Heavy Duty Traction Winch 8000kg 500m SEW Motor | KLD

Engineered for lifting and pulling heavy loads over long distances. Dual rope-guide design allows horizontal or upward rope exit; SEW industrial geared motor provides quiet, efficient drive; electromagnetic brake supports precise stopping. Rated 8000 kg with rope length up to 500 m. VFD speed control with wireless and wired operation.

Quick Specs

Rated load: 8000 kg (8 t)
Motor: 11 kW VFD motor with brake
Rope: Ø18 mm anti-twist, up to 500 m
Drive: SEW industrial geared motor
Rope exit: horizontal / upward (dual rope-guide)

Application Scenarios and Applicable Boundaries

- Long-distance lifting & pulling — lifting or pulling heavy loads over extended rope travel (up to 500 m), reducing the need for repositioning.
- Horizontal & upward rope exit duties — dual rope-guide design adapts to installations requiring horizontal or upward rope outlet.
- Heavy equipment handling — 8-ton class lifting and pulling at construction, industrial and infrastructure sites.
- Continuous traction — VFD speed control (5.6–9.3 m/min) supports adjustable-speed pulling for different working scenarios.

Boundary: The standard configuration is not intended for personnel lifting. Confirm the load, rope, duty cycle and environment before ordering.

Features Benefits

8-ton carrying capacity — Supports lifting and pulling of heavy loads, covering most industrial lifting and traction duties.
Long rope travel — Rope length up to 500 m supports long-distance lifting and pulling, reducing downtime for repositioning and improving working efficiency.
Flexible rope exit — Dual rope-guide design allows horizontal or upward rope exit, adapting to different working scenarios and improving operational flexibility.
Quiet, efficient drive — SEW industrial geared motor provides low-noise, efficient power transmission, reducing noise impact and improving working efficiency.
Precise stopping — Electromagnetic braking supports more precise stopping and holding, improving control during lifting and pulling duties.

Complete Technical Specifications

Size Installation and System Interface

The winch is supplied on a high-strength welded base with lifting eyes and pre-drilled mounting holes for floor fixing. Overall dimensions, rope exit direction (horizontal or upward) and mounting orientation are confirmed on the general arrangement drawing after configuration approval.

Available interfaces include: motor power terminals, VFD control, wireless handle, wired control, electromagnetic brake control, encoder and main-shaft limit switch (optional), and slip ring (optional). Electrical interfaces are defined in the final wiring diagram.

Control Safety and Protection

- Normal control: VFD speed control with wireless handle and wired control; frequency knob on the control terminal for flexible adjustment.
- Stopping & holding: electromagnetic brake supports precise stopping and holding; stop behavior confirmed in the control scheme.
- Travel protection: limit switch and encoder (with main-shaft limit switch) available as options for defined travel.
- Rope protection: dual rope-guide supports horizontal or upward rope exit; inspect rope condition per the manual.
- Environment: confirm enclosure rating, temperature range and site conditions before ordering.

Standard vs optional items are confirmed on the control scheme for each order.

Customization Options and Engineering Process

Configured around your operating conditions — Share the required line pull, rope travel, operating speed, duty cycle, power supply, installation envelope and environment. KLD will review the application and provide a proposed configuration, technical drawing and quotation for approval. Free design schematics are provided for different scenarios.

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. Classification certificates (e.g. LRS / BV / ABS / DNV GL) can be arranged as an optional item for marine applications.

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

Engineering Cases

Challenge: A project required repeated lifting and pulling of heavy loads over long distances, with both horizontal and upward rope exit at the work site.
Solution: A heavy-duty traction winch (8-ton class) with dual rope-guide, SEW geared motor, electromagnetic brake and VFD speed control, configured for the required rope length and control mode.
Outcome: The winch passed the customer's functional acceptance procedure for the planned lifting and pulling duties.
