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
T
HE CABLE FASTENERS ON THIS OR ANY WINCH ARE NOT
DESIGNED TO HOLD RATED LOADS INDEPENDENTLY . A LWAYS LEAVE A MINIMUM OF FIVE
