Vertical Circulating Mechanical Parking System
A type of mechanical parking equipment that adopts a vertical circulation mechanism to move parking spaces in
vertical circulating motion to the access level for vehicle storage and retrieval.
Note: This definition is excerpted from GB/T 26476-2011 Terminology for Mechanical Parking Equipment
The motor drives the large and small sprockets via a reducer, which further drives the main shaftadopting the assembled U-groove plate driving
technology, and then actuates the heavy lifting chains.
Vehide pallets are mounted on the heary chains at fixed interals The pallets perform vertical dirculating motion perpendicular to the ground.
Smooth vehicle parking and retrieval are realized through sequential cyces of stop – circulation – stop

Its core technology enables safe and uninterrupted charging of the garage whether it is running or stationary.
05.Special Intelligent Fire Extinguishing System for Stereo Garage
The system is independently installed on each vehicle-carrying tray and controlled intelligently by temperature sensors with passive self-activation. Nano dry powder extinguishing agent is directionally ejected from nozzles under high pressure of inert gas, which realizes timely fire suppression at the initial stage of vehicle combustion and minimizes losses to vehicles and the garage.It solves the drawbacks of traditional supporting fire protection systems in stereo parking garage construction, such as complex structure, difficult construction and high investment cost.

03. Intelligent Instant Braking Technology for Chain Breakage
This technology adopts the working principle of direct-acting hydraulic discbraking. During normal operation of the parking equipment, the extra-largebrake disc (nearly 1200 mm in diameter) rotates synchronously with the driveshaft, while the brake pistons and friction pads remain open and inactive. In case the small drive chain breaks under extreme working conditions, the device activates instantly and completes braking of the main drive spindle within 0.5 seconds to prevent the circulating chain from falling out of control,thus safeguarding both the equipment and vehicles.

Premium Safety Device Options
High-Density Residential (Old Apartments & Condos)
- The Problem: Older residential properties were never built with the grid capacity or physical space for EV chargers, causing landlords to lose eco-conscious tenants.
- The Solution: A rapid-deployment rotary carousel installed on the property perimeter solves the tenant parking crisis while providing overnight slow-charging that won’t overwhelm the old building’s electrical transformer.
The Hybrid Model: Rotary AC + Ground DC Hubs
- The Problem: Commercial charging sites waste prime ground space on cars that have finished charging but haven’t been moved by the owner.
- The Solution: Ground-level bays are exclusively reserved for JiuRoad
Ultra-Fast DC Integrated Machinesfor rapid 15-minute turnover transit. Alternatively, long-term parkers are elevated into the AC Rotary System. This dual-layer strategy perfectly captures both high-speed transit revenue and long-duration parking revenue simultaneously.
Rotary Kinematics Meets High-Voltage Engineering
Delivering continuous electrical power to 16 heavily loaded, constantly rotating vehicle platforms presents an immense engineering challenge. JiuRoad’s proprietary technology ensures safe, unbreakable power flow.
Dynamic Rotary Power Transmission
Continuous Slip-Ring Power Matrix: Eliminates the danger of tangled cables. We utilize industrial-grade conductive slip-rings and brush systems on the central rotational axis, allowing uninterrupted AC power flow to each pallet, even while the massive carousel is in motion. Intelligent AC Load Balancing Technology: The master controller dynamically throttles the AC output across the rotating vehicles , ensuring optimal charge completion times without tripping local breakers.
Heavy-Duty Rotary Mechanical Moats
Anti-Sway Pallet Stabilization Technology: Precision-engineered pendulum linkages ensure the vehicle platform remains completely parallel to the ground during multi-axis rotation, preventing any vehicle shift or mechanical stress. Heavy-Duty Steel Chain Drive Mechanism: Forged, oversized drive chains capable of managing the immense torque required to rotate 16 fully-loaded electric (heavy battery) vehicles effortlessly. Low-Vibration Silent Motor Drives: Acoustically optimized mechanical drives allow the 12-meter tall structure to operate legally within noise-restricted residential zones.
Automated Operational Safety
Multi-Point Photoelectric Detection System: A mesh network of optical sensors scans the entrance bay before rotation. If a human, pet, or open car door breaches the safety perimeter, the mechanical brake triggers instantaneously. Rotary-Integrated Fire Suppression: Individualized aerosol or gas fire suppressors are mounted to each moving pallet, creating an isolated safety envelope around every charging vehicle. Emergency Manual Retrieval Override: In the event of a catastrophic city grid failure, the system's mechanical release allows gravity or secondary backup motors to safely cycle vehicles down to the ground.
One-Touch Retrieval & Unified Cloud Billing
- 90-Second Rapid Retrieval: Drivers do not wait. By swiping their RFID card or tapping their App, the intelligent
Bidirectional Shortest-Path Algorithmcalculates the quickest rotational direction (clockwise vs. counter-clockwise) to deliver the vehicle to the ground level in under 90 seconds. - Plug, Lock, and Leave: The driver parks on the ground pallet, plugs in the AC cable, exits the bay, and confirms on the touchscreen. The system autonomously lifts the car out of sight.
- Aggregated Digital Billing: The backend CSMS seamlessly merges the data. When the user retrieves the car, the system processes a unified digital payment combining the spatial rental and the energy use

FAQ
Why does the rotary system use AC chargers instead of DC fast chargers?
Rotary systems are inherently designed for “long-dwell” parking (e.g., offices, hotels, residential), where vehicles sit for many hours. AC destination charging () is perfectly suited for these timeframes. Additionally, DC power modules and heavy liquid-cooled cables are too bulky and heavy to safely integrate into the moving pallets of a rotary structure.
How does the power cable not tangle when the entire structure is rotating like a Ferris wheel?
We use advanced continuous electrical slip-rings (similar to how power is transferred to a rotating wind turbine blade) embedded in the central axis infrastructure. This transfers continuous electrical current to rigid conductive pathways on the moving pallets, entirely eliminating external cable tangling.
What substrate or foundation is required to install this system?
Because of the concentrated downward weight of 16 EVs and the steel carousel, a specialized reinforced concrete foundation is required. However, the exact civil engineering footprint is remarkably small—roughly the size of two standard parking spaces ().
Is the Automatic Rotary System customizable?
Yes. We offer comprehensive OEM/ODM exterior cladding. The steel frame can be enclosed in architectural façade panels, glass, or LED advertising screens to seamlessly blend into urban environments or generate secondary out-of-home (OOH) media revenue.
