Rocker arm. A rocker arm (in the context of an internal combustion engine of automotive, marine, motorcycle and reciprocating aviation types) is an oscillating lever that conveys radial movement from the cam lobe into linear movement at the poppet valve to open it.hen the camshaft lobe raises the outside of the arm, the inside presses down on the valve stem, opening the valve. When the outside of the arm is permitted to return due to the camshafts rotation, the inside rises, allowing the valve spring to close the valve.
Single/sliding arm lifts have either one arm in a fixed position or one fixed and one sliding arm. A single/sliding arm lift reduces the lifting capacity to only 600 pounds. However, it enables the handicap lift to move out of the way of a non-wheelchair user when it is not in use. Another benefit of single/sliding arm wheelchair lifts for vans is that the front passenger seat can move and tilt back unaffected.
