The Rapid Excavator is a rapid earthworks excavator that
utilizes a cleated track to rapidly and cleanly remove earth
for mining and construction purposes and sees some
application in quarries and landscaping . In it's mobile mode
it looks like a truck sized wedge with
wheels carrying a huge
crawler track. This unit drives itself
to the edge of where an excavation is needed. Here the
wedge stops with the point facing the future hole. Rams
extend from the fat end of the wedge lifting it higher while
pivoting the rear to the ground where spikes hold it firmly
in position. Quickly a dump truck pulls up to the elevated
end of the unit where a short trough projects to
the load center of the truck. The truck will soon be
completely full! Now the track on the back of the
excavator swings up and into action revealing a second
earth moving escalator built into the upper surface of the
wedge. As the whole unit cranks into action the lower and
upper tracks begin to travel. The upper track pivots around
on an articulated guide at the rear of the unit and cuts
cruelly into the earth like a chainsaw with large strong
scoops. Soil and rocks are torn away at the far end and
dragged to the base where they meet the second set of
tracks which carries them up the steep ramp finally
tumbling down into the waiting truck. The Operator looks
down from the small cabin mounted high and to the side
where the controls and gauges at his/her disposal include a
camera to monitor the loading of the truck. With a simple
joystick he can excavate a 20' arc, including pivoting all the
way down to dig a vertical trench. Hydro stats control
angle, pivot, height and rotation allowing for manipulation
and removal of even large rocks. A quick "squat and pivot"
sweeps escaped dirt into the discharge escalator. Instead of
a hydrolic system that would be slammed by every rock and
variation the digger has a forgiving load based
system that regulates the downforce of the excavator
rather than its position preventing it from ever exceeding
the anchoring of the rear of the unit. Jobs begin
from one corner of the excavation and progress in an arc to
the opposite corner. The speed at which this new
can fill full size dump trucks will change the way you bid on
large and time sensitive jobs. Whether inside deep
excavations, digging foundations from the rim, or doing rapid
deep trenching this new rotating excavator has the
eating dust and your dump drivers working twice as hard.
You'll be asking "where can i get faster dump trucks?" and
"why not bid on that time critical big profits highway job?"
and with a steady output of 150 cubic yards of fill per hour
suddenly every mountain starts to look like a big soft mole
hill of future profits.
Circular saw version.

||Ok so the old title was a little to dry.
||Small linked bucket excavators are baked; larger ones suffer from the square-cube relationship.
||They also suffer from the same paragraph break issue as the smaller ones.
||Needs paragraph breaks as fore mentioned. Reminds me of the 1965 October issue of, Excavation Monthly. (Big Red Special edition.)
||[-2fries] - that's definitely the most awesome centerfold I've seen in a while.
