JKMD Multi-Rope Friction Hoist

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.
