Rigger (event technology)
Riggers are height workers in event technology who are busy assembling and dismantling the trusses at events. The riggers hang the traverses with chains, ropes, lifting loops and shackles at certain points under the hall ceiling.
The trusses usually consist of aluminum profiles in the form of trusses. Special electric chain hoists or manual chain hoists are used to raise and lower the elements, some of which weigh tons . In the theater, prospect trains are preferably used.
An acceptance by the structural engineer etc. usually only takes place in the case of very complex constructions .
In the case of temporary structures according to DIN 4112, the responsible building authority checks the statics and creates a test book from it. The erection of a temporary structure must be reported in writing to the competent authority at the construction site two weeks before the start of construction. As a rule, the competent authority sends an inspector to accept the building with the aid of the inspection book. In this z. B. Drawings, conditions, static calculation, arrangement and position of the ballast, permissible trailer loads, wind force limitation, material certificates, etc. are available.
With normal structures up to two points, a load calculation can be carried out without any problems using the manufacturer's load tables. From the third point on, these calculations were so difficult that they had to be carried out by a structural engineer.
The term rigger originally referred to the people who are involved in the rigging of sailing ships.
education
The IGVW (Interest Group for the Event Industry) defines three levels of training to become experts in event rigging.
The event trigger "Level 1" carries out simple rigging activities that pose a low risk. The type of activity is determined by the training, knowledge and experience of the person.
The creation of temporary attachment points is only permitted under the supervision of an event trigger with at least "Level 2" evidence. Level 2 is necessary for performing all rigging activities independently. The activities of the event trigger "Level 2" correspond to the expert for event rigging according to SR 3.0 (VPLT standards for event technology - expert for event rigging). He bears the technical responsibility for his area of responsibility, with the exception of: Working with an increased degree of risk or with non-standardized constructions. These are only carried out by a "Level 3" event trigger.
The event trigger "Level 3" has special technical qualifications and leadership qualities, which are required in the event of a high degree of risk to the services or non-standardized constructions. He is responsible for the planning, management and supervision of the rigging trade .
The so-called "rigger license" in the industry is acquired upon completion of the courses "Level 1" to "Level 3", the certificate of competence for event rigging SQQ2.
