The Hendrickson Tire Inflation System (HTIS) option for Intraax and Vantraax trailer suspension systems maintains inflation to a specified level. This system detects low tire pressure and alerts the operator. It responds by directing air when a tire dips below a predetermined pressure level. HTIS activates only when needed.
With HTIS, air travels from the supply tank through air lines inside the axle to the wheel ends. A rotary union allows air to flow from a non-rotating axle spindle to the rotating hubcap fitting. Hoses connect from a hubcap tee to the tires. A warning light alerts the operator to system status and maintenance activity, and the system records episodes of low tire pressure for retrieval during servicing. Check valves help prevent tire pressure loss back through the system. Manual fill and pressure checks may be done at the hose end.
An addition to Hendrickson's Ready-To-Roll (RTR) options, HTIS connects all tires to the trailer air supply and may be combined with any of an array of wheel-end configurations and spindles available for Intraax and Vantraax.
