Moxy to build rigid dumptrucks


MOXY Engineering, the Norwegian-based articulated dumptruck (ADT) manufacturers, are planning to add a new dimension to their product range by entering the rigid dumptruck market.

Having acquired the intellectual property of the Aveling-Barford rigid dumptruck range, as well as the rights to use the famous Invicta logo, the company are planning to launch their first rigid truck – the AB51 – in summer 2008.

Developed from Aveling-Barford’s RD44 model, the new AB51 will be powered by a Cummins QSX15 diesel engine producing 447kW at 2,100 rev/min, driving through a six-speed Allison H5600AR transmission with six forward and two reverse gears. With an overall length of 8.30m, a maximum width of 4.25m, a loading height of 3.30m and a wheelbase of 3.93m, the truck will weigh 77.6 tonnes and offer a 46.3-tonne payload capacity.

Made from abrasion-resistant steel and mounted on special supports to absorb shock loads and vibration, the rear tipping body will have a heaped capacity of 28.8m3, while the two-cylinder, two-stage hoist system, fixed to the chassis and powered by a pump directly mounted to the gearbox, will give a tipping time of less than 11s to a maximum angle of 51 degrees.

Power steering with a steering angle of 36 degrees will be by way of two double-acting cylinders and a hydraulic pump geared to the engine. The rear Kessler driving axle will feature inboard planetary reduction gears in both hubs, and oil-immersed brakes will be fitted on the rear axle with dry disc type brakes on the front. Front and rear tyre sizes will be the same with 2100 x 35 tubeless quarry tyres fitted all round.

A major feature of the AB51 will be its new, heavy-duty, sound-proofed cab, which Moxy say, will offer significant improvements over the one fitted to the truck’s RD44 predecessor. Mounted on special supports to reduce vibration, the cab will benefit from a pneumatic suspension seat and air-conditioning as standard, and all engine and component functions will be covered by a comprehensive instrumentation panel.

Commenting on the new dumptruck, Jamie Thomson, Moxy Engineering’s managing director, said: ‘We were delighted with the interest shown by potential customers when the prototype was displayed at the Bauma exhibition in April, despite the fact that production is not expected to begin until mid-2008.’

With quite a long time to production, Mr Thomson admitted that there may be some changes to the specifications in the meantime and added that plans were also in the pipeline to introduce further models in the future.

‘The AB51 will be followed by the AB76 – a significantly updated version of the Aveling-Barford RD65. Also planned is a 100-tonne capacity model, which will be an entirely new design,’ he said.

Although the prototype AB51 was built in the UK, Moxy plan to build the new rigid trucks alongside their ADTs at the company’s manufacturing facility in Elnesvagen, Norway, subject to permission to move the rigids by road to the docks.
