Automated fly bar operators control the movements of sets and other elements in a performance based on the artistic or creative concept, in interaction with the performers. Their work is influenced by and influences the results of other operators. Therefore, the operators work closely together with the designers, operators and performers. Automated fly bar operators prepare and supervise the setup, program the equipment and operate automated fly bar systems, rigging systems or systems for horizontal movement. Their work is based on plans, instructions and calculations. The manipulation of heavy loads close to or above performers and audience makes this a high risk occupation.
