Trailer Winch Hand 5:1 / 1:1 Ratio
5:1 / 1:1 Ratio
5:1 Ratio - 5 turns of the handle is one turn of the drum, however with the added advantage of a shaft on the other side also which allows 1:1 ratio to get the bulk of your wire wound on the drum when slack allows, then swap to the 5:1 ratio handle for the last bit that needs greater tension.
Decent quality NZ made galvanized casing and handle, the fastening area and casing is remarkably strong as this is constructed of box section style. Platform area required for mounting is 100mm wide x 140mm long (for'd/aft) minimum.
Ideal for where a small mechanical reduction is needed to perhaps pull a boat into a garage or caravan (on its wheels). The drum diameter is 20mm and a handle length of 190mm (centre of pivot to centre of handle grip, so basically a radius) creates a mechanical advantage, plus - 3 turns of the handle is one turn of the drum.
Height of winch approx 155mm, width including the two shafts that protrudes for handles 230mm.
Tired of hauling away, getting the winch wire jammed on your old hauling unit?
Supplied with handle.
