Stage Load Specications
An air transporter is designed to receive acoustic towers varying in size from
4877 to 9754 mm (16' to 32') high, 3048 to 3658 mm (10' to 12') wide, 1448 mm (4' 9") deep and weighing
up to 885 kg (1950 lb).
The machine is only intended to lift and transport Wenger Diva Acoustic Towers.
Floor Level Specications
An air transporter must only be used on level ground.
Required Working Environment
An air transporter is designed for use indoors in a normal working environment.
The intended operating temperature range is 7°C (45°F) to 35°C (95°F). It must only be used on level ground,
on a smooth solid oor with no ridges, holes or obstructions.
Main Electrical Power Supply
A power switch is provided to enable an air transporter
to be disconnected from the main electrical supply.
When the power switch is switched from the
OFF position to the ON position, the earth
connection is made before power connections
are made. When the power switch is switched
from the ON position to the OFF position, power
connections are broken before the earth connection
is broken. In the OFF position, the electrical power
supply is removed from the entire machine.
The electrical power supply is provided by
the use of a standard power cord.
The standard power cord must be routed
where there is no risk of personnel tripping and
falling because it has been routed in areas where
personnel are expected to walk. It is recommended
that cables should be routed away from such areas,
run in rubber ramps or the area cordoned o󰀨 to
keep people away.
Ground Connection
The blower motor, electrical control box, and metalwork of the machine are bonded to earth (ground) to prevent
a build up of static electricity. This is necessary to ensure that there is no risk of an increase in the voltage
potential of the blower motor, electrical control box and metalwork of the machine as a result of static electricity
that might be generated.
The earth conductor in the incoming main power supply is connected to a protective earth terminal and one
cable taken from this terminal to an earth distribution connector block. Functional earth connections to the
blower motor, electrical control box, and metalwork of the machine, etc. are connected to the earth distribution
connector block.

Operation
Ambient Light Levels
An air transporter is only intended for use inside buildings where there will be articial lighting.
Ambient lighting must be su󰀩cient for operators to see inside and around all parts of the machine.
There is no need to provide additional internal lighting under the hood. Maintenance personnel can see
all internal parts when access covers have been removed and there is no need to provide additional internal
lighting.
Local ambient lighting should achieve a light intensity of 300 LUX around the air transporter and in
the immediate vicinity of those parts of the machine where maintenance must be performed.
There are no exposed rotating parts on an air transporter that might put operators at risk if there are
stroboscopic e󰀨ects due to lighting powered by a 50 or 60 Hz AC mains electrical supply.
This is because all rotating parts of an air transporter are behind plain metal panels or hoods.
Control Devices
The control device for raising and lowering the front caster is a foot activated mechanism. This is located
at the rear center of the base. Operators stand behind the handlebar of the machine where they are able to
see all parts of the machine while it is being maneuvered. A second person is needed to determine whether
there are other personnel who might be in the path of the machine. This makes it possible for operators to
safely maneuver acoustic towers.
The power switch is hand operated and located at the upper rear of the base shroud. In this position it is
easy to access and operate. There is no need for adjustment, the power switch is accessible to persons of
all heights. The power switch is a positive action on/o󰀨 switch that has immediate feedback of being engaged
or disengaged. The device only provides lift and does not provide locomotion. One person can lift all heavy
items that need to be lifted for maintenance with ease. The machine does not determine the work rate because
the operator is not required to position acoustic towers onto the machine at a rate that is set by the machine.
Control devices are located at levels where tall and short operators have ease of access and where they are
in full view of the operator. The function of each control device and what it achieves is marked alongside each
control using characters that are typically 6 mm or more high. There is only one set of controls and no risk of a
second operator being able to control the machine using a second set of controls in conict with the rst.

