In a Duratray Suspended Dump Body the steel floor and associated wear plates are replaced with a rubber mat which is suspended like a hammock above the steel framework by elastomeric transverse ropes. The suspended rubber floor in fact never rests upon the steel frame, and this is the concept behind the Suspended Dump Body and what gives Duratrays their 'life'.
The ability of the rubber mat to flex means that material simply cannot stick to the tray. Hang up of material is virtually eliminated.
The thickness and abrasive resistance of the rubber mat provides a wear life two to three times that of a lined steel body, whilst delivering up to a 20% weight saving/payload increase.
Furthermore, the ability to absorb loading shocks means greatly improved operator safety and comfort and reduced damage to the truck's chassis and instrumentation.
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).
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
SEVERE CLIMATIC CONDITIONS - ICE/SNOW
Unlike conventional bodies, Ice adhesion is non-existent on Suspended Dump Bodies. Hence, real operational advantages have been achieved at mines exposed to extremely low temperatures
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.
NOISE AND SHOCK REDUCTION
Reduction Of Loading Shock
The rubber wear mat and elastomeric suspension ropes provide damping and energy dissipating properties that almost totally absorb all loading impacts. This prevents impact shocks from transferring through the truck’s chassis and instrumentation, and more importantly, the operator.
Reduction Of Loading Noise
Loading noise is greatly reduced due to the shock absorbing properties of the Duratray Body. Operator health and safety issues involving noise exposure at quarry and mine sites continue to receive increased attention. In some cases where mines are located near towns, the ability to reduce ambient noise below a specified level has been the main reason for investing in Duratray Bodies.
Compared to an equivalent standard steel lined body, Duratray’s body weighs substantially less. In addition, the unique suspension system allows for significant gains in load volume.
