ABSTRACT:
This anti-sway device uses roller chains to greatly restrict the lateral movement of the lifting lines suspended from hoists or cranes. The roller chain is suspended parallel to the lifting lines or lifting chains. One end is attached to the free end of the lifting lines. The other end of the roller chain is wound around a takeup reel which prevents the roller chain from going slack. Since roller chains tend to be very stiff in a direction parallel to the pivotal axes of the roller links, the roller chain will tend to prevent the lifting lines from moving in the plane of the pivotal axes of the roller links.
