BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a lift stage, and more particularly to a composite lift stage having a wide width that is hydraulically driven.
A lift platform for a stage is a mechanical device generally used in a show and arranged in the stage area to perform a vertical lift movement to realize a special performance effect. It can also be used to transport actors, stage units, and landings. Conventional stage lifting platforms in domestic and overseas theaters generally have a long and narrow shape with a length of about 16 m to 18 m and a width of 3 m to 4 m, corresponding to the width of the theater front stage. The lifting movement of the lifting platform is realized by driving means such as using a steel wire rope, a chain, a gear rack, a screw nut or the like on both sides of the platform body structure. The specific drive means depends on the speed, travel range, configuration conditions, and the like. The lifting platform has a single-layer or dual-layer platform structure that can move up and down while the entire platform is lifted.
Some specific theaters require a longer lifting platform and multiple hoisting substages can be arranged on the lifting platform in a chessboard fashion to meet more complex performance needs. In these elevated platforms, their use will be limited due to the relatively large deformation of the elevated platform caused by the weight of the platform body structure itself as well as its passenger. Thus, traditional delivery routes and driving means can not satisfy application requirements.
In order to solve the above-mentioned problems, the present invention provides a stable composite lift stage having a large overall width with a sub-stage movable relative to each other.
