TyrePal is launching a new tyre pressure monitoring system (TPMS) to help OEM trailer builders and trailer fleet operators tackle the problem of tyre blowouts on HGV freight trailers.

The TyrePal trailer TPMS indicator consists of TyrePal sensors on each tyre and an indicator that can be mounted inside or outside the trailer.

The indicator can operate independently of the truck to provide an immediate visual and audible alert when the sensors report rapid pressure loss, tyre overheating, under-inflation or over-inflation.

"Due to the weight distribution and design of HGV trailers, especially double-decker trailers, if tyres pick up slow punctures, they often go unnoticed until it is too late," explains Peter Tilliotson, business development manager of TyrePal.

"When the improperly inflated tyre is forced to work, it heats up and can cause blowouts. This leads to downtime and risks hazard to the driver and other road users. Apart from being very unsafe it will also increase fuel usage significantly."

The device operates on an internal battery - automatically recharged when power is available, either from the trailer supply or by connection to the trailer lights.

When the trailer is not in use, the indicator goes into a sleep mode and automatically turns back on when there is any vibration, for example the opening of trailer doors. This means that it can remain on standby for up to 10 weeks on a single charge.

The system can communicate with a TyrePal TeleTPMS module to provide complete on-line monitoring of the trailer from the fleet office, including full GPS tracking. This allows fleet managers to track their vehicles and monitor tyre pressure remotely.

TyrePal will be on stand 4K50 at the Commercial Vehicle Show.
