Friction Winch 1500kg VFD Speed Control Dual Drum Groove | KLD

A friction winch for reciprocating haulage applications, fitted with a VFD motor and an electromagnetic brake for precise travel and accurate positioning. Variable-speed control delivers smooth start and stop, while the dual-drum rope groove design and mechanical limit switch support reliable friction-type running with adjustable stopping positions.

Quick Specs

Wire rope dia.: Ø12 mm       |  Drum speed: 9 rpm
Average rope speed: 4.58 m/min |  Speed control: VFD, 0–5 m/min range
Brake: electromagnetic       |  Limit: mechanical limit switch
Dimensions (L×W×H): 551 × 523 × 380 mm

Application Scenarios and Applicable Boundaries

- Reciprocating haulage — traction duties requiring repeated forward and reverse travel.
- Positioned stopping — mechanical limit switch sets the stop position per site requirements to help avoid over-travel and collision.
- Variable-speed processes — VFD control adjusts rope speed to suit each stage of the operation.
- Rail or trolley travel — suitable for guided transfer and trolley haulage layouts.

Boundary: Rated pull, duty and rope specification must be confirmed against the actual application and the case drawing. Standard configurations are not intended for personnel lifting.

Features Benefits

Smooth travel — VFD speed control provides smooth running with soft start and soft stop.
Designed for friction duty — the dual-drum rope groove design provides ample drive for friction-type running and helps prevent rope slipping.
Better accuracy — multiple rope grooves improve accuracy and precision and help reduce rope wear.
Adjustable stopping — the mechanical limit switch sets the stop position according to site requirements to help avoid over-travel and collision, improving safety and efficiency.

Standards Testing and Quality

The company operates an ISO 9001 quality management system. CE conformity documents (LVD, EMC) are available for applicable configurations on request.

Factory testing follows the approved technical specification for each configured unit and may include: no-load run, rated-load operation, brake function, independent-motor control verification, limit and encoder function checks. Available documentation may include dimensional drawings, electrical diagrams, inspection records and functional test results, depending on project scope.
