Working with one pick up point this is achieved by pushing
forward the cluster and simultaneously lowers the height of
the system.
Now fix and lock the quick lock pin between the first
speaker of the cluster on the ground and the last of the
hanging cluster.
Continue to lift the cluster and the angles of the speakers
will automatically switch to the correct position.
Stop lifting and insert and lock the second Locking pins
(Safety pins) to prevent the system from going into
compression shifting the tilt of the module, and consequently
of the cluster.
Insert the front locking pins in the proper hole. These are 2
additional pins do not load the weight of the system but
serve to maintain the fixed angle between the modules
especially if they go into compression in very curved systems
Pull out the front and rear pin from the cart and remove it.
Repeat the procedure of the last 4 module for all of the
following modules.
Warning: Although with a single pick up point is possible to
compose a cluster modules 20, it is highly discuraged to use
a single pick up point with more than eight modules. The
hooking and lifting of the last modules would be dangerous
and difficult.
1. SELECT THE
INCLINATION ANGLE
Drop the cluster and remove all locking pins while it is still in traction then place the first cart under it.
Lock the front quick lock pins. Turn up the rear bracket of the module while lifting the cart. Go in the proper position with the
rear part and insert the quick lock pin in the position corresponding to a 1,4 ° hole.
Drop the cluster until the last module of four is fully leaning on each other.
Remove the rear locking pin of the first module of the next series of four and then remove the quick lock pin. Remove the front
quick lock pins, taking great care, because the upper cluster will be free to move.
Pull out the first cluster and repeat the procedure from the beginning.
