Electric Wire Flying Winch 250kg Servo Encoder Constant Torque Stage | KLD

An electric wire-flying winch built for stage and entertainment rigging. The servo motor drive with PLC programming enables coordinated control of multiple units; the grooved drum with wire rope clamp ensures orderly, directional winding; the built-in motor encoder allows digital setting of payout/retrieval length; constant-torque output and a touch-screen PLC interface support stable, efficient and safe operation.

Quick Specs

Rated tension: 250 kg
Motor: 3.7 kW servo
Rope: Ø6 mm, 52 m
Drum dia.: 107.14 mm | Rope speed: 61.93 m/min (avg.)
Encoder: built-in motor encoder (digital length setting)
Output: constant torque
Control: PLC programming, multi-unit synchronized control

Application Scenarios and Applicable Boundaries

- Stage & entertainment rigging — wire-flying effects and performer/equipment flying in theaters, shows and events.
- Coordinated multi-unit duties — PLC programming supports synchronized control of multiple winches for complex rigging.
- Precision length control — built-in encoder allows digital setting of winding/unwinding lengths.
- High lifting efficiency with reliable safety — constant-torque output suits frequent start/stop rigging operations.

Boundary: This winch is for rigging and load flying; personnel flying requires the complete rigging system design and is not covered by the standard winch configuration alone. Confirm load, rope, duty cycle and environment before ordering.

Features Benefits

Orderly directional winding — the grooved drum with a wire rope clamp ensures orderly winding and directional rope deployment, reducing operational errors and saving work time.
Precise digital length setting — the built-in motor encoder allows digital setting of winding/unwinding lengths, providing precise control for exacting operational requirements.
Stable, reliable operation — constant-torque output supports the winch's operational stability and reliability, enhancing efficiency and safety.

Complete Technical Specifications

Size Installation and System Interface

Outline dimensions (case): 710 × 550 × 358 mm (L × W × H).
Installation: heavy-duty frame with base mounting brackets; fixed or swivel base with optional pulley blocks (see Module 9).

Control Safety and Protection

- PLC programming — coordinated control modes for single or multiple winches; touch-screen interface for data reading.
- Built-in encoder — digital setting of winding/unwinding length for precise positioning.
- Constant-torque output — stable and reliable running for frequent start/stop rigging.
- Optional safety devices — overload protection (recommended per application), limit switches (per operational requirements), torque sensors (see Module 9).
- Personnel flying requires the complete rigging system design; not covered by the standard winch configuration alone.

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, limiter function and control verification. Available documentation may include dimensional drawings, electrical diagrams, inspection records and functional test results, depending on project scope.
