SPECIFICATIONS
Various load conditions affect winch performance. The line pull required for a
specific application depends on the weight of the load, condition of the trailer
rollers, and the degree of the loading ramp incline. The charts below are based
on a single line pull and provided as a guideline in calculating pulling capabilities.
WARNING THE CABLE FASTENERS ON THIS OR ANY WINCH ARE NOT
DESIGNED TO HOLD RATED LOADS INDEPENDENTLY. ALWAYS LEAVE A MINIMUM OF FIVE
WRAPS OF CABLE ON THE DRUM TO ACHIEVE THE RATED LOAD VALUES
