For example, painted soft and hard flats (e.g., muslin drops) and are commonly used to depict settings. In many stage productions, theatrical scenery is mounted to line sets in order to be flown in and out so as to quickly change set pieces during the course of a performance. Line sets are sometimes dedicated to particular draperies, such as the main (grand) curtain and main border (valance) that mask the proscenium opening, but drapery locations can often vary. borders), legs, cycs, scrims and tabs, as well as associated tracks, in order to mask and frame the stage and provide backdrops. Line sets often suspend theater drapes and stage curtains such as travelers, teasers (a.k.a. When a line set has a predetermined, relatively permanent, function it is known as a dedicated line set. For example, a general purpose line set can usually be quickly transformed into a drapery or scenery line set, but converting a general purpose line set into an electrical line set is more involved. Line sets are typically general purpose in function, meaning they can perform any number of functions which vary depending upon the requirements of a particular theatre production. Theatrical rigging systems are made up of hemp, counterweight and/or automated line sets able to serve various functions.

Together, a series of parallel line sets regularly spaced up and down stage, commonly at 6 in (150 mm), 8 in (200 mm), or 9 in (230 mm) centers, comprise the bulk of most fly systems. Otherwise it relies solely on the motor power of an electric hoist to fly a line set.

hand line or purchase line) allows riggers on the fly crew to raise and lower the batten.Īutomated rigging sometimes uses weights to help balance line set loads in a manner similar to manual counterweight rigging. The lift lines are reeved through a series of pulleys, known as blocks, that are mounted above the stage to fly loft structure. In manual rigging, a line set’s lift lines support weights opposite their connections to the batten in order to balance the weight of the batten and whatever it carries. A batten is suspended from above by at least two lift lines, but long battens may require six or more lift lines. Battens may be just a few feet in length or may extend from one wing (side) of the stage to the other. A batten is said to be 'flying in' when it is being lowered toward the stage, and 'flying out' when it is being raised into the fly space. By hanging scenery, lighting, or other equipment on a batten, they in turn may also be flown. The function of a typical line set is to fly (raise and lower) a slender beam (typically a steel pipe) known as a batten (or a bar in the UK) by hoisting it with lift lines (typically synthetic rope or steel cable). The line set is the fundamental machine of a typical fly system. 5.4 Counterweight system loading procedure.2.2.1 Double-purchase counterweight system.Theatrical rigging standards are developed and maintained by organizations such as USITT and ESTA (now PLASA). Building, occupational safety, and fire codes limit the types and quantity of rigging permitted in a theatre based on stage configuration.

Theatrical rigging is most prevalent in proscenium theatres with stage houses designed specifically to handle the significant dead and live loads associated with fly systems. Systems are typically designed to fly components between clear view of the audience and out of view, into the large opening, known as the fly loft, above the stage.įly systems are often used in conjunction with other theatre systems, such as scenery wagons, stage lifts and stage turntables, to physically manipulate the mise en scène.

Fly loft of the Theater Bielefeld in GermanyĪ fly system, or theatrical rigging system, is a system of rope lines, blocks ( pulleys), counterweights and related devices within a theater that enables a stage crew to fly (hoist) quickly, quietly and safely components such as curtains, lights, scenery, stage effects and, sometimes, people.
