Counterweight Fly System Diagram

Raue center for the arts mike vandercook and lindsay wolf take us behind the scenes of the theater s fly tower to show us how the rigging system works.

Counterweight fly system diagram.

But rope systems are often included as an auxiliary system. When a near balanced condition occurs the effort required to fly a set in or out equals the amount of system friction plus the inertia to move the load. All users must be. The technology that makes spectacular performance effects happen in theaters and performing arts centers is available in standard designs and formats for smaller spaces and many churches have chosen.

Normally the arms are held inside the flywheel by hefty springs but if the lift moves too fast they fly outward pushing a lever mechanism that trips one or more braking systems. Most elevators have an entirely separate speed regulating system called a governor which is a heavy flywheel with massive mechanical arms built inside it. Rigging wall that allows the counterweight arbors to travel lower than the stage floor to provide in creased batten travel. Today the main fly system is rarely a rope system.

Well equipped theatres often have a flyrail on both stage left and right. Each empty pipe batten has weight and therefore counterweights must be added to the arbor for that batten. Double purchase meaning the weight of the counterweights on the arbor equals twice the weight of the scenery batten. Designed to allow the fly rail where you control the system to be on a raised level.

Designed system of permanently installed hoists and a control system is easy to use and is a lower risk approach than a counterweight system. Also the room or space be low that slot. A counterweight system is meant to be operated in a near balanced condition. The house back of house boh backstage noun the area of a theatre not open to the public.
