Device for the purpose of preventing a body depending from ropes from swinging
First Claim
1. A device for raising and lowering a load while preventing swinging of the load, said device comprising a container bridge, a trolley displaceable on said bridge, a drum on said trolley, sheaves on said drum and on the load to be raised and lowered, hoisting cables extending from said sheaves on said drum to the sheaves on the load for lowering and raising the load by pay-out and wind-up of the cables, and means for preventing swinging of the load comprising at least one positioning wire connected to said trolley for being paid-out and wound-up, one end of said positioning wire being secured to said load such that said wire extends obliquely upwards therefrom at an angle with respect to said hoisting cables, and a further drum on said trolley, the other end of said positioning wire being attached to the further drum on the trolley to pay-out and wind-up the positioning wire to a smaller extent than the hoisting cables such that the load is raised and lowered along a path inclined with respect to the vertical.

Abstract
A device for raising and lowering a load while preventing swinging of the load comprising a container bridge having a displaceable trolley thereon, the trolley carrying a drum for hoisting cables which pass over sheaves to the load for raising and lowering the load by wind-up and pay-out of the cables. In order to prevent swinging of the load, a positioning wire extends from a drum on the trolley to the load at an oblique inclination which forms an angle with respect to the hoisting cables.
