UNIQUE AXLE SYSTEM AND CONFIGURATION (20x16x20)
In order to solve loss of production suffered by conventional haul trucks during heavy rain or snow, ETF designed an all new innovative truck incorporating all-wheel-drive, all-wheel-steer configuration, combined with advanced Anti Lock Braking and Traction Control.
Due to the sheer scale of this increased traction, ETF trucks can climb grades better as well as maintain full stability downhill loaded even during full ‘all wheel retarding’ on any surface and under any climatic conditions. As a result, mine operators will see increased machine utilization induced production in the order of 8 % without increased capital expenditure.
Compared to existing vehicles the ETF’s axle system and configuration is totally different.
Large Haul trucks have only two axles of which only one is normally powered. Articulated Dump Trucks have three axles of which two or three are powered.
ETF MT-240 trucks are equipped with ten axles and twenty wheels, all of which are steered and eight axles and sixteen wheels are driven. Therefore, ETF needs to rewrite some more engineering terms describing the configuration as 20x16x20 one that is completely unique in the industry.
Each axle-line consists of two oscillating axles. The oscillating angle is 10 degrees both ways. Combined with a suspension travel of 950 mm providing better stability, supreme road contact and optimal tyre load spread compared with the existing duel rear tyres of competitive vehicles.
Oscillating axles 10 degrees both ways ensures equal tyre loading, optimal traction and reduces spillage
