Continental Commercial Specialty Tires (CST) recently presented two new tyre solutions for off-the-road applications (OTR): the Conti EM-Master E3/L3 and E4/L4 as well as the Conti RDT-Master E4. The tyres are “customised for the specific demands in the construction and earthmover segment. The newly developed tread pattern designs make each solution a perfect fit for different environments, ranging from soft, muddy soil to solid terrain. Regardless of the application conditions, both products offer excellent traction and high cutting resistance.”
With the introduction of the new OTR tyre products, Continental CST says it has enhanced its comprehensive specialty tyre portfolio and that this underlines its business ambitions in the construction but also ultimately in the mining sector. “The Conti EM-Master E3/L3 and E4/L4 and the Conti RDT-Master E4 are once more successful outcomes of our customised solutions strategy,” says Christian Luther, Product Line Manager Earthmover Tires at Continental CST. “In view of our expansion strategy 2025, we will continue to expand and optimise our product and service portfolio in the segment of construction and mining in the course of the coming years.” The first tyres will be available at the end of 2015. Further sizes and tyre solutions are planned for 2016 and beyond.
The Conti EM-Master is available in two versions “which are each perfectly tailored for the specific demands in OTR applications.” The Conti EM-Master E3/L3 is especially suited for application in muddy and soft terrain, while the Conti EM-Master E4/L4 “is an excellent option for use in gravelly and rocky grounds.” The reason is that both tyre solutions offer different tread design features. The Conti EM-Master E3/L3 features a normal tread depth and wider spacing of blocks than the Conti EM-Master E4/L4. This results in excellent self-cleaning characteristics, powerful traction, and good manoeuverability which facilitate the use in muddy terrain. The open tread design and normal tread depth (100%) of the E3/L3 tyre version further offers better cooling and therefore less heat buildup for a long service life.
Compared to the Conti EM-Master E3/L3, the E4/L4 tyre version features a greater block size with less spacing between the blocks and a deeper tread depth. “Therefore, the new tyre solution offers a higher carcass protection and superior cutting resistance, minimizing the risk of punctures and downtimes. The less tread block spacing also results in a smoother running even on hard surfaces.” Due to a high tread wear volume, the Conti EM-Master E4/L4 offers an even longer service life compared to the E3/L3. Both Conti EM-Master E3/L3 and E4/L4 will be available in the sizes 23.5R25, 26.5R25, and 29.5R25; the Conti EM-Master E3/L3 additionally also in the size 20.5R25. The tyres “are therefore perfectly applicable on articulated dump trucks (ADTs), loaders, and dozers.”
To increase the safety and efficiency of vehicle fleets in heavy-duty applications such as construction, quarrying, and mining, the ContiPressureCheck™ monitoring system can be easily mounted on both Conti EM-Master E3/L3 and E4/L4 and Conti RDT-Master E4. Due to automatic monitoring of the tyre pressure, the risks of puncture accidents are reduced which offers more safety for both driver and vehicle. “Correct tyre pressure further leads to lower energy consumption of the vehicles and to increased mileage capability. Fleet operators can significantly reduce their operating costs and increase the efficiency of their fleets by using ContiPressureCheck™. At the same time, the environmental impact is downsized, since CO2 emissions are reduced and the life of the tyre is extended.”
