Longer Wear Life
Originally developed for hard rock mining, the rubber wear mat (Floor) has proven to last over 20,000 hrs of operation (wear can be further extended under more moderate conditions). |
Very Low Maintenance
Duratray Bodies are virtually free of maintenance. As well, replacing the rubber wear mat takes a fraction of the time when compared to relining plates on traditional Steel Dump Bodies. |
Elimination of Carry Back
The Duratray Dump Body is the only solution for transporting sticky material. Dirt or clay will not stick (or in cold climates freeze) to a surface that continually stretches and flexes during loading and unloading, thus preventing any material from building up. Hang up or carry back is practically eliminated. |

Increased Payload
Compared to an equivalent standard steel lined body, Duratray’s body weighs substantially less. In addition, the unique suspension systemallows for significant gains in load volume
