Moxy start MT51 production
Moxy Engineering raised the stakes in articulated dumptruck manufacture last April when they unveiled the MT51, currently the world’s largest ADT, at the Bauma exhibition in Munich. As one of the world’s leading manufacturers of ADTs, Moxy say the MT51 typifies the company’s determination to enhance its reputation as a front-runner in the design and development of the concept.
As this issue of QM went to press, the first MT51 production models to be built at the company’s Elnesvagen facility, near Molde, in Norway, were expected to start rolling off the production line following two years of design, development and testing of the first prototypes.
Jamie Thomson, Moxy’s managing director, said: ‘As one of the originators of articulated dumptrucks, Moxy have brought the concept to a new level. The design team has really excelled itself with the MT51, everything has been improved from running costs to driver comfort.’
The MT51 offers a 46.3-tonne payload capacity together with level and heaped body capacities of 22.8m3 and 28.8m3 respectively. It is powered by a Tier III-compliant Cummins QSX15 water-cooled six-cylinder diesel engine with an output of 374kW, driving through an Allison 4600 ORS six-speed automatic transmission with lock-up in all gears.
Like the other models in the range the new model has permanent six-wheel drive, a free-swinging rear tandem bogie, articulated hinge system, independent front-wheel suspension and a sloping rear frame, while the dual-circuit hydraulically operated brakes have enclosed oil-cooled multiple wet discs all round.
The MT51 flagship joins the four other established Moxy models – the MT26, MT31, MT36 and MT41 – now offering payloads from 23 tonnes to just over 46 tonnes, with engine outputs ranging from 228kW for the MT26 up to 374kW for MT51.
To complement and extend this five-product ADT line-up, in August Moxy Engineering announced a new development with the acquisition of the intellectual property of the Aveling-Barford rigid dumptruck range and the rights to use the famous Invicta logo.
Developed from Aveling-Barford’s RD44 model, the new AB51 is 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. The truck has an all-up weight of 77.6 tonnes and offers a 46.3-tonne payload capacity. A two-cylinder, two-stage hoist system, powered by a pump directly mounted to the gearbox, gives a tipping time of less than 11s to a maximum angle of 51°.
A major feature of the AB51 is its new heavy-duty, sound-proofed cab, which is said to be a great improvement over that of its RD44 predecessor. Mounted on special supports to reduce vibration, it has a pneumatic suspension seat and air-conditioning as standard.
Production of the AB51 is not expected to begin until mid-2008 but plans are already in the pipeline to introduce further models in the future, including the AB76, a significantly updated version of the Aveling-Barford RD65, and then a 100-tonne capacity model, which will be an entirely new design.
Although the prototype AB51 was built in the UK, Moxy are hoping to build the rigid trucks alongside the ADTs at their manufacturing facility in Elnesvagen, subject to gaining permission from the Norwegian authorities to move the trucks by road to the docks.
