Cable Winch 300kg Composite Cable Rope Slip Ring Rope Guider | KLD

A cable winch built for airship ground testing as an umbilical winch. A composite cable rope carries both power and communication, which reduces the number of separate connections. Fitted with an electric slip ring, an automatic rope guider, a clutch device and a quiet motor. Case configuration: 300 kg rated pull, rope Ø6 mm × 300 m, 2.2 kW, rope speed 40–60 m/min.

Quick Specs

Model: 300 KG  |  Rated pull: 300 kg  |  Cable rope diameter: 6 mm  |  Rope length: 300 m
Motor power: 2.2 kW  |  Drum speed: 48.5 rpm  |  Rope speed: 40–60 m/min

Application Scenarios and Applicable Boundaries

- Airship ground testing — the case configuration is built for this duty: the composite cable rope carries power and communication to the airborne platform while the winch controls its height.
- Test benches that need power + signal to a moving load — the electric slip ring passes supply and signal lines while the drum rotates, so continuous rotation does not require a cable loop to unwind.
- Applications needing a quieter test environment — a quiet motor is specified to keep test-area noise down during high-speed running.
- Installations needing on-site manual intervention — a clutch device allows the rope guider to be adjusted by hand, and a hand wheel is provided (drawing item 24).
- Long rope runs — 300 m of Ø6 mm cable rope on a 711 mm single-plate reel.

Boundary: the case configuration is 300 kg rated pull, rope Ø6 mm, rope length 300 m, motor 2.2 kW, drum speed 48.5 rpm, rope speed 40–60 m/min, outline 960 × 799 × 1030 mm. This is a reference configuration. Before ordering, confirm: required rated pull, rope speed range, cable rope construction and conductor count, rope length and drum capacity, required power and signal channels through the slip ring, slip ring current/voltage rating and channel count, clutch requirement, control mode, power supply, duty classification and ingress protection.

Features Benefits

Automatic rope guider — lays the cable rope in order as it winds, which helps prevent tangling and disorderly spooling.
Composite cable rope — carries power and communication in a single line, which reduces the number of separate connections and the equipment's complexity, and helps lower the failure rate.
Electric slip ring — passes supply and signal lines through a rotating interface, which simplifies wiring and makes maintenance easier.
Quiet motor — designed to keep noise down while running at speed, which supports a quieter test area.

Size Installation and System Interface

Outline (case 300KG): A 960 × B 799 × C 1030 mm.
Reel: single-plate reel diameter 711 mm, reel length 430 mm (drawing).
Layout: side-plate construction — drum assembly between a motor-side side plate and a shaft-side side plate; side plates are the mounting/structural members.
Rope guiding: rope guider assembly (DSQZC-00-00-00) with a 16A chain drive (chain 54 links, driving sprocket 13T, driven sprocket 26T) inside a chain box; a guard plate  and chain box cover the drive.
Electrical interface: slip ring (purchased part) for power and signal transfer; confirm the required channels, current, voltage and speed limit.
Manual interface: hand wheel (purchased part) and a clutch device for manual rope-guider adjustment.
Lifting / handling: 4 lifting rings are listed in the assembly drawing for hoisting the unit.
Mounting: confirm the mounting interface, bolt sizes and the base detail on the approved drawing.

Control Safety and Protection

- Rope guiding: automatic rope guider with 16A chain drive, covered by a chain box and guard plate  — lays the rope in order and helps prevent tangling.
- Rope protection: cable rope guard ring — helps protect the rope from abrasion and helps keep it in position.
- Manual intervention: clutch device allows the rope guider to be adjusted by hand; a hand wheel is provided.
- Power / signal transfer: electric slip ring — passes supply and signal lines through the rotating drum.
- Quiet operation: quiet motor is specified to keep test-area noise down at speed.
- Recommended to confirm: upper/lower limit switches, slack-rope detection, overspeed protection, emergency stop, brake requirement, duty classification, ingress protection, earthing, and the slip-ring insulation and rating.
- Optional: drum divider flange, manual emergency crank, VFD control panel, pulley, encoder with main-shaft limit switch, pendant remote control, limit switch, rope follower, winding device, grooved drum, slack-rope switch, slip ring, class certificates (LRS / BV / ABS / DNV GL).

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

Reference: an airship test programme needed an umbilical winch able to raise and lower an airborne test platform while supplying it with power and communication over the same line. The test area also had to stay quiet during high-speed runs.

Solution: cable winch, case model 300KG — composite cable rope (power + communication in one line), electric slip ring for continuous power and signal transfer, automatic rope guider with 16A chain drive, clutch device for manual rope-guider adjustment, cable rope guard ring, quiet motor. Rated pull 300 kg, rope Ø6 mm × 300 m, motor 2.2 kW, drum speed 48.5 rpm, rope speed 40–60 m/min. Outline 960 × 799 × 1030 mm.

Outcome: the configuration matched the programme's lift height, power/signal and noise requirements, and passed acceptance.
