Controlling the Biggest Water Show on Earth

摘要

When heavy loads and precise motion control with pinpoint repeatability are needed, electrohydraulics is a frequent choice - even when operations occur under water. Taking in Franco Dragone's "The House of Dancing Water" production in Macau, China's City of Dreams, is breathtaking. Sophisticated staging is actually composed of eight different lift sections. The stage sits atop a forest of hydraulic cylinders that lift and lower the sections up to 27 ft. in the world's largest indoor swimming pool. At times the lifts are raised to form a dry stage and at other times, they independently recede to produce a water pool for swimmers, only to emerge again carrying large props such as a pagoda structure and a 26-ton ship.
