Winch Rated Line Pull
This is the rated line pulling capacity that a single line can handle safely without the use of a snatch block or other device. This is measured on level ground pulling dead weight (not rolling weight) from the first layer of cable on the drum. The line pull on any layer that results from the output torque which produces maximum rated line pull on the first layer. Rated first layer line pull is based on maintaining an acceptable structural safety factor while providing an acceptable component service life. Line pull is expressed in pounds or kilograms.
