Abstract
A lift assembly including a lifting structure, a lifting arm, a yoke structure fixed to the lifting structure, a pin pivotally coupling the lifting arm with the yoke structure, and an integrated anti-rotational assembly associated with both the yoke structure and the pin. The lifting structure can actuate relative to the ground between a lowered position and a raised position. The lifting arm is configured to actuate with the lifting structure between the lowered position and the raised position. The integrated anti-rotational assembly can inhibit rotation of the pin relative to the yoke structure about the longitudinal axis of the pin.
