SMI supplies hand crank trailer winches in standard configurations and fully customised specifications — manufactured from heavy-duty carbon steel with zinc-plated finish for corrosion resistance and long service life. Standard capacity range covers 1,200 lb to 3,500 lb, with custom load ratings, drum dimensions, cable length and material configurations available to meet specific application requirements.

Winch supply is one part of SMI’s broader capability in mechanical components and OEM manufacturing — a capability with established market presence in the United States and Japan. Custom configurations are available for OEM customers requiring specific dimensions, load ratings, surface treatments or cable/strap specifications.

Standard Features

Construction

Heavy-duty carbon steel body with zinc-plated finish — resistant to corrosion and suitable for outdoor and marine-adjacent environments. Solid construction designed for repeated load cycles in trailer, marine and industrial handling applications.

Capacity Range

Standard range: 1,200 lb to 3,500 lb cranking capacity. Custom load ratings outside this range are available — please specify required working load and safety factor at enquiry stage.

Two-Way Ratchet Mechanism

Fitted with a sturdy safety pawl allowing forward and reverse ratcheting. The ratchet mechanism prevents load slip during cranking and holds the load securely when the handle is released.

Cable or Wire Rope Options

Available with steel wire rope or webbing strap configurations depending on application. Cable length and diameter are customisable. Hook and attachment hardware included as standard.

Weight Distribution & Sway Control System

A weight-distributing hitch is a “load leveling” hitch. It is a hitch setup mounted on the tow vehicle that uses spring bars and chains under tension to distribute part of the trailer’s hitch weight from the towing vehicle’s rear axle to the towing vehicle’s front axle and to the trailer’s axle(s). It can help reduce trailer sway and hop. Trailer hop can jerk the tow vehicle. Trailer sway is sometimes called “fish tailing”. At high speeds, trailer sway can become dangerous. Most vehicle manufacturers will only allow a maximum trailer capacity of 5,000 pounds (2,300 kg) and 500 pounds (230 kg) of tongue weight without using a weight-distributing hitch. Tow vehicles often have square receiver sockets to accept weight distributing hitches.

Let us know your detail demands and inquiry now.

A tow hitch (or tow bar) is a device attached to the chassis of a vehicle for towing, or a towbar to an aircraft nose gear. It can take the form of a tow ball to allow swiveling and articulation of a trailer, or a tow pin, or a tow hook with a trailer loop, often used for large or agricultural vehicles where slack in the pivot pin allows similar movements. SMI(Sino Machine Industry) towing pintle used worldwide.
