Haulmax Releases 90m³ Body for Extended Haulage of Lightweight Materials
23 November 2009
Haulmax has released a large capacity rear dump body for its 3900 Series, designed for hauling light materials.
At a capacity of 90m³ (118 cubic yard), the body incorporates a scissor tailgate assembly to ensure material retention over extended haulage distances. The new size complements the standard 50m³ (65.4 cubic yard) and 38.5m³ (50.3 cubic yard) rear dump bodies.
The ribless body design offers strength and robustness without forsaking weight. Manufactured from 400-450 grade abrasive resistant steel, it is ideal for low specific gravity materials such as coal, lignite, limestone, flyash and potash.
The first large capacity body unit is currently en route to South Africa. After a trial period it will be taken into use in the hope of generating a significant population growth in the coal mining industry there and other regions of the world.
With the market expanding for this unique haulage product, Haulmax have recognised a niche which they describe as The Haulmax Solution™, combining extended haulage distance with a narrow profile, flexibility and reliability. The aim is to build a purpose-designed 'off-highway' hauler, incorporating safety enhancements such as enclosed wet disc brakes on the dual rear wheel drive axles and roll over protection structure (ROPS) as a standard.
A braking system built for harsh conditions
The braking system, which is inherent to typical 'off-highway' haulers, offers inbuilt reliability, fade resistance and exceptional retarding capabilities; enhancements unique to the enclosed wet disc design. Haulmax chose this concept based on their experience of alternative braking methods being more susceptible to reliability issues under the harsh conditions found on mining sites.
In the larger capacity Haulmax trailer version, the 3900-T, the trailer axles incorporate the same brake groups as found on the drive axles of the cab chassis unit.
In a recent product trial in New Zealand, inclement weather conditions occasionally prevented the operation of traditional haulers. The Haulmax, however, continued to operate safely due to its surefootedness from its traction and braking capability in soft and slippery underfoot road conditions.
The flexibility of the Haulmax product also allows it to be safely used as a tow tractor, service unit and water wagon.
Operation and maintenance features
Accessibility of maintenance, safety of mechanics and ease of service rate highly as KPIs for Haulmax. Walk-around inspections are enhanced with an easy-to-read transmission sight glass and radiator coolant level sight glass, along with highly accessible system filters. Access steps and platforms complete with handrails are standard fitments to under-hood service areas.
Operators are well catered for with easily traversable stairways and an air-conditioned and sound-suppressed ROPS/FOPS cabin offering excellent visibility from an air ride seat incorporating a three point safety harness. The same standard is offered for the operator trainer or passenger.
A Cat® power train and systems offer high availability and reliability via the world recognised aftermarket support of the global Caterpillar dealer network.
