Safe and Reliable: Equipped with comprehensive electrical control systems (such as variable frequency speed regulation and PLC control) and mechanical safety devices (disc brakes, overwind protection, etc.), ensuring smooth operation, precise control, and a high degree of safety redundancy. |
