This new generation machine features a 4x4 driveline and offers better productivity as it now has rear suspension. This helps improve travel speed over rough ground while also reducing material spillage from the dumpbody, which has a standard capacity of 25m3 although a 26m3 variant with a tailgate is available. The firm says that the suspension system is similar to the design used on the firm’s 55tonne class machine, featuring a Kessler axle and two suspension struts. An anti-slip system and traction control also help improve performance on rough ground, while reducing wheel slip and tyre wear.
The new dumpbody design offers a payload of 41tonnes, pitching it against 45-50tonne capacity class rigid trucks, while this machine has the advantage of the 4x4 drive system. With all-wheel-drive, the B45E is better able to cope with the steep ramp hauls often seen on European quarry sites than comparable rigid dump trucks with only rear wheel drive.
Power comes from the same emissions compliant, 390kW Mercedes diesel as used in the six-wheel-drive version of the B45, with the key differences being the rear chassis and dumpbody design.
