4" Anti Runaway Chain Device, Part # 101878

Details Designed for 4” I-beam systems, this anti-runaway device is installed on the decline portion of a vertical curve. Increased chain speed from chain failure causes the trolley to impact the stop arm with sufficient force to rotate the shank 180° into the actuated position, thus stopping the next trolley.
