A unique ‘V’ profile floor, designed to actively channel the load to the centre of the tray, is one of the standout design features of Austin Engineering’s new Ultima dump truck body.
Designed and manufactured by the Australia-based engineer, the new body also features improved structural integrity and payload advantages, the company said.
Based on Austin’s WESTECH, JEC and JEC-LD series of bodies, the new tray is lighter and stronger than current original equipment manufacturer (OEM) bodies, which translates to a 10-15% weight saving without sacrificing payload, according to the company.
This is the next generation in mining dump bodies, Austin Engineering says, with the Ultima carrying a greater payload, meeting all OEM dump truck specifications and delivering the industry’s lowest cost per tonne.
“By channelling the payload to centre line of the tray, the unique V-floor, with its lower centre of gravity, improves machine stability and safety and reduces overall tray wear,” the company said. “The floor design also reduces dump cycle times (empty is achieved at 3/4 tipping).”
The body also features large radius transitions to assist in the reduction of material carry-back, which also provide superior impact resistance and substantially extend operating life, Austin said.
“Overall the optimIsed shape of the Ultima body means better material distribution within the structure while maintaining the payload/weight advantage,” Austin Engineering said.
The new body’s increased structural integrity gives superior impact and wear resistance, extends fatigue life and lowers maintenance costs, according to the company. Tapered sides run the full length of the body to minimise wear, assist in carry-back reduction and reduce side spillage in the dumping cycle, while a low-profile rear floor shape, combined with a reduced height bolster, provide additional ground clearance when dumping.
The body is available in both ‘Straight Floor’ or ‘Flow Control Combo’ designs to cater for fixed or varying SG values and is designed to operate as a liner-less configuration.
“It can be adapted to suit any mine specific application, is suitable for any current OEM dump truck chassis and is designed to comply with all OEM haul truck operating limitations,” the company concluded.
