Meritor WABCO has included auto lift axle control and tire inflation data management into its newly released Rollover Stability Support (RSS) 1M trailer stability control system. These features control and monitor ancillary trailer components alongside the trailer rollover mitigation functionality of the system.
RSS 1M is a two-sensor, one-modulator system that not only offers the benefits of both ABS and trailer stability control integrated into a single compact unit, but also is capable of linking with a variety of trailer components. The RSS 1M is derived from the proven RSS 2M system, which has been available to fleets for nine years.
These two new features were previously only available on Meritor WABCO’s RSS 2M system that is widely utilized in the tank fleet market. Now, with this RSS 1M added functionality, the company can also support demand for these safety features in flatbeds, reefers and livestock trailers.
In addition to the potential safety benefits of the RSS technology, Meritor WABCO has added an automatic lift axle control to the RSS 1M to address customer demand. The system will automatically raise and lower the lift axle control based on the load of the trailer, allowing for better fuel economy and reduced tire wear.
Tire inflation data management, on the other hand, is achieved by linking the RSS system to the trailer’s tire inflation system. It monitors the tire and broadcasts an alert telematically in the event of tire pressure loss, thereby notifying the fleet operator of the tire’s condition.
Retrofit kits for RSS 1M are available to support air and spring suspension systems on fleets of any size. The tank-mountable kit addresses previous retrofit issues by providing for trailers of any make and those without fitted Anti-lock Braking Systems (ABS).
Meritor estimates the average rollover cost per trailer — excluding spills — ranges from $197,000 for property damage to $1.1 million if the incident results in a fatality. Rollovers are often considered one of the most serious incidents involving trailers, representing an average of 9 percent of all large truck and trailer crashes.
