Trailer Tips
Know your rolling weight
For safe and sure loading, Superwinch recommends following the car and trailer load chart below. Find the column that matches your percentage of slope or grade. Determine the slope by driving the amount of your ramp's rise by the ramp's length. Match the slope with the nearest weight of your car, always rounding up, and locate the corresponding winch Rated Line Pull (RLP)*. This guide is recommended for average vehicle rolling loads. Some applications may require larger winches than indicated.
Accessorize for safety
Maximizing winch safety and performance is as simple as attaching the proper accessories. Superwinch offers roller fairleads, recovery straps, gloves, and many more accessories designed for your special needs.
*RLP –
The weight the winch could pull perpendicular to the ground with a single line on the first layer of wire rope on the drum.
Car Trailers/ Rolling Weight
To convert lbs. to kg multiply by .4536
*A 10% grade is a rise of one foot in ten feet.
*Winches are not intended as a load securing device.
All ratings are based on the first layer of wire rope on the drum. You could experience a loss of up tp 13% pulling capacity per layer of wire rope (see example below).
Example of S5000 and the effect of each layer on Rated Line Pull (PLP) and rolling loads
Many of our units come standard with 50' of wire rope or more. In some cases this may be a disadvantage. Due to the length of your trailer you may be starting on the 3rd or 4th wrap. Simply shorten the wire rope to your needs. If you can work with 30', then shorten the wire rope and your performance will improve.
NOTE: To maintain electrical performance from the battery t the winch, we recommend dropping 3 wire sizes for every doubling of the length of the standard wire harness.
Example: No. 6 to No. 3 or 2 AWG.
