摘要： An arrangement for raising and lowering the various movable scenery settings of a theater stage by fluidic control systems. The actuators employed may be utilized as structural tie members providing lateral support for the building beam elements. The control system may be transferred between groups of actuators to economize on installation cost. Furthermore the control system selectively directs pressurized fluid into the actuators when raising or lowering the scenery settings and is provided with a readout system which is indicative of the rate of fluid flow into the actuators.
