Dynamic DJ performance risers in high-energy nightclubs face severe drink spill risks and mechanical pinch hazards in crowded club layouts. This custom Ø1800 mm circular scissor stage lift features an integrated 360-degree flame-retardant accordion bellows skirt, elevating 1000 kg DJ rigs across a 1000 mm vertical stroke.
Ø1800 mm Circular Deck: Circular geometry optimizes venue sightlines while supporting audio consoles and performers.
Full-Perimeter Bellows Guard: Flame-retardant accordion skirt blocks drink spills, confetti, and mechanical pinch points.
Low-Noise Hydraulic Drive: Remote submerged motor pack limits acoustic interference during live sound sets.

The scissor pantograph mechanism uses laser-cut high-strength structural carbon steel with induction-hardened pivot pins and self-lubricating composite bushings. The round Ø1800 mm platform deck incorporates a reinforced steel sub-frame topped with a durable gloss laminate or anti-skid rubberized surface that isolates turntable vibration. Dual heavy-duty hydraulic cylinders feature hard chrome-plated micro-honed rods and high-integrity polyurethane seals that resist pressure decay under dynamic 1000 kg stage loads.
The electro-hydraulic power pack connects via 5-meter braided flexible hydraulic lines, allowing remote placement inside a sound-isolated backstage cabinet. The modular black PVC accordion bellows skirt unzips via industrial fasteners for lubrication access to cylinder clevis pins. GRADIN provides a 12-month structural and hydraulic warranty, complete electrical schematics, and rapid courier delivery of replacement seal kits.
Operators actuate stage elevation through a compact wireless radio-frequency (RF) handheld remote or a flush-mount wall control console. Proportional descent flow valves provide cushioned acceleration and stop profiles without turntable needle skipping. For venues requiring larger synchronized stage layouts or backstage equipment hoists, venue operators can deploy complementary custom entertainment scissor platforms to expand production staging.
Internal hydraulic velocity fuses close within 0.05 seconds if line rupture occurs, locking the circular deck at current elevation. The 360-degree expanding bellows skirt prevents club patrons and stage crew from reaching scissor nip points during elevation. The stage lift complies with international entertainment and machinery safety directives:
ANSI MH29.1 standard for industrial scissor lifts and movable platforms
OSHA 1910 machine guarding regulations for power transmission apparatus
DIN 56950-1 Entertainment Technology – Machinery Installations – Safety Requirements
CE Machinery Directive 2006/42/EC and Low Voltage Directive 2014/35/EU

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.
