Automated Mechanical Car Park

1. Definition and Functional Positioning

An automated mechanical car park refers to a storage facility that utilises mechanical transmission systems to transport vehicles vertically or horizontally from ground-level entrance/exit points to multi-tier parking bays for consolidated storage, also referred to as mechanical parking equipment. Its primary purpose is to maximise parking capacity within constrained land parcels, slashing the footprint per vehicle to between 1/2 and 1/25 of that required by conventional surface open-air car parks, serving as a critical infrastructure solution to ease city-centre parking congestion. Under the "Catalogue of Special Equipment", automated mechanical car parks are classified as special equipment, subject to stringent statutory safety supervision by market regulatory authorities.

2. Classification and Technical Characteristics

Type	Operating Principle	Applicable Scenarios	Key Features
Lift-and-Traverse Type (Puzzle Parking)	Pallets shift vertically and horizontally to reconfigure vacant slots for vehicle parking and retrieval	Basement car parks in residential estates and commercial office towers	Straightforward construction, cost-effective, commands the highest market share
Vertical Lift Type (Tower Parking)	A high-speed hoist lifts vehicles vertically, with a traversing mechanism moving them horizontally into dedicated parking bays	High-density urban commercial precincts	Footprint <50 m², accommodates 40–50 cars, delivers optimal space utilisation
Shuttle / Flat Moving Type	Independent shuttles on each level travel laterally, interfacing with vertical lifts to complete parking and retrieval	Large-scale public car parks (multi-storey above-ground or semi-basement)	Scalable to thousands of bays; localised breakdowns do not disrupt overall operations
Stacker Crane Type (Aisle Stacker)	Aisle stacker cranes travel along designated lanes, hoisting and conveying vehicles horizontally and vertically to bays	Large-scale public multi-storey parking facilities	Fully enclosed environment, completely automated parking and retrieval
Vertical Rotary Type (Car Carousel)	Pallets circulate continuously in a vertical loop	Compact to medium-sized sites	Occupies just 58 m² to house 34 passenger cars, consuming 35% less power than conventional basement car parks
Simple Lift Type (Two-Post / Pit Car Stacker)	Upper pallet elevates or lowers while the lower vehicle drives straight in	Landed homes, factories, and multi-vehicle private properties	Parks two cars in a single-bay footprint, mechanically simple, relocatable

3. Operating Principle and Control System

Taking the most prevalent two-tier puzzle parking system as an example, the ground-level pallets traverse sideways while the upper-level pallets move up and down. One vacant slot is left open at the ground level; to access an upper-tier vehicle, the ground pallet directly underneath slides across to clear the path, allowing the upper pallet to lower to ground level for the driver to drive in or out. The entire operation is governed by a Programmable Logic Controller (PLC), coordinated seamlessly with automated vehicle recognition systems (number plate recognition + facial recognition), hoisting units, and lateral shuttles. Motorists can initiate operation via access cards, QR code scanning, or mobile apps. In fully automated systems, once the vehicle drives onto the entry bay, an automated transfer unit whisks it away to an allocated bay without requiring the driver to enter the internal structure.

4. Safety Standards and Compliance Requirements

Automated mechanical car parks must strictly adhere to mandatory national safety standards, with updated regulations enforcing tighter safety parameters:

Weight and Dimensional Limits: Systems must be fitted with an overload limiter—triggering an audible alert when vehicle weight hits 95% of rated capacity, and cutting off lifting mechanisms between 100% and 110%; additionally, length, width, and height sensors must be installed to bar oversized vehicles from entry and trigger audio-visual warnings.
Safety Protection Mechanisms: Mandatory fail-safes include anti-drop mechanisms (to prevent pallets from plunging in the event of hoisting failure), emergency stop buttons, pedestrian/vehicle intrusion detection sensors, and integrated wheel stoppers (to prevent rolling on the pallet).
Operational Noise and Response Times: Operating noise must remain under 70 dB, with safety fail-safe response times capped at ≤ 0.2 seconds.
Electrical Safety: Electric motors must feature overcurrent protection circuits and integrated emergency intercoms, alongside robust electromagnetic interference (EMI) shielding for drive controllers.

5. Driver Operational Guidelines

Given the tighter bay clearances, restricted driveway widths, and limited manoeuvring space, parking in mechanical car parks calls for precise driving:

Prior to entry, verify that vehicle dimensions do not exceed the displayed length, width, height, and gross vehicle weight limits.
When reversing into the bay, be mindful of the step-up lip between the driveway and the pallet; apply throttle smoothly to overcome the incline without surging.
Once stationary, firmly engage the handbrake / electronic parking brake (EPB), fold in the side mirrors, and wind up all windows, ensuring the vehicle's bodywork sits squarely within the pallet boundaries.
Upon parking, all occupants must vacate the pallet staging area immediately before the operator or automated system triggers the mechanism. Entering the facility while equipment is in motion is strictly prohibited.

6. Industry Trends and Future Outlook

Mandated Smart Automation Quota: Urban development guidelines mandate that smart automated car parks make up at least 40% of newly constructed public parking facilities, enforcing vehicle recognition accuracy rates of ≥99% and bay allocation times under 10 seconds.
EV Charging Compatibility: 100% of newly designed facilities must incorporate provisions and electrical infrastructure for EV charging points to support electric vehicle adoption; revised fire safety regulations are underway to resolve regulatory and firefighting compliance hurdles for charging points in automated facilities.
Expansion into Heavy Commercial Vehicles: Purpose-built mechanical parking standards for public buses and coaches have taken effect, scaling automated parking solutions from private passenger cars up to public transport fleets.
Cradle-to-Grave Lifecycle Oversight: Stringent routine inspections, scheduled preventive maintenance, statutory safety audits, and certified technician operator requirements continue to elevate overall build quality and operational safety.
