Dual Motor PLC Winch with Redundant Safety

Engineered for duties that need two independently controlled ropes from one winch. Twin right-angle geared motors with electromagnetic brakes, a spring rope presser for tidy winding, and a worm-gear height limiter with encoder for defined travel. Rated line pull 100 kg. PLC control and automation options available.

Quick Specs

Rated line pull: 100 kg
Motors: 2 × 1.1 kW (independent control)
Rope speed: 4 m/min (average)
Rope: Ø6 mm, 5 m + 3 wraps
Control: PLC (available) + encoder + height limiter

Application Scenarios and Applicable Boundaries

- Oilfield & petroleum equipment — lifting and positioning duties at equipment assembly, installation and maintenance sites, where two independently controlled ropes support balanced or sequential operations.
- Dual-point independent control — two ropes driven separately from one winch for applications requiring independent positioning of two points.
- Precision positioning — encoder feedback with worm-gear height limiter supports defined upper/lower travel and accurate positioning in automated sequences.
- Automated integration — PLC control of rope payout length increases automation in repeated industrial operations.

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

Features Benefits

1.Two ropes, independent control — Two motors drive the drum system and can be controlled independently, supporting balanced, sequential or differential operations from a single winch unit.
2.Quiet, high-torque drive — The right-angle shaft geared motors deliver high torque in a compact layout with low-noise operation, suited to repeated industrial duty.
3.Holding on power-off — The electromagnetic brakes provide holding when power is removed, supporting safe parking of the load under long-term load conditions when the winch is correctly operated and maintained.
4.Tidy rope winding — The spring rope presser keeps tension on the rope during slack conditions, helping maintain orderly layers and reduce tangling when the winch is correctly set up.

Size Installation and System Interface

The winch is supplied on a flanged base with pre-drilled mounting holes (4 × Ø13 mm) for floor fixing. Overall dimensions, rope exit direction and mounting orientation are confirmed on the general arrangement drawing after configuration approval.

Available interfaces include: dual-motor power and control terminals, electromagnetic brake control, encoder signal output, height limiter contacts, PLC communication and optional wireless remote. Electrical interfaces are defined in the final wiring diagram.

Control Safety and Protection

- Normal control: dual-motor independent control; PLC control of rope payout length available for automation.
- Position control: encoder feedback with worm-gear height limiter for defined upper/lower travel.
- Stopping & holding: electromagnetic brakes provide braking on stop and holding when powered down; stop positions defined in the control scheme.
- Protection: limit contacts and load monitoring confirmed per project; emergency-stop logic per the final control scheme.
- 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 and diameter, 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 3D design models 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.

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.

Engineering Cases

Challenge: An oilfield equipment manufacturer needed a compact winch with two independently controlled ropes for positioning duties during assembly and maintenance, with defined travel and position feedback.
Solution: A dual-motor winch (100 kg class) with right-angle geared motors, electromagnetic brakes, spring rope presser, worm-gear height limiter and encoder, configured for the required rope arrangement and control.
Outcome: The winch passed the customer's functional acceptance procedure for the planned positioning duties.
