Jon Pope - Super Dozer 500

Nothing says Americana as much as supersized vehicles – and the Super Dozer is a machine with a blade that measures 35.17ft wide by 15.35ft tall.

The rest of the machine structure is 61.8ft long, 25.78ft wide and 26.1ft tall.

The Super Dozer is modular and can be broken down into 10 components that can be transported from jobsite to jobsite.

Its main use would be in the mining sector, but as it can be taken apart and
reassembled without the use of a torch, it could be used in very
large, long-term infrastructure projects such as new superhighways.
It can also be transported to new mine sites instead of being scrapped
on-site due to its extreme size.

The Super Dozer is powered by two 3,000hp diesel electric power
plants, providing 6,000hp in total. Although the machine might look
as if it steers by articulating, it is actually a skid-steer, so the centre
oscillates instead of articulating.

The machine is made up of two chassis, with the centre oscillation point enabling them to twist independently of each other. This gives better ground contract, which translates into better traction, flotation, lower ground pressure
and a smoother ride.

The cab is on a bridge in the middle of the machine, and can shift
from one side of the dozer to the other. This gives the operator a
better view of the edge of the blade on either side of the machine.
The cab can be rotated 45° and 90° to reduce stress on the operator
when performing a series of back and forth manoeuvres. Because the
blade is so large, when it is raised high it becomes almost impossible
to see forward, so the cab can rotate a complete 180°, enabling the
machine to travel backwards without the blade obstructing the
operator’s view.
