CargoMaster
bda_c141_d_06_07

Congratulations, you acquired a powerful and versatile machine to
transport loads.
The CargoMaster will shortly be an indispensable help to you.
However, in order to transport heavy loads effortlessly up- and
downstairs, it is necessary to acquire a certain skill in using the
CargoMaster.
For this reason we ask you to read the operator´s manual carefully
and pay particular attention to all warning and safety instruction
before using the CargoMaster for the first time.
We further suggest that, in order to get used to this stairclimbing
device, you practise handling it first without loads. Please practise
at the lowest speed possible.
For safety reasons it is mandatory to observe strictly the maximum
limit for loads.
For damage done by exceeding the maximum load or improper use
such as...
•warped axles
•deformed frame
•deformed handles
we do not assume any warranty.

CargoMaster

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 sha-
king 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.
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 "Funcional 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 motor´s axle in such a
way that the lever (B2) rotates around the motor´s axle (D3) and
the lever (B1) in an opposite direction around the connecting axle
(D2). The axle (D1), connected to the climbers, thus makes the up
and down movement necessary for the CargoMaster´s climbing
process. The climbers, guided on the rail (E), follow that move-
ment.
Depending on how levers (B1 and B2) climbers (C) and frame are
located in relation to each other there are certain positions in
which the CargoMaster should preferably be driven or parked.
How the up and down movement of the CargoMaster´s climbers
and frame can be used to climb stairs is desribed and explained as
you read on.

CargoMaster

For the description of the functional sequence we assume that the
CargoMaster´s climbing mechanism and the climbers are at their
highest position as shown in Fig. 3.
This is the position in which one drives the CargoMaster on level
ground. It is further the position in which one can rest the Cargo-
Master on its toe plate. In the following description of the functio-
nal sequence this neutral or starting position of the CargoMaster is
called position 0°.
The First Phase
Drive the CargoMaster to the first step of the stairs in position 0°.
Push the UP/DOWN switch "UP" and the motor begins to rotate.
Both levers of the climbing system rotate as well and the climbers
move downward.
The climbers touch the ground and
take over the load. The motor conti-
nues to rotate, and because the rota-
ting movement is transfered to the
climbers, the frame is pushed up-
ward, i.e. lifted.
The motor lever´s rotation moves from
90° to 120° and you notice that the big wheels pass over the edge
to the next step. At approximately 180° the climbing mechanism
lifts the frame to the next step, and the big wheels take over the
load once more (see Fig. 4). This concludes the first phase.
The Second Phase
Once the big wheels take over the load on the next step
at approximately 180°, the climbers are lifted as well
passing 210° and 270°.
At 330° the climbers are "retracted" sufficiently so that
the CargoMaster can be pulled back to the edge of the
following step (see Fig. 5). The final position, 360°,
coincides with the starting position 0°, which conclu-
des the second phase. Now you can repeat the process.

CargoMaster

Before you use the CargoMaster for the first time, please make
sure the batteries are completely charged, as shown in chapter 8.2
"Charging the Lead batteries".
F
Retract the climbers entirely by pushing the UP/DOWN
switch.
Unlock the safety brakes with the tip of your foot. You
need to push the stopping levers upward until the looking
mechanism opens. Now the brake levers move down un-
encumbered, and the braking wheels touch the ground as
shown in Fig. 7.
Then, tilt the machine towards you until the frame´s
loading surface is almost in a horizontal position. At
this point the safety brakes must engage and lock the
running wheels. If the machine cannot be pushed for-
ward, but only rolled backward, then the braking effect
for a safe use of the CargoMaster is achieved.

