Abstract: Disclosed is an impact-reduction box through which the hoisting ropes of a mining shovel or other machine pass. The impact-reduction box includes a roller frame subassembly and spring box subassemblies attached thereto on either side. The impact-reduction box is configured so that when the hoisting cables impact the box during undesirable whipping, the roller frame subassembly will move in reaction while the spring box subassemblies will remain essentially motionless. The mining shovel will feel less of the impact of the jolting hoisting rope, and the rope will not suffer the wear and tear of frequent slapping against the machine such that the rope will be less likely to completely break.

Abstract: Disclosed is an impact-reduction box (10) through which the hoisting ropes of a mining shovel or other machine pass. The impact-reduction box includes a roller frame subassembly (12) and spring box subassemblies (30) attached thereto on either side. The impact-reduction box is configured so that when the hoisting cables impact the box during undesirable whipping, the roller frame subassembly will move in reaction while the spring box subassemblies will remain essentially motionless. The mining shovel will feel less of the impact of the jolting hoisting rope, and the rope will not suffer the wear and tear of frequent slapping against the machine such that the rope will be less likely to completely break.
