Ken-Tool's Tire Restraining Devices Meet Safety Standards for Higher Inflation Level
May 2, 2013 - Products
Ken-Tool announced the company’s line of 2- to 7-bar tire inflation restraining devices (cages) are tested and now certified to address higher, 130-psi inflation pressure levels.
This new pressure level certification was prompted by the introduction of the 455/55R22.5 load range M truck tire, which is rated up to 130-psi inflation pressure. This tire and wheel configuration are growing in popularity for drive and trailer axles, replacing dual wheel/tire combinations.
The Occupational Safety and Health Administration’s O.S.H.A. Standard No. 29 CFR Part 1910.177 requires that inflation restraining devices contain 150% of a tire’s rated inflation pressure during a failure. To verify the ability of the cage to absorb the energy released during failure, Ken-Tool tested a truck tire on a multi-piece wheel at 195-psi.
Ken-Tool has posted a video to YouTube, which demonstrates the testing process.
The company is printing new warning labels in English and Spanish to reflect this change for its new and existing cages.
Ken-Tool products are available through tire industry supply distributors worldwide.
