In tough conditions such as those encountered on mining and construction sites, efficiency and safety are key. However, underinflated tyres are still a major cause of breakdowns and service calls, with on average, one third of fleet tyres underinflated. This not only has an effect on fuel consumption but also on the tyre life – with 10 percent underinflation, tread life is reduced by 15 percent and casing life by 20 percent. With 20 percent underinflation, casing life is reduced by up to 30 percent. Optimally used tyres and better conserved carcasses can be used for retreading and thereby give the tyre several lives. Verifying proper tyre pressure and temperature maximises uptime because the risk of breakdowns is reduced and scheduled maintenance no longer needed.
To ensure the correct tyre pressure and temperature, Continental has developed its digital tyre pressure monitoring system ContiPressureCheck. With the help of tyre sensors mounted on the inner liner of the tyre, the systems monitor, analyse and report data about tyre temperature and pressure, helping optimise fleet efficiency.
Constantin Batsch, Vice President Truck Tyres Replacement EMEA at Continental, says: “Ensuring the right tyre pressure optimises the fleet cost efficiency: by reducing fuel consumption, increasing uptime, maximising tyre life and ensuring casing value. We provide smart solutions, helping customers ready their construction fleet for a digital future, thereby saving money overall.”
Tyre sensors – making the tyre intelligent
Continental tyre sensors are at the core of ContiPressureCheck. The intelligent tyre sensors constantly measure temperature and pressure from inside the tyre and provide data to be displayed on the dashboard – whether this is on a handheld device, inside the driver’s cab, on a yard reader station or on a web portal overseeing the fleet. The alerts and notifications are designed to steer the fleet’s attention to any situation requiring immediate action.
For the new Conti CrossTrac truck tyre line, customers can select an intelligent tyre from a number of popular sizes, whereas all tyres in the OTR ContiEarth portfolio come as intelligent tyres with preinstalled tyre sensors shipped straight from the factory.
The ContiPressureCheck system displays the tyre sensor’s data in the driver’s cab or on the handheld device and warns before a condition becomes critical. It is a complete, driver-focussed solution for single vehicles and can also be integrated into third-party telematics solutions for 24/7 multiple vehicle monitoring. ContiPressureCheck has now been on the market successfully for five years and is available in 47 countries.
Proven solutions tested under severe conditions
ContiPressureCheck has successfully proven its value. For example, construction customer, BetonMastHæhre, the biggest road construction company in Norway, has shown a high level of satisfaction with both systems. They tested the solutions with the Continental EM-Master in a remote area of Northern Norway. After the test, BetonMastHæhre purchased several new 40-tonne ADTs with ContiPressureCheck integrated on the machine display screen.
While CEMEX in the UK has seen a fall of 43 percent in out-of-hours call outs for tyres, with the drivers identifying issues on route thanks to ContiPressureCheck. To prove its ability to withstand severe conditions such as extreme heat and speed, ContiPressureCheck has also been tested on the Russian KAMAZ-Master trucks during the Dakar Rally desert race.
