Dump Trucks | Everything You Need to Know About Dump …
Kefid · A super dump is a straight dump truck equipped with a trailing axle, a liftable, load-bearing axle rated as high as 13,000 pounds. Trailing 11 to 13 feet behind the rear tandem, the trailing axle stretches the outer "bridge" measurement, the distance between the first and last axles, to the maximum overall length allowed.

Influence of long-waved road roughness on fatigue life of
Asymmetrical long-waved road unevenness can accelerate the fatigue failure of the dump truck frame. Due to the difficulty of the tire damping modelling and the complex pitch motion of balanced suspension, it is hard to reveal the relationship between the parameters of long-waved road and the fatigue life of dump truck frame. Firstly, on the premise of not introducing truncation error, …
