The creation of
Peter De Clerk,
Siemens
, explains
how the company's
PLM software enabled
Lieberr to explore
design alternatives
for its T282 C mining
truck with full vehicle
simulation.
U
ltra-class mining trucks are
big. Average load capacities
run to the hundreds of short t,
an enormous amount
compared to a typical construction-site
hauler that carries 50 short t or less. These
vehicles can travel up to 64 km/h, while
hauling huge loads of coal, metal ores
and other rawmaterials over flat terrain
or up and down the haul roads of the
world’s largest opencast mines, which
can reach depths of more than 600 m.
Companies are particularly drawn to
trucks with electrically-driven wheels
powered by diesel generators instead of
mechanical powertrains with gearboxes
and drive shafts. Diesel-electric trucks are
often easier to operate and they generally
outperformmechanical trucks,
particularly on steep grades. They are
also less expensive and easier to maintain
so that in remote locations, the trucks are
just where they need to be: in the mines
and not in the repair shop.
Biggest of the big
Liebherr’s flagship product is the
T 282 C. With a load capacity of 363 t
