Engineered for high-end aquatic performances and theatrical productions, this concentric multi-ring stage system provides independent vertical lifting and 360-degree rotation for three separate platform levels. The system is specifically designed for submerged or water-feature environments, utilizing a full galvanized anti-corrosion finish and a specialized water-glycol hydraulic medium to ensure environmental safety and mechanical longevity. Controlled via a standard DMX512 protocol, it allows for seamless synchronization with lighting, fountains, and music, creating a dynamic “cake-layered” visual effect. Each unit is precision-engineered to support integrated fountain nozzles and heavy-duty performance loads, delivering professional-grade reliability for modern scenic engineering.

Independent Multi-Ring Actuation: Features three concentric rings (inner, middle, and outer) that can lift and rotate independently, enabling the creation of dynamic “cake-layered” stage configurations and complex performance choreographies.
Submersible Corrosion Protection: The entire mechanical structure undergoes a hot-dip galvanization process followed by a multi-layer epoxy zinc-rich primer and chlorinated polyether topcoat, ensuring long-term durability in underwater or high-humidity environments.
Eco-Friendly Hydraulic System: Utilizes a specialized water-glycol hydraulic medium instead of traditional oil, preventing environmental contamination in aquatic settings while maintaining consistent power transmission.
DMX512 Protocol Integration: Fully compatible with professional theatrical DMX512 control systems, allowing stage movements to be perfectly synchronized with lighting, music, and fountain effects.
Specialized Perforated Decking: The platform surface is engineered with custom-punched perforated plates, specifically designed to allow integrated fountain nozzles to project water through the stage deck from below.
VFD-Regulated Speed Control: Equipped with Variable Frequency Drives (VFD) to provide smooth, adjustable rotation speeds (ranging from 1 to 5 minutes per revolution) and vibration-free vertical travel.
Precision Multi-Level Positioning: Supports accurate and repeatable positioning at three designated heights (low, middle, and high levels) for all three rings, ensuring consistent performance alignment.
Musical Water Shows: Integrated into large-scale aquatic theaters where the stage must operate while submerged, allowing for synchronized motion with choreographed fountains and water curtains.
Theatrical & Opera Houses: Providing a dynamic “cake-layered” platform for performers, allowing for complex vertical level changes and independent ring rotation during live shows.
Night-time Outdoor Entertainment: Serving as the centerpiece for lake-based light shows, where DMX512 control ensures perfect timing between stage movement, laser effects, and background music.
Theme Park Attractions: Used in high-throughput immersive experiences that require robust, high-cycle mechanical platforms capable of operating in demanding wet environments.
Grand Ceremonies & Brand Launches: Offering a sophisticated visual reveal for luxury products or keynote speakers through the independent elevation and counter-rotation of concentric rings.
Multimedia Art Installations: Providing a programmable kinetic platform for kinetic sculptures or digital projection mapping surfaces in modern museum or public square environments.
For this heavy-duty series, we can engineer load capacities up to [300] tons, with platform dimensions and lifting heights customized to your operational envelope. Requirements exceeding our standard engineering matrix will undergo a Finite Element Analysis (FEA) by our engineering team to ensure structural viability before proposing a solution.
To initiate the engineering proposal, please provide the following baseline data:
Rated Load Capacity
Maximum Lifting Height & Closed Height
Platform Dimensions (L x W)
Duty Cycle (e.g., operational cycles per hour/day)
Environmental Conditions (e.g., indoor/outdoor, washdown, explosion-proof)
Pit depth or overhead clearance constraints
Yes. The control systems can be equipped with standard communication protocols (e.g., Profinet, Modbus, Ethernet/IP) utilizing [Siemens / Allen-Bradley / Omron] PLCs. This ensures seamless I/O signal synchronization with upstream/downstream conveyors, AGV/AMR units, and your central control room.
Every custom unit undergoes a mandatory Factory Acceptance Test (FAT) prior to dispatch. This includes continuous operational testing at 100% rated load, static overload testing at [120% / 125%] capacity, and the physical triggering of all mechanical anti-fall and hydraulic safety interlocks. FAT documentation and video proof are included in your engineering package.
Upon final approval of the General Arrangement (GA) drawings, the manufacturing lead time is typically 4 to 8 weeks. Oversized structural components are engineered with a modular design to fit into standard shipping containers (20FT/40HQ). On-site assembly utilizes pre-engineered bolted flange connections and heavy-duty aviation plugs, strictly eliminating the need for field welding.
We provide a standard [12/24]-month warranty covering the structural frame and primary hydraulic/electrical components. To minimize operational downtime, a comprehensive set of standard consumables (e.g., cylinder seal kits, travel switches, relays) is shipped alongside your equipment. During the warranty period, replacement parts for non-human-induced failures are dispatched via priority air freight (DHL/FedEx) within 48 hours.
Beyond the warranty, we guarantee lifetime engineering support. Your custom equipment's CAD drawings, electrical schematics, and BOM (Bill of Materials) are permanently archived in our system. This ensures you receive uninterrupted remote troubleshooting, maintenance guidance, and exact spare parts matching for the entire lifecycle of the equipment.
