MONORAIL FRAME

The main frame of an existing large haul truck is often the component that determines the lifetime of the vehicle. Large forces are transferred to the frame due to road impacts and shocks during loading. ETF developed an innovative solution: the Monorail frame. Instead of a frame on top of the axles as in competitive vehicles, the ETF frame is between the axles. Existing vehicles have four points on which the total load is transferred to the wheels. ETF’s monorail and axle system has ten points on which the load is transferred to the wheels. In this way the forces to the frame are better equalized. This monorail construction in combination with the long suspension travel reduces frame fatigue, resulting in extended life.

Lowest Centre of Gravity in the industry
Over 60 % of the vehicle weight is mounted lower than 1,500 mm from the ground. Due to the monorail frame, the loading height of the ETF truck could be limited to approx. 4,400 mm; this is at least 600 mm lower than competitive trucks. Both facts result in the lowest centre of gravity and therefore loading height in the industry.

High stability during driving enables higher speeds, resulting in shorter haul times.
