Digger derricks manufactured and tested to ANSI A10.31 are limited to their rated capacity on a maximum slope of what degree?

Digger derricks manufactured and tested to ANSI A10.31 are designed with specific safety and operational guidelines, one of which pertains to their rated capacity when working on slopes. The correct choice indicates that the rated capacity is limited to a maximum slope of 5 degrees.

This limitation is crucial because as the slope of the terrain increases, the stability of the digger derrick can decrease significantly. Operating on steeper slopes would raise the risk of tipping or losing control, which could compromise the safety of the operators and those in the vicinity. The 5-degree limit ensures that the equipment operates within a safe range where it can maintain its efficacy while minimizing the hazards associated with unstable ground conditions.

Understanding these operational limits is essential for performing safe work practices and ensuring compliance with safety standards in the field. When equipment is used beyond recommended parameters, not only do the risks increase, but so do the potential for accidents and injuries.