For the safe operation of the CargoMaster, it is imperative to ob-
serve all requests for caution and all instructions of the operator´s
manual as well as all safety measures and instruction labels on the
machine itself.
FThe CargoMaster may only be used by a trained person.
FDuring operation, never put your hand underneath the toe
plate.
FCheck the safety brakes each time you use the machine.
FTo climb up- or downstairs always unlock the safety brakes.
FThe maximum load, see label on the machine, may never
be exceeded.
FEach load you transport must be secured with the safety
belt.
FAvoid using the device in wet conditions. Do not operate
the CargoMaster in the rain or in a carwash, etc.. Make
sure that the load, e.g. a washing machine, does not leak
water that could get into contact with the device because
this could lead to malfunction or damage of the
CargoMaster.
FIf any of the power-driven elements of the CargoMaster
lock, turn off the machine immediately.
FNever transport people with the CargoMaster.
FOnly operate the CargoMaster in conjunction with the
safety devices that belong to the particular machine.
FPlease turn off the CargoMaster, i.e. put the power switch
in postition "0", when you stop the machine or take a break
in transporting a load.
FRepair work on the CargoMaster may only be done by the
manufacturer or authorized dealers.
FOnly use original spare parts by AAT Alber Antriebstechnik
GmbH.
FPeople under age are not allowed to operate the
CargoMaster (except those over 16 who are trained under
supervision).
FMake sure that the batteries are recharged after each
operation.

You will manage the climbing process without problems and in
next to no time, if you follow instructions closely. At first you
should practise climbing stairs up an down with the CargoMaster
without loads to get familiar with the device and how it works.
1To climb stairs, drive with the CargoMaster backwards to-
ward the stairs and then you climb 2 to 3 steps. Please make sure
that the CargoMaster´s big wheels are touching the edge of the
lowest step and the climbers are in their utmost position (see Fig.
15).
F
FCargoMaster
2Push the UP/DOWN-switch "UP" to initiate the climbing pro-
cess. The motor rotates while the climbers lift the frame plus load.
F
3The climbing process takes place in two phases per step. The
first phase is finished when the running wheels touch down on the
next step and take over the load from the climbers.
F
14
CargoMaster

4The second phase starts with "retracting" the climbers before
the lifting process begins.
It ends when the climbing mechanism has reached the next step
and is in its neutral position.
Because the CargoMaster is always pulled slightly backward, it
rolls automatically to the next step (see Fig. 20). The climbing
process repeats itself as described in 5.2..
15
CargoMaster

F
1Push the CargoMaster, climbers in utmost position, all the
way to the edge of the stairs. The unlocked safety brakes make it
impossible that the CargoMaster goes over the edge of the stairs.
2Push the UP/DOWN-switch “DOWN” and the CargoMaster
begins its descent. The downward movement starts with the lowe-
ring of the climbers to the next step.
3As soon as the climbers touch the surface of the next step,
the frame begins to move downward until the big wheels also
touch the step. Now push the device again to the curb of the follo-
wing step and repeat the process described in point 2.

CargoMaster

The CargoMaster model C 141 is equipped with a foldable toe
plate thus storage and transportation of the device is comfortable
and easy because it does not take up much space. If the automatic
lock of the toe plate loosens, you should tighten the screw that
holds the toe plate. Please do that on both sides (there are always
2 screws SW 13 on each side).
In a regular position the toe plate is lo-
cked by a bolt (1).
If you flip the lever (2a) from a vertical to
a horizontal position (2b), the bolt (2c)
moves upward, unlocking the toe plate
(2d).
The thus unlocked toe plate can be
folded up by 90° (3a).
In this position you can fix the toe
plate by flipping the lever (4a) in a
horizontal position so that the bolt
(4b) lowers itself into the aperture
at the toe plate and locks it (4c).
18
CargoMaster

Due to the handles adjustable in height and angle the
device can be adapted ideally to any situation of trans-
portation. The storage dimensions of the device itself are
considerably smaller than those of the standard model.
F
If you unscrew the locking screws approximately 6 mm the
plates of the clamps can be pulled apart so that a locking-
bolt clears. At that point the handle that is in a vertical po-
sition can be moved forward or backward.
Adjust the handles in such a way that the locking bolt is in-
serted in one of the three drilled holes in the clamp.

The portable stairs are especially developed
for the CargoMaster to overcome obstacles
higher than 50 cm (~20") such as e.g.
ramps, platforms or loading areas of trucks
(see Fig. 24)..
