Hanger bar system: A row of bars across the stage

A view of the stage from the side. Dozens of steel pipe battens are arranged in parallel across the stage, spaced about twenty centimeters apart. Each is connected by steel cables to counterweights or electric winches on the side. Some battens hold lights, some hold curtains and sets, and some are empty. The steel cables reflect light in the dark. Avoid: depicting only a few battens, having too large a spacing between battens, omitting counterweights and winches, having battens not parallel to the proscenium.

從側台看舞台上空。數十根鋼管吊桿平行排列橫跨舞台,間距約二十公分,各自以鋼索連到側面的配重或電動捲揚機。有的桿掛燈具,有的掛幕與佈景,有的空著。鋼索在暗處反光。避免:把吊桿畫成少數幾根、桿與桿之間的間距過大、拿掉配重與捲揚機、讓吊桿的排列不平行於台口。
