Why load monitoring on stage is so important

Why load monitoring on stage is so important

Tons of equipment above people : Hanging tons of sound , lighting and video equipment above spectators and performers is a serious matter , especially in light of the trend of ever increasing load weight and movement .
Statically Indeterminate Structure Phenomenon : Each time there are more than two hoists on a truss or more than three hoists in a structure , it becomes statically indeterminate , resulting in an unpredictable load distribution . In most cases this will cause a load imbalance , in which some of the hoists may reach overload while others carry only a small part of the load .
The leveled truss illusion : The belief that leveling a structure will automatically
www . EilonEngineering . com create an even load distribution is a dangerous misconception ; no connection exists whatsoever between a leveled structure and one with an even load distribution . Because of the unpredictable load distribution , overload situations might happen to the most experienced riggers .
Weather conditions :
This phenomenon may be exacerbated by weather effects such as strong winds or snow build-up on a roof . These conditions might reduce the overload tolerance of the structure which carries the rig .
The solution : In order to ensure safe shows , real-time load monitoring and overload detection is a must - from installation and throughout the entire show until dismantle .
