꿈의 도시 수중 무대 리프트 시스템 | 세계 최대 상업용 수영장 플랫폼 | '춤추는 물의 집'의 핵심 기술

프로젝트 개요

As the engineering core of Macau’s “The House of Dancing Water”, this submersible lift system enables dynamic stage transitions in the world’s largest commercial pool (Ø48.8m×7.9m depth, 3.7M-gallon capacity).

With 8 main and 3 auxiliary lifts driven by 6 hydraulic power units, it transforms a 26ft-deep pool into a dry stage in <60s, creating 3D performance space for aerial acrobatics, 25m-high diving, and aquatic choreography

도전 과제

Deep Submersion Operation: Lifts must withstand ≥0.8MPa hydrostatic pressure at 7.9m depth while maintaining sealing integrity；
Heavy-Load Precision Control: Achieving ±1mm synchronization under 146-ton dynamic load to prevent stage tilt；
Ultra-Fast Transition: Completing 2,000㎡ pool-to-stage conversion in ≤60s demands extreme hydraulic response；
Performance-Safety Criticality: Zero mechanical failure tolerance with 300+ performers (including 25m-high divers)

솔루션

Hybrid Hydraulic Topology: 6 power units drive zones independently; Dual-acting cylinders for main lifts + single-acting for auxiliary precision positioning；
Closed-Loop Synchronization: PLC-based feedback with proportional valve pressure modulation ensures ≤1mm sync error across 8 lifts；
Deep-Sea Sealing: Multi-layer bellows seals + anti-corrosion alloy coating withstand 3-5ppm chlorinated water；
Triple Safety Redundancy: Mechanical end-stops + hydraulic overload protection + real-time load sensors trigger emergency stop
