Duratray International is a specialist
designer and manufacturer of high-efficiency Dump Bodies for mining and quarry haul
trucks.
The principal product-line offered is the unique Duratray rubber Suspended Dump Body
(SDB). This design consists of a thick but flexible rubber wear mat supported on high-capacity
synthetic suspension ropes which are anchored and tensioned into the sides of a high-tensile skeleton
steel frame; the entire load-carrying system has been upgraded over years of development and has evolved
to become a truly low-maintenance dump body compared to traditional trays lined with abrasion resistant
steel.
The Duratray SDB provides benefits in terms of resistance to extreme abrasion,
reduced maintenance requirements - hence higher operational availability, significantly reduced
carry-back with wet or cohesive materials, lower shock and vibration to the truck and its operator, plus
reduced noise levels during loading and discharge. In addition Duratray SDB dump bodies
are lighter in weight and have higher volumetric capacities than standard steel dump body designs from
haul truck manufacturers.
Duratray dump bodies are currently operating globally on mine & quarry haul trucks
from 30 tonnes to 380 tonnes capacity and are enjoying increased levels of acceptance in large-scale
mines for minerals such as copper, nickel, coal, bauxite, gold, diamonds and iron ore. Duratray
dump bodies are operating successfully on ultra-class haul trucks such as the Caterpillar-797B
and Komatsu 930E-4 models with more than fifty units in this size range.

Duratray equipment is durable and works in a variety of applications.
Duratray SDB's are located from the far north of Norway (70ON in a quartzite mine),
across to the Arctic Circle in Canada (at the Ekati and Diavik diamond mines), down through the taconite
iron ore mines of northern USA, the copper mines of Arizona and Mexico, to the bauxite mines of Jamaica,
Guyana and Suriname.
Throughout the Chilean copper industry Duratrays are successfully operating in all
of the large open pit mines such as:
- Chuquicamata
- El Abra
- Escondida
- Collahuasi, and Los Bronces
In the Australasian region there are Duratrays in PNG, Indonesia and New Caledonia,