Operation (continued)
Tower Set Up
In normal operation, an air transporter can be maneuvered manually with ease once the air cushion
has been inated. There is little risk of fatigue by the operator. The force needed to push the assembly is
13.6 kg (30 lb) and this is not excessive. Acoustic towers weigh up to 885 kg (1950 lb) and are positioned
manually, with minimal physical e󰀨ort.
While maneuvering the machine, two people are required. One person is needed to push the air transporter
while the second person is needed to ensure that the way is clear for an acoustic tower to be moved forward.
To assist operators, the acoustic towers are positioned simply by engaging lugs on the air transporter in the feet
of an acoustic tower. This enables tall and short operators to position the acoustic towers without the need to
reach or stoop and is not stressful.
Provided acoustic towers of the correct type are presented to the machine, there should be no handling
problems. Operating instructions provide instruction on how to attach acoustic towers to an air transporter and
how to check the security of acoustic towers so that they cannot come loose.
1. To move the air transporter when it is not supporting an acoustical tower, tilt the front end upward on the
rear casters about 10 to 15 degrees. The front caster will drop downward and lock into place.
Move the air transporter to the acoustic tower that is to be moved.
To move the air transporter when not
supporting a Tower, tilt the front end
upward about 10 to 15 degrees
Never use the air transporter for
any purpose other than to move
and position towers.
Never attempt to manually lift or
move a tower without using an
air transporter.
!CAUTION !CAUTION
Never move a tower on an
inclined surface or ramp.

2. Press inward in the caster release plate with the toe of
your shoe to disengage the caster lock and allow the
front of the air transporter to lower to the oor surface.
3. Position the air transporter under the tower with
the lifting hooks under the lifting brackets on both
sides of the tower.
Be sure that the extension cord is long enough
to reach wherever the air transporter will be
moved.
Prevent cord interference or damage by having
another person manage the cord while moving
the towers.

Tower Set Up (continued)
7. With one person pushing the tower and a second person guiding, slowly move (no faster than 0.3 m [1 foot]
per second) the tower to the performance position.
Be careful to not push the tower into any obstructions on the stage oor or above the stage oor
(such as ceiling panels, etc.).
Note: It is best to create permanent marks for the nal
performance locations for all towers before moving
the them from storage.
8. When the tower is in the nal performance location,
turn o󰀨 the air blower by turning o󰀨 the power switch.
Note: As the air escapes from the air pads, the tower
will tilt slightly forward.
9. Remove the Diva Air Transporter from the acoustic tower
as follows.
a. When the air pads are deated, pull the air transporter
away from the acoustical tower until the lift hooks are
clear of the tower lift brackets.
b. Place a foot against the rear of the air transporter and
tilt the front upward until the front caster locks into place
(down position).
c. Move the air transporter to the next acoustical tower to
be moved.
10. Repeat these steps to move the remaining towers to their
performance positions.
Never move a tower faster than 0.3 m (1 foot) per
second. Moving an acoustic tower carelessly or
too fast can cause an accident such as tipping it
over or running into objects.
!CAUTION
Operation (continued)
Two or more people must work together when
moving a tower. One person must watch for
obstructions on the stage and above the stage
while a second person pushes the tower.
!CAUTION
A dangerous pinch point develops
when lowering a tower to the oor.
!CAUTION
Pull the air transporter clear of the
acoustic tower and tip front end
upward to deploy the front caster
(lock into the down position).

11
Power Failure
If there is a failure of the main electrical power supply, the air transporter ceases to operate.
When the main electrical power supply has been restored, power is returned to the air transporter and the air
cushions will inate. The air transporter only provides lift, and does not provide locomotion. There is therefore,
no risk of a air transporter moving unexpectedly following failure of the main electrical power supply.
Abnormal Uses
Examples of abnormal uses to which an air transporter should not be put. Wenger takes no responsibility for
the safety of machines if they are used for any purpose other than the intended purpose as specied in these
instructions.
● Crushing, impact or entrapment should an acoustic tower topple because an air transporter is used to
transport shells or other panels besides those prescribed.
● Crushing, impact, or entrapment as a result of failing to connect acoustic towers to the machine using a
suitable means of attachment.
● Crushing, impact or entrapment should an air transporter be used to lift and transport a heavy load other
than an acoustic tower and the machine fails structurally.
● Exposure to any hazards on the machine as a result of operating the machine under the inuence of drugs
or alcohol or while wearing loose clothing.
● Exposure to ying or ejected objects caused by using poor quality replacement parts that have been
obtained from an unauthorized source.
Operation (continued)
Never use the air transporter for
any purpose other than to move
and position towers.
When using the air transporter be
sure that all electrical connections
will not separate and interrupt power.
