Hydropower Cable Winch with Encoder Slip Ring

A cable winch purpose-built for hydropower stations, supporting safe and reliable cable winding. A 12-way alloy slip ring (IP65) transfers signal and power through the rotating drum; an integrated limit encoder enables automatic control; a right-angle geared motor delivers quiet, efficient drive; and a lead-screw rope guide with roller array keeps cable winding orderly and avoids abrasion.

Application Scenarios and Applicable Boundaries

- Hydropower station cable handling — cable winding and payout duties where a vertical frame suits the station layout.
- Long vertical runs — rated for 500 kg lifting with 2.5–2.9 m/min rope speed and 30 m drum capacity (case).
- Signal & power transfer — 12-way alloy slip ring passes signal and power through the rotating drum.
- Automatic control duties — integrated limit encoder supports automatic control; VFD control panel optional.

Boundary: Cable diameter and drum capacity are matched to the application. Standard configuration is not intended for personnel lifting. Confirm cable diameter, run length, load and site environment before ordering.

Features Benefits

Quiet, efficient drive — the right-angle geared motor provides quiet operation with efficient transmission.
Automatic control ready — the integrated limit encoder supports automatic control of the winding process.
Signal & power through rotation — a 12-way alloy slip ring rated IP65 transmits signal and power while the drum rotates.

Control Safety and Protection

- Integrated limit encoder plus built-in motor encoder — precise control of motor speed and position, improving winding accuracy and stability.
- 12-way alloy slip ring (IP65) — signal and power transfer through the rotating drum.
- Roller array rope guide — helps prevent cable abrasion and keeps winding orderly.
- Optional safety & control: upper/lower limit switch, encoder with main-shaft limit switch, slack-rope switch, VFD control panel, class certificates (LRS/BV/ABS/DNV GL) on request.
- Personnel lifting is excluded from standard configurations.

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.
