Laws of Physics govern the performance of a winch. Law #1: too many layers of rope on the drum will rob your winch of power and efficiency and keep you from working in the Pulling Power Zone™. |
 |
| |
WINCH INDUSTRY STANDARD Pulling capacity is determined by the load a winch can pull with only the BOTTOM LAYER of rope on the drum. |
| |
| |
3. |
Physics Law #2: double the line with a Pulley Block and double the pulling power of your winch. Removing extra rope from the drum to use with a pulley block not only doubles winch power, it allows you to work in the Pulling Power Zone™! |
