On level ground using skids and rollers, what percent of the weight of the load should yield the required line pull as a general rule of thumb?

In rigging applications on level ground using skids and rollers, the general rule of thumb is that 5% of the weight of the load is typically sufficient to achieve the necessary line pull. This percentage takes into account the friction between the load and the ground, as well as the efficiency of the skids and rollers being used. When skids or rollers are employed effectively, they significantly reduce the frictional forces at play, allowing for ease of movement.

This rule helps ensure that riggers can estimate the required force needed to move heavy loads safely and efficiently without the risk of overloading the equipment or straining the rigging setup. The selected percentage is a balance that considers both the physical properties of the surface and the mechanics involved in moving heavy objects, making it a useful guideline for riggers working in various environments.
