"The driver doesn't have to raise the hoist as high to get the load to break, and the asphalt flows more easily, quickly and consistently into the paving machine," says John Mundall.
The shape allows Mundall to empty a 26-ton load in the same amount of time that a flat-bottom requires to dump 15 tons. The design also eliminates the need for an apron, which further speeds the process by eliminating the necessary cleaning time.
The lightweight design allows Mundall to carry an extra half ton of payload. "Where it used to take 12 or 15 transfer trailers and six or more 10-wheelers to do 2,000 tons in an eight-hour day, we can do that job with 12 Superdumps in four or five hours," says Mundall. That has led to production increases. "Instead of getting 2,000 tons ready for us, the plants would get 3,000 or 4,000 tons ready."
