DAC 120 DE
Encyclopedia
The DAC 120 DE was a large earth-hauling dump truck
designed by DAC
, a Romanian
manufacturer of heavy equipment, truck
s and buses and produced by Mecanica Mârşa (near Avrig
).
Designed in 1988, following the American Lectra Haul dump truck model, it became one of the largest earth-hauling truck
s in the world. The DAC 120 DE had an empty weight
of 90 tonne
s, and a maximum capacity
of 120 tonnes. It was 10 meters long and 5.4 meters tall over the canopy, with a wheelbase of 3.2 meters. The model was driven by a 8-ton, 65 litre diesel engine
, capable of producing 1,040 horsepower
(768 kW
). This engine powered two Electroputere
Craiova
electric traction motors in the rear axle. The top speed
of the truck was 70 km/h empty and 55 km/h when completely full. The truck had two 1,600 litres fuel tank
s capable of moving the DAC 120 DE (when full) on a 24 hours schedule an entire week.
The total number of trucks built was around 15, of which eight went to the Roşia Poieni copper mine
, three at the Mahmudia
lime quarry
, two at the Danube-Black Sea Canal
site and five at the Mc Caimy Monster Pilbara iron ore mine
in Western Australia
.
The cost of a DAC 120 DE truck was around US$ 300,000, five times cheaper than other models produced in the 1980s.
