Abstract
A power box step on a vehicle having a safety arrangement that provides noticeable controlled failure of the power box step if damaged. The controlled failure is accomplished by using vertical and horizontal shear pins that are designed to break when the horizontal or vertical load applied to the step is too great. The failure of the step is controlled by vertical and horizontal movement limit pins that prevent the step from moving too far in the vertical or horizontal direction when failure occurs.
