Hand Crank Dual Speed Winch 800kg Portable | KLD

A portable, dual-speed hand winch for lifting, pulling, winding and fixing duties where no power supply is available. Two gear ratios — 2X fast for quick line retrieval, 1X slow for high torque under load — with a worm gear drive and maintenance-free right-angle transmission. Rated load 800 kg. Driven by manual crank or compatible electric/pneumatic tools.

Quick Specs

Rated load: 800 kg
Gears: 2X fast (quick retrieval) / 1X slow (high torque)
Drive: manual crank / electric or pneumatic tools
Duty class: M4
Machine weight: approx. 30 kg

Application Scenarios and Applicable Boundaries

- Sites without power — lifting, pulling and fixing duties in field work, construction, utility and outdoor operations where no electrical supply is available.
- Maintenance & repair — winding, tensioning and pulling of ropes, cables or small loads during equipment servicing.
- Warehousing & workshops — tensioning and positioning of loads, gates, screens or small carriages.
- Stage, exhibition & rigging — manual pulling and winding where portable equipment is required.

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 2X fast gear retrieves rope quickly when unloaded, while the 1X slow gear provides higher torque with less effort under load, letting one winch handle both quick winding and heavy pulling.
Flexible drive options — The hexagonal input shafts accept a manual crank, electric drill or pneumatic tool, allowing operation by hand or with commonly available power tools.
Flexible drive options — The hexagonal input shafts accept a manual crank, electric drill or pneumatic tool, allowing operation by hand or with commonly available power tools.
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 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; optional rope guide, limit switch, compression roller and brake can be fitted per application.

Control Safety and Protection

- Gear selection: 2X fast for unloaded retrieval, 1X slow for loaded pulling; select the gear per the operation manual.
- Drive control: manual crank or power-tool drive; speed is controlled by the operator.
- Load protection: rated load and duty class (M4) per the nameplate; do not exceed the rated load.
- Optional protection: limit switch, compression roller and brake available as options.
- Mounting safety: confirm mounting surface strength and fixings per the manual.

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. 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, 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 field operation site had no electrical supply and needed a portable winch for occasional lifting and rope tensioning duties.
Solution: A hand-cranked dual-speed winch (800 kg class) with fast/slow gears and power-tool drive compatibility, mounted for the site's installation conditions.
Outcome: The winch passed the customer's functional acceptance procedure for the planned duties.
