Heavy Duty Brake Hand Winch 5000kg Worm Gear 4-Way Rope Exit | KLD

A heavy-duty manual winch for lifting, pulling and positioning duties up to 5000 kg where no power is available. Dual-speed gears (slow for load, fast for retrieval) with a worm gear drive and brake for controlled stopping. Four-way rope exit (up/down/front/back) and front or side mounting. Driven by hand crank or power tools.

Quick Specs

Rated pull: 5000 kg (series 500–5000 kg)
Gears: 1X slow (load) / 2X fast (retrieval)
Transmission: worm gear + brake
Rope exit: 4 directions (up / down / front / back)
Drive: hand crank / power tools

Application Scenarios and Applicable Boundaries

- Floating & marine works — tensioning and positioning of floating bridge sections, pontoons and structures, where manual winches operate without site power and anti-corrosion coating is specified.
- Off-grid lifting & pulling — heavy lifting, pulling and positioning duties in field, construction and utility operations without electrical supply.
- Precise positioning — slow-speed, high-torque operation supports controlled placement of heavy components.
- Recovery & rigging — pulling loads, equipment or structures into position with a portable, high-capacity manual winch.

Boundary: The winch is manually or tool-driven; the standard configuration is not intended for personnel lifting. Confirm the load, rope and duty before ordering.

Features Benefits

Two gears for two duties — The slow gear provides high torque for controlled lifting and positioning under load, while the fast gear retrieves rope quickly when unloaded.
Smooth, controlled drive — Worm gear transmission provides high reduction and smooth operation, with a brake supporting controlled stopping and holding during positioning duties.
Rope exit in four directions — The rope can exit up, down, front or back, adapting to different installation and working positions without reconfiguring the winch.
Install where you need it — Front (horizontal) and side (vertical) mounting options support installation on floors, platforms or walls.

Complete Technical Specifications

Size Installation and System Interface

The winch can be mounted front (horizontal) on floors or platforms, or side (vertical) on walls using the front or side mounting holes on the base frame. Overall dimensions and mounting orientation are confirmed on the general arrangement drawing after configuration approval.

Drive interfaces include two hexagonal input shafts for manual crank or power-tool connection. Rope exit direction can be arranged up, down, front or back per the installation.

Control Safety and Protection

- Gear selection: 1X slow for loaded lifting/positioning, 2X fast for unloaded retrieval; select the gear per the operation manual.
- Stopping & holding: manual brake supports controlled stopping and holding during positioning duties.
- Drive control: manual crank or power-tool drive; speed is controlled by the operator.
- Load protection: rated pull and duty class (M3) per the nameplate; do not exceed the rated load.
- Rope protection: inspect rope condition and winding per the manual; rope exit direction per installation.

Standard vs optional items are confirmed for each order.

Customization Options and Engineering Process

Configured around your operating conditions — Share the required line pull, rope length, 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 design schematics 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. Classification certificates (e.g. 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, gear function and brake verification. Available documentation may include dimensional drawings, inspection records and functional test results, depending on project scope.

Engineering Cases

Challenge: A floating bridge project required 48 custom manual dual-speed winches for tensioning and positioning of bridge sections, with anti-corrosion coating for water-side service.
Solution: Heavy-duty brake hand winches configured per the project, with the customer-specified anti-corrosion coating and installation arrangement.
Outcome: The winches passed the customer's acceptance procedure for the planned tensioning and positioning duties.
