JKMD Friction Mining Hoist Winch

High-performance core equipment for large-scale deep-shaft mines. Based on flexible body friction transmission, it achieves collaborative load-bearing through multiple wire ropes, breaking limits of traditional single-rope drum hoists in lifting height and load capacity. Key equipment for mines with annual output exceeding 4 million tons.
Offers two installation configurations:

○Tower-mounted type: compact structure, high stability, suitable for new large-scale mines with limited surface space.

○Floor-mounted type: eliminates need for headframe, short construction period, low cost, easy maintenance, ideal for renovation and expansion projects.

1. The main shaft assembly serves as power execution unit;

2. The drive system offers optional solutions: "variable frequency motor + gear reducer" or the more advanced "low-speed motor direct drive";

3. The braking system uses rear-cylinder disc brakes combined with a constant deceleration hydraulic power station to provide dual safety guarantees;

4. The sheave deflector wheel assembly adopts eccentric design polymer liners to reduce wear;

5. The electrical control system integrates intelligent control functions such as digital speed regulation, PLC control, automatic zero adjustment and online monitoring;

6. Auxiliary devices, rope groove turning device, ensure uniform tension of the steel wire ropes.

The product specifications listed in this table are the preferred specifications.
During selection, if the anti-slip calculation of the system does not meet the requirements, the entire hoisting system may be adjusted. If the requirements are still not met, select the next higher specification.
For large multi-rope friction hoists with high installed power, where single-drive transmission cannot meet operational requirements, TypeⅣ dual-motor drive is preferred.
