The new Vigia internal automatic tire-inflation system can be installed on most trailer steering and lift-steering axles. Both dual and wide-base tires can be outfitted. Specifically developed for trailers, and said to be a first, the system delivers air to the tires through conduits inside the axle so no lines are externally visible. Rotating valves are placed outside the hubcap preventing water and other contaminants from entering the hub. Since pressurized air travels inside the lines, Vigia says there’s no pressure building inside the axle or hub, nor oil leaking out the hubcap.
Vigia’s offerings include dedicated systems for tractor-trailer combinations, trailer-only systems, and external or internal system connections. With the company’s new NM343 telematics control module, operators can access information on the status of the system in real time on any computer or mobile device. Managers can know that a tire is low in pressure even before the driver.
Vigia tire-pressure systems are claimed to “virtually eliminate” the need for road-service calls and expensive downtime. If a tire has been punctured, the system will continue to inflate that tire and, at the same time, let the driver know what’s happening.
