I have some knowledge of the Sumoglove Impact Reduction System. The Sumogloves are bonded to the end of the forktips, and offer a reduction in achieved impact forces on everything that forks can come into contact with. This would include Racking, however tests are being carried out in conjunction with the premier testing facility in the UK so as to be able to more accurately state what the likely reductions would be, and results will be published to industry. Put Sumoglove into Google and follow the links.
