Aluminum Alloy Lightweight Winch 250kg with Hand Crank | KLD

A compact, portable winch with an all-aluminum body for lighter self-weight and easier handling. Right-angle geared motor with electromagnetic brake, reciprocating lead-screw rope guide for orderly winding, and a manual hand crank for emergency use. Rated line pull 250 kg, 20 m rope length. Speed, voltage and options are configurable.

Quick Specs

Rated line pull: 250 kg
Rope length: 20 m (configurable)
Motor: 0.4 kW right-angle geared motor
Rope speed: 6 m/min (average)
Emergency drive: manual hand crank

Application Scenarios and Applicable Boundaries

• Portable & temporary jobs — lifting and pulling duties where the winch must be moved between positions; the lightweight aluminum body makes transport and setup easier.
• Maintenance & repair — hoisting tools, components or materials during equipment servicing in workshops or on-site.
• Small hoisting & positioning — controlled lifting and lowering of light loads at low speed, with orderly rope winding supported by the lead-screw guide.
• Emergency & power-outage situations — the manual hand crank allows the winch to be operated without electrical power for limited emergency use.

Boundary: The standard configuration is not intended for personnel lifting or for loads exceeding the rated line pull. Confirm the load, duty cycle and environment before ordering.

Features Benefits

-Lighter self-weight, easier handling — The all-aluminum body reduces overall weight compared with steel-frame equivalents, making the winch easier to carry, position and install for portable applications.
-Compact, stable drive — The right-angle shaft geared motor integrates the reduction stage into a compact unit, supporting stable low-speed operation in a space-saving layout.
-Holding on power-off — The electromagnetic brake provides holding when power is removed, supporting safe parking of the load under long-term load conditions when the winch is correctly operated and maintained.
-Orderly rope winding — The reciprocating lead-screw guide moves the rope evenly across the drum during winding, helping maintain consistent rope layers and reduce loose winding when correctly installed.

Size Installation and System Interface

The winch is supplied on a base plate with pre-drilled mounting holes for fixing to a floor, frame or platform. Overall dimensions, mounting orientation and rope exit direction are confirmed on the general arrangement drawing after configuration approval.

Available interfaces include: motor power terminals, optional limit switch contacts, hand pendant or wireless remote control (optional), and guide pulley sets (optional). Electrical interfaces are defined in the final wiring diagram.

Control Safety and Protection

• Normal control: direct-on-line start as standard; speed and control options (pendant, wireless remote) configurable.
• Holding: electromagnetic brake provides holding when power is removed, supporting parking under long-term load conditions; brake performance is confirmed during configuration review.
• Travel protection: mechanical limit switch available as an option for defined stop positions.
• Emergency operation: manual hand crank allows limited operation without electrical power.
• Environment: aluminum alloy body suitable for indoor and outdoor dry-duty use; confirm temperature range and exposure before ordering.

Standard vs optional items are confirmed on the control scheme for each order.

Customization Options and Engineering Process

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 holding function and control verification. Available documentation may include dimensional drawings, electrical diagrams, inspection records and functional test results, depending on project scope.

Engineering Cases

Challenge: A manufacturing site required a portable winch for routine maintenance lifting that could be moved between workstations, with a backup means of operation during power loss.
Solution: An aluminum alloy lightweight winch (250 kg class) with electromagnetic brake, reciprocating lead-screw rope guide and emergency hand crank, configured to the site voltage.
Outcome: The winch passed the customer's functional acceptance procedure for the planned maintenance duties.
