1. Safety | Intended use
The MCT24 main-cradle-frame was developed for use in professional sound systems. The
main-cradle-frame may only be used by trained and qualified personnel.
The MCT24 main-cradle-frame may only used with the T24(N) loudspeaker.
This rigging manual describes how to use the MCT24 main-cradle-frame correctly. Any other
use shall be deemed improper and may result in damage or even injury.
Modifications or alterations to individual parts of the MCT24 main-cradle-frame are not per-
mitted! Danger to life!
WARNING
Before every operation, check the scope of delivery of the MCT24 main-cradle-frame for its
completeness and ensure that all parts are in perfect condition.
The scope of delivery includes specified components. Only use the recommended and cer-
tified components.
WARNING
The MCT24 main-cradle-frame is designed both for indoor and outdoor use.
CAUTION
The MCT24 main-cradle-frame may only be used by trained and qualified personnel.
Personnel must check the MCT24 main-cradle-frame for suitability before each use.
WARNING
The MCT24 main-cradle-frame must be taken out of operation immediately as soon as visible
damage to the parts can be seen.
WARNING
Please keep all elements of the MCT24 main-cradle-frame away from children! The small
parts can easily be swallowed and lead to suffocation!
WARNING

ThepayloadoftheMCT24 main-cradle-frameisdesigned ofnotmorethan 12x T24(N) loudspe-
aker. The following additional components are required for this: CBT24 cradle bar for flying,
BAT24 adapter, BBT24 bracket and BLT24 Boxlink connecting cables on both sides of the
T24(N) loudspeaker. Do not exceed this payload.
WARNING
When moving (assembling, dismantling, maintaining) the MCT24 main-cradle-frame with
T24(N) loudspeaker, ensure sufficient space to prevent collisions with other objects.
WARNING
Do not squeeze or twist the electrical cables of the T24(N) loudspeaker during the installation
of the MCT24 main-cradle-frame! The respective national electrotechnical rules and regula-
tions are applicable.
CAUTION
Before mounting the MCT24 main-cradle-frame check that e.g. ceilings are capable to
carrying the payload of the components.
WARNING
WARNING
WARNING
Make sure that no water pipes, electrical lines or any other lines are behind the intended place
of mounting.
Only use wall plugs and screws which are suitable for the intended mounting and structural
fabric. All screws must be set and tightened properly. Ensure that the fixing holes have the
correct depth and diameter. Always use all fixing holes.
Check the Double Stud connections each time you install the MCT24 main-cradle-frame.
They must be firmly engaged and secured with a safety locking splint. If this is no longer pos-
sible, the Double Stud connections with the safety locking splints must be replaced.
When working with heavy loads exceeding 20 kg (44 lbs.), use suitable aids (dollies, hoisting
slings, etc.). Multiple persons may be required depending on the situation.

4.2 Wind load
WARNING
WARNING
TW AUDiO recommends using only the accessories specified by TWAUDiO for securing and
mounting loudspeakers.
Before setting up the system outdoors, consider unexpected wind conditions at the opera-
tion site!
Disassemble your system immediately when wind speeds exceed 8 bft (34 to 40 kn / 62 to
74 kph / 38.5 to 46 mph) and secure the system components!
Make sure that there are no persons in the immediate vicinity of the system structure!
Make sure that the system structures are not operated over the audience at wind speeds in
excess of 6 bft (22 to 27kn / 39 to 49kph / 24.2 to 30.45mph) and that there are no persons
in the immediate vicinity of the system structure!
Please note that setting up the MCT24 main-cradle-frame always requires two persons!

4.7 Mounting of two MCT24 main-cradle-frame
WARNING
Screw the two MCT24 main-cradle-frames to the side beams as shown for example in
figure 4.7. For this purpose, use the hexagon screws and nuts included in the scope of deli-
very.
For applications where the T24(N) system cluster needs to be extended laterally, two
MCT24 main-cradle-frames can be bolted together at the side beams.
Before screwing the two MCT24 main-cradle-frames together, always note the pin points
that match your application. Also note that your system setup is held in the horizontal position
with the ASK44 sling chain!
Determine always the pin points you require before setting up the system!
Only then screw the two MCT24 main-cradle-frames together!
