Two Post Parking Lift — Hydraulic Self-Locking Automated Parking System
The PJS two post parking lift is the most deployed automated parking system globally — simple in concept, reliable in operation, and accessible in cost. Two vertical columns raise and lower platforms independently, parking two vehicles in the space of one. The hydraulic cylinder with self-locking check valve provides fail-safe platform retention without electronic dependency. Rated for 2,300-3,200kg per vehicle, with platform lengths up to 5,300mm accommodating most passenger vehicles including SUVs and full-size trucks. The 220V single-phase power requirement means no dedicated electrical infrastructure — standard commercial power is sufficient. Installation completes in 48-72 hours on a prepared concrete slab.
For residential, small commercial, and any site requiring 2-6 parking spaces with minimum complexity, the two post lift is the engineering-first choice.
Features — Why Choose a Two Post Parking Lift
1. Hydraulic Self-Locking Safety
Check valve technology provides mechanical self-locking — the platform holds position without any power consumption. This is fundamentally different from motor-driven systems that require electronic braking. When the hydraulic pump stops, fluid flow is blocked by the check valve, and the cylinder cannot extend or retract. This makes hydraulic self-locking the most fail-safe approach for safety-critical parking applications.
Every PJS unit also includes a mechanical anti-fall device that operates independently of the hydraulic system. Combined with overload sensors (triggering at 110% rated capacity) and photoelectric barriers at entry/exit, the system meets CE safety requirements for unattended operation.
2. 220V Single-Phase Power
The PJS two post lift operates on standard 220V single-phase power — the same as a household electric range or air conditioner. This eliminates the most common barrier to automated parking installation: electrical infrastructure upgrades. No 380V three-phase service, no dedicated transformer, no utility coordination. Most existing commercial and residential buildings have sufficient electrical capacity for 1-4 units without any upgrade work.
Power consumption during operation: 2.2-3.0 kW. Standby power: negligible. Operating cost per cycle: approximately $0.15-0.30 in electricity.
3. Rapid Installation — 48 to 72 Hours
Equipment installation completes in 2-3 days from start to operational testing. The PJS arrives pre-assembled in modular sections — the hydraulic power unit comes pre-run from the factory, minimizing on-site welding and fitting. Site requirement: a flat, level concrete slab (minimum C25 grade, 200mm thickness). No pit, no special civil works, no drainage.
Typical timeline: site preparation 1-2 weeks → equipment delivery → 48-72 hour installation → operational testing → handover.
4. Compact Footprint — 6m × 3m per Unit
Each PJS two post unit occupies a 6m × 3m = 18m2 footprint and parks 2 vehicles. Compared to surface parking at 30-36 m2 per vehicle (including drive aisle proportion), the two post lift delivers 2x land efficiency. Clear layout dimensions of 6m length enable basement and rooftop deployment in standard residential and commercial building footprints.
5. Hydraulic Cylinder Drive — Simple and Maintainable
The PJS uses a single or dual hydraulic cylinder per column, mechanically simple and proven in millions of installations worldwide. The check valve provides inherent self-locking — no electronic brake system required for the primary safety function. Chain and sprocket reduction drives the platform through a 1:50 ratio, providing smooth, controlled movement at 60-90 seconds per full lift cycle.
Maintenance intervals are predictable: annual fluid check, 3-5 year fluid replacement, hose inspection every 2-3 years. The failure mode is slow — hydraulic leakage is visible and audible before catastrophic failure, allowing planned maintenance rather than emergency repair.
6. Residential and Commercial Compatible
The PJS two post lift serves applications from single-unit residential installations to 12+ unit commercial arrays. The 220V compatibility makes it the only automated parking system that can be installed in existing residential buildings without electrical infrastructure changes. For commercial applications with higher cycle requirements, the 380V configuration provides additional power for more frequent operation.
