Abstract:		 Modifications being made to the Barbican Theatre, a Grade-II-listed building, will include removal of a set of large, custom-built lighting windlasses that formed an important part of the theatre's original stage machinery. The windlasses were designed to meet the needs of the Royal Shakespeare Company, for whom it was convenient to set up all of a season's plays at the outset, storing unused scenery and lighting in the upper area of the extra-tall fly tower. The windlasses allowed lighting bars to be arranged differently from season to season and raised and lowered during the course of a season. Prior to their removal, an analytical record was made of the windlasses. It is understood that one windlass is to remain in position, and also that the counterweight chains of all the windlasses are to be left in place. The 10 hand-operated windlasses on the 100-ft-high grid each comprised a set of reels solidly fixed to a horizontal axle. As a windlass's axle turned, lines would either be reeled in or out depending on which way they had been wound onto the reels. Wound in one direction on any windlass's largest reel was a set of electrical cables and a wire rope leading to a suspended box of lighting power points. Wound in the opposite direction on the second largest reel of the windlass was a wire rope to lift an increasing amount of heavy chain, as a counterweight. Power for the lights was supplied through solid connections from fixed sources on the grid to the moving cables by means of a third, drum-like reel on the windlass axle. Each windlass was supported on a pair of steel rails in an arrangement that allowed socket boxes to be dropped almost anywhere within the fly loft. The small cable head pulley of each windlass could be moved to change the position from which a socket box was suspended. Also, at least theoretically, the windlasses could be moved upstage or downstage along their steel rails, although this would have been a very difficult operation.
