TMS Shown to Work with Chained Tyres

AM Bromley, which manufactures a direct tyre pressure and temperature monitoring system for the OTR tyre market called TMS, has reportedly tested its product on chained tyres run by Chilean mining service company Bailac. According to the company, the results show that TMS will work within chained tyres and the system will continue to deliver tyre pressure and temperature data irrespective of the presence of the chains.

Mandy Bromley, director of TMS manufacturer AM Bromley said: “Maintaining the correct inflation pressure for a working earthmover tyre is the single most important means of maximising tyre life. Loader front tyres have been chained to reduce damage to the tyres, the environment means that valve mounted pressure sensors are exposed and risk damage. Until these tests it had been thought that the chains would act in a similar way to a Faraday cage and prevent the sensor from transmitting the readings to the operator interface inside the cab. The tests prove that TMS can now be used with chained tyres.”

The results are said to be particularly important to operations running radial tyres where good pressure control is particularly critical. Under inflated radials are prone to bead turn-up and belt edge separations leading to early tyre failure. Furthermore, bead damage due to under inflation means that a re-tread will not be possible nor would a major repair. And with AM Bromley reporting that tyres typically account for 25 – 30 per cent of haulage operating costs in quarries and open pit mines and site tyre life varying by 30 per cent or more depending on pressure maintenance the figures are likely to attract serious consideration.
