Foot Pedal Forces for Seated Operators

The foot controls of spot welding machines were orgonomicnlly evaluated, and redesign recammondations put forward. Ten male and ten female subjects were tested to dotermine the maximum isometric force that a seated operator could exert on a horizontal foot pedal. The experimental results showed no significant strength differences between right arid left legs and mole legs strengths were 9% to 50% greater than female leg strengths depending on the position of the foot pedal.
