Abstract
A lift truck employs forward and reverse pedals connected through respective cams having different upper and lower cam profiles that engage to provide asymmetric reciprocal pedal motion. For example, first pedal depression causes a first cam upper profile to engage with a second cam upper profile and cause increased elevation of a second pedal, and first pedal depression causes a first cam lower profile to disengage with a second cam lower profile associated with the second pedal, such that first pedal depression is greater than the increased elevation of the second pedal.
