The Japanese manufacturer of construction, mining, forestry and military equipment Komatsu recently approved the Continental EM-Master tires (Figure 1), both in E3/L3 and E4/L4 version for use in applications with different ground conditions. Starting January 2020, customers in Europe are able to select the Continental radial tires in the sizes 20.5 R25, 23.5 R25, 26.5 R25 or 29.5 R25 if they buy one of the Komatsu Dash 8 Wheel Loader Series (WA270-8, WA320-8, WA380-8, WA470-8, WA-480-8, WA500-8).
Continental’s EM-Master is tailored to the needs of construction sites and mining sites where articulated dump trucks, wheel loaders and dozers are used. The EM-Master E3/L3 has a normal tread depth and a larger distance between the tread blocks for good self-cleaning properties, traction and maneuverability even on soft and muddy ground. The open tread pattern design ensures better cooling properties and thus lower heat build-up, resulting in higher mileage.
Compared to the E3/L3, the EM-Master E4/L4 has a larger block size with a smaller gap between the blocks. The tire therefore offers high carcass protection and good cut resistance, reducing the risk of punctures and thus downtime. The smaller spacing of the tread blocks with the five-edged block design ensures smoother running and good traction even on hard and rocky surfaces. Due to its high tread wear volume, the EM-Master E4/L4 also offers a high mileage.
The EM-Master is equipped ex works with integrated tire sensors. The sensor continuously monitors pressure and temperature of the tire. With the help of the tire pressure monitoring systems ContiPressureCheck for individual vehicles and ContiConnect for vehicle fleets, the data can be monitored and displayed. This maximizes uptime, reduces downtime and increases operational efficiency. At the same time, the systems also increase vehicle safety.
