Hydraulic Use in the Theatre
In order to impress the viewers, there are some theatrics or theatre crafts that have to be put in place so that the audience can be impressed.
They can make plays or scenes worth watching.
Hydraulic water power is one of the commonly and uniquely used theatrics that has improved over time.
This is practiced all over the world and controlled by someone underneath the stage as the movements are witnessed on the stage.
The upward and downward movement of the theatre stage is also termed as an elevator stage or hydraulic stage. With the use of hydraulic power, some sections of the stage can be lifted and shifted according to the various scenes, thereby improving stage presence.
The bridges within the scene can also be created quietly and invisibly by the use of hydraulic power. The tilting and lifting of the bridges are geared by water power.
High water pressure pipe is fitted to the bottom of the cylinder, and then the high pressure pushes the plungers or the ram upwards to rise and carry the bridge along.
The hydraulic ram carrying a bridge is able to work independently, which makes it useful in raising one bridge end without the other or uplifting to different heights the ends in order to tilt the bridge in either direction when the other appears to be rising instead of tilting. These two different views portray the flexibility of this arrangement.
The portion of lifted plungers, being the amount of the bridges tilted is detected by the portion of water poured to the cylinders. The water portion is controlled through the closing or opening of the taps or valves that regulate the supply.
The bridge valves are operated by long handles, similar to the handles of the signal cabin in a railway. Therefore, they can be easily operated and controlled by an individual or operator through the lifting or tilting of the bridge through holding the handles, one on each hand, and then moving forward and backward as required. Each bridge has two handles. These handles open and close the valves or taps that control water supply. The valves are found directly beneath the platform where the operator stands when operating the handles.
An indicator is then arranged to preview the height portion the bridge ends that have been lifted.
The person operating the handles can see the bridge underside; therefore, the indicator allows him to contemplate on the tilt portion more accurately and with some level of assurance that the position of the bridge during any performance or theatrics arrangement is exactly as required.
Hydraulic stages, therefore, have made it possible for stage scenes to appear more realistic as a theatrics device through the uplifting of the stage, tilting or rocking to simulate motion. On the other hand, these theatre crafts can only be achieved in a large backstage facility, high flying tower, greater width and depth of stages, and increased space understage.
The application of hydraulics in theatre cannot be overlooked, as it has helped the entertainment industry to achieve the desired stage elevation when shooting movie scenes.
