Open the CIPO recordAbstract From the Canadian patent
A tire cage is disclosed for containing the debris from a tire explosion. The cage includes a lightweight energy absorbing material for protecting structural members of the cage from tire explosion damage so that the cage is reusable. The energy absorbing material may be a metallic foam or other open celled structured material that is able to absorb large amounts of kinetic energy by permanently deforming. The cage is particularly effective in containing explosions of large equipment tires 6 to 12 feet in diameter and having a stored kinetic energy in a range of approximately 900 kilojoules to 1500 kilojoules.
