What to be aware of when selecting the right winch
The angle of inclination, friction factors and the weight of the boat are, among other things, important factors that influence the size / type of a suitable trailer winch
. In general, our experts assume a ratio of 2:1
. Meaning that for a boat weight of 1500 kg you would require a winch with 750 kg vertical tensile force. The weight / traction ratio can be improved to 2.5:1 - 3:1 if smooth-running trailer rolls
are being used. It might drop to 1:1 if you have to pull your boat across simple wooden blocks.
When in doubt and under harsh conditions (e.g. salt water), a simple rule applies: better choose the trailer winch one size bigger. Important:
Never use a crank-handle extension!
Our trailer winches are wire rope winches
that are supplied without wire
. You can supply the suitable wire rope or a wire / rope splice for you. Our product details assume a ratio of 2.5:1
