The lift assist spring is connected on a first end to the bottom side of the lip at the pivot point and connected on a second end to the frame. The assist bar is used to move the lip between the extended/engaged and retracted/disengaged positions. The dock leveler includes a bracket with a vertical portion and a horizontal portion, the horizontal portion is secured to the frame on a frame-end and secured to the vertical portion on free-end. The lip can rotate above and over the bracket when in an extended/engaged position; the lip contacts the horizontal portion when in the retracted/disengaged position acting as a safety barrier.
