Brief Survey
3.1
General Information
Everybody who sees the CargoMaster in action for the first
time is fascinated by its climbing mechanism.
Precisely those people who are technically inclined end up
shaking their heads as they try to understand how it
works.If one did not see the
CargoMaster actually climb up-
and downstairs, one would reach the conclusion that this
couldn’t possibly work, and yet it does.
3.2
The Functional Principle
The major focus lies at the axle (D3) of the
CargoMaster’s
power unit (A) around which the levers (B1 und B2) rotate
(please see also 3.3 “Functional Sequence”).
The big wheels and the braking wheels are not powered, but
rotate freely on their own axles.
A chain and tooth wheel system integrated in motor lever
(B2) and lifting lever (B1) transfer the rotation of the mo-
tor’s axle in such a way that the lever (B2) rotates around
the motor’s axle (D3) and the lever (B1) in an opposite di-
rection around the connecting axle (D2). The axle (D1), con-
nected to the climbers, thus makes the up and down
movement necessary for the
CargoMaster’s climbing pro-
cess. The climbers, guided on the rail (E), follow that move-
ment.
Depending on how levers (B1 and B2) climbers (C) and fra-
me are located in relation to each other there are certain
positions in which the
CargoMaster should preferably be dri-
ven or parked.
How the up and down movement of the
CargoMaster‘s climb-
ers and frame can be used to climb stairs is desribed and
explained as you read on.
