bergen-power constant support 98c
DESCRIPTION
Our constant spring hanger incorporates a design that generates a constant supporting force throughout its total travel range. The design, using a compression spring, a lever, and a spring tension rod, creates a moment counterbalancing about the main pivot pin. This concept utilizes the principle of a varying leverage about a main pivot that compensates for the varying spring force as the lever travels from the high to the low point or from the low to the high point.TRANSCRIPT
