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.
Duratray offers the best solution for haul trucks to eliminate carry-back and freeze-up, improve wear resistance in highly abrasive mining conditions. It is the only provider in the market of the unique Suspended Dump Body (SDB) offering the durability to outlast and out-perform conventional steel bodies.
Duratray is also a well-known specialist in the design, engineering and commercialization of spare parts, steel and rubber components for mining haulage equipment. In addition, the company provides services such as technical assistance, maintenance and parts replacement.
When using Duratray dump bodies increases in production can be achieved via reduction in maintenance hours combined with increases in Payload. Moreover wear and maintenance costs compared to steel bodies are notably less, particularly for high abrasion conditions. Fuel consumption is also improved and some cases have demonstrated a 10% in fuel savings.
Duratray products and services are exported from several workshops located worldwide to more than 30 countries across the 5 continents. Some of the mines operating the SDBs globally are located in Australia, Canada, USA, New Caledonia, Chile, UK and recently Kyrgyzstan.
