Duratray Body Benefits
Noise and Shock Reduction
 For me, this Duratray
Body is the best mining invention - Personally wish all trucks
carried Duratray Bodies! They absorb the shock of the loading
impact, not me - nor the truck. ... I do not want a steel
box no more!

Where operator health and safety is a concern,
or in operations where environmental noise pollution is expected
to be an issue, the use of SDBs should be evaluated.
