DESIGN THE SYSTEM
The HDL6 Shape Designer software is divided into two macro sections: the left part of the interface is dedicated to
project variables and data (size of audiences to cover, height, number of modules, etc.), the right part shows the
processing results.
At first the user should introduce the audience data choosing the proper pop-up menu depending on the size of the
audience and introducing the geometrical data. It is also possible to define the height of the listener.
The second step is the array definition selecting the number of cabinets in the array, the hanging height, the number of
hanging points and the kind of available flybars. When selecting two hanging points consider those points positioned at
the flybar extremes.
The height of the array should be considered referred to the bottom side of the flybar, as shown in the picture below.
HEIGHT
After entering all the data input in the left part of the user interface, by pressing the AUTOSPLAY button the software will
perform:
- Hanging point for the shackle with A or B position indicated if a single pickup point is selected, rear and front load if
two pickup points are selected.
- Flybar tilt angle and cabinet splays (angles that we have to set to each cabinet before lifting operations).
- Inclination that each cabinet will take (in case of one pick up point) or will have to take if we were to tilt the cluster
with the use of two engines. (two pick up points).
- Total load and Safety Factor calculation: if the selected setup doesn't give Safety Factor > 1.5 the text message shows
in red color the failure to meet the minimum conditions of mechanical safety.
