Pit Lifts

The mechanized pit lift is another method of adjusting the floor level of the open pit area. A pit lift has a much higher initial cost, but its lower operating cost and greater flexibility make it the preferred method. It consists of a guided, steel-framed lift table supported by lifting columns within a partially open hoistway. In a simple arrangement, the lift table has stops matching the covered pit level (for use as an orchestra pit), the auditorium floor level (for additional seating), and the stage level (for an extended apron).

The lift table can be set at any intermediate elevation, so it can be used to adjust the floor level of the orchestra pit—for example, to create a shallow pit for Baroque opera. Of course, this creates an elevation change between the open and closed portions of the pit and limits accessibility for musicians using wheelchairs.

If more than one lift is provided, the lift tables can be adjusted individually to alter the size of the orchestra pit or apron extension. Or the lifts can be used to create a stepped floor within a larger pit. Many variations are possible. If the project can only afford one lift, the lift can be sized for the smaller pit and a platform system used for the larger pit, on the assumption the larger pit will be used less frequently. A flexible arrangement with multiple pit sizes and a single lift is also possible, as shown in Figure 10.3 and discussed further below.
