Counterweight Fly System Diagram

Well equipped theatres often have a flyrail on both stage left and right.

Designed system of permanently installed hoists and a control system is easy to use and is a lower risk approach than a counterweight system. Any additional objects flown from the batten will require that additional weights be placed on the arbor. Rope systems are often used for temporary or custom rigging as rope systems are easier to adapt than counterweight or winch systems. Auditorium noun the seating area or audience chamber of a performance space.

The house back of house boh backstage noun the area of a theatre not open to the public. But rope systems are often included as an auxiliary system. Refer to figure 4 5 for a diagram that shows the components of a counterweight fly system. Most elevators have an entirely separate speed regulating system called a governor which is a heavy flywheel with massive mechanical arms built inside it.

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. A counterweight system is meant to be operated in a near balanced condition. Also the room or space be low that slot. 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. Streamlined to allow more line sets in a theater since counterweights don t take up as much space as sand bags. 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. 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.

Each empty pipe batten has weight and therefore counterweights must be added to the arbor for that batten. All users must be. Double purchase meaning the weight of the counterweights on the arbor equals twice the weight of the scenery batten.
