MEILLER Typ D321 three-way tipper
Three-way tipper for three-axle chassis up to 33 t, nominal load capacity 21 t, with a body length of 4.4 to 5.1 m.
MEILLER Typ D321 is a three-way tipper from the TRIGENIUS range, for three-axle chassis with a technically permissible gross weight of up to 33 tonnes. The body unloads on three sides – left, right and rearward – with a single telescopic cylinder in front of the body, so the same vehicle works on a cramped construction site and on an open landfill.
Compared to the D316, this is a class up: the same body geometry and the same materials, but a nominal load capacity of 21 tonnes on a heavier chassis. It is chosen when stone, rubble and concrete debris are hauled daily and when load capacity, not volume, determines how many trips the vehicle makes.
