Abstract (en)

[origin: EP2617918A2] A combined elevatable stage comprises a main platform, sub-platforms and a main control system. The main platform includes a base structure (1), main platform fixing and guiding devices (2), and main platform actuating devices (3). The base structure is a steel structure. The main platform fixing and guiding devices are positioned at both ends of the base structure. The main platform actuating devices include hydraulic cylinders disposed symmetrically and hydraulic driving means. Elevatable sub-platforms are attached to the surface of the main platform which can make vertical and relative movement with relevance to the main platform, or individual movement when the main platform moves vertically as a whole. All the sub-platforms can be actuated to move individually, synchronistically or in groups, to create more motion effects and better meet performance needs, while the elevating distance of the whole elevatable stage is also extended.
