Explosion Proof Friction Winch 2000kg CT4 VFD Motor Conveyor Hub | KLD

An electric friction winch with CT4 explosion protection, built with low power consumption and high power output for quiet operation and reduced maintenance. It combines an explosion-proof VFD geared motor with an electromagnetic brake and integrated program control. Typical duty: hauling cars at mine conveyor hubs on 45° inclined transfer points, with automatic lifting or lowering.

Quick Specs

Rated pull: 2000 kg          |  Motor: 4 kW (explosion-proof VFD)
Rope dia.: Ø12 mm            |  Rope speed: 5 m/min
Duty class: M4               |  Protection class: CT4
Brake: electromagnetic       |  Control: integrated program control
Dimensions (L×W×H): 992 × 726 × 410 mm

Application Scenarios and Applicable Boundaries

- Mine conveyor hubs — hauling cars on transfer points, including 45° inclined sections with automatic lifting or lowering.
- Hazardous environments — CT4 protection class configuration for areas requiring explosion-proof equipment.
- Automatic duty cycles — integrated program control supports automated operation to improve efficiency and accuracy.
- Quiet, low-maintenance sites — low-noise running and a reduced-maintenance design lower running costs.

Boundary: Only the case configuration carries the stated CT4 protection class; protection class, motor type and control must be confirmed against the actual hazardous-area classification (gas/dust zone) before ordering. Standard configurations are not intended for personnel lifting.

Features Benefits

Hazardous-area ready — CT4 protection class supports safe operation in explosive-risk environments, helping reduce explosion risk.
Efficient drive — low power consumption design with high power output improves working efficiency and reduces energy consumption.
Quieter workplace — quiet running reduces noise and improves the working environment.
