Stacking and Flying with Easy-rig™

The

S

asy-rig™ flying system has been designed to set up acoustic vertical line-arrays in an easy,

fast and flexible way. All the necessary cabinet rigging hardware is stored within the SP20-Linex
housing. In general, the only additional requirements include an

S

asy-rig™ fly-frame and tilt-

bar, motor hoists, transport flight cases and qualified rigging personnel.

6.1

Safety Guidelines

The workload limits (WLL) as specified in this manual of SOUND PROJECTS rigging accessories
have been designed with a safety factor 10. This is well above the European guidelines for lifting
machinery. Other safety guidelines are given throughout this paper.

It‘s the users responsibility that all safety precautions have been taken when using
flying hardware equipment.
