BGV C1 REGULATION, Explanation

BGV C1

 is a regulation for Staging and Production Facilities for the 

Entertainment Industry. Lifting and rigging equipment is just part of this 
standard and cover structures and other technical matters.
Adopting 

BGV C1

 is entirely voluntary (except in Germany) but its adoption is 

generally required by insurance companies and therefore it has effectively 
become an industry standard.
The application of this standard over lifting towers is vital due 
to in theatres, stages, etc. are used to move loads over performers 
and, in some cases, above spectators, representing a potential falling risk.

BGV C1 REGULATION, Application fields

This standard is orientated in two ways:
By one side, the lifting towers adopt designs and materials in order to 
achieve a high security degree in magnitudes like load supported, 
balance, friction resistance, etc.
So a

 certified ensures the customer 

that has passed strict test during its design, materials choice or 
load and effort verifications.
By other side, in order to achieve an optimum operation with these 
units, is recommended as much a responsible use of the unit, 
complying basic rules like maximum load accepted or tower balance 
as maintenance periodic, which must be carried by expert technicians, 
checking the good state of the steel cable and winch, operation of 
the safety bolts and folding/unfolding of the entire profile system.
