Aluminum Cable Winch 50kg RV Worm Gearbox Auto Pay-out Encoder | KLD

A compact, lightweight all-aluminum cable winch for cable payout and recovery. The RV/R90 worm gearbox with self-locking holds the load without an external brake; a reciprocating lead-screw rope guide spools cable in orderly layers; a DC auxiliary motor enables automatic pay-out without external traction; a rotary slip ring allows external connection; and an encoder measures payout length. Fast, stable and safe for ships, docks, mines and construction sites.

Quick Specs

Rated load: 50 kg
Motor: 1.2 kW, 220 V

Machine weight: 40 kg
Dimensions (L×W×H): 536 × 758 × 526 mm

Application Scenarios and Applicable Boundaries

- Cable payout & recovery — controlled winding and payout of power or control cables.
- Ships & docks — cable handling on board and at berths.
- Mining & construction — field cable laying and recovery where light weight and mobility matter.
- Unmanned traction — the DC auxiliary motor supports automatic pay-out when no external pulling force is present.

Boundary: Rated load is 50 kg (case). Cable diameter and length are customized per application. The standard configuration is not intended for personnel lifting. Confirm cable diameter, length, load and site environment before ordering.

Features Benefits

Light yet rigid — an all-aluminum frame keeps the machine compact and light (40 kg case) while remaining structurally stable, and polyurethane swivel casters make it easy to move.
Self-locking drive — the RV/R90 worm gearbox (ratio 60:1) provides a compact, self-locking transmission that holds position without additional braking.
Orderly multi-layer winding — the reciprocating lead-screw rope guide spools cable in even layers, reducing overlap and tangle.
Automatic pay-out — a DC auxiliary motor supports smooth winding and payout of cable even when no external pulling force is present.

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, rope-guide function and control verification. Available documentation may include design drawings, electrical diagrams, inspection records and functional test results, depending on project scope.
