Introduction to Symmetry Vertical Platform Lifts
Symmetry Vertical Platform Lifts (VPLs) are designed to provide safe and reliable wheelchair access in both residential and commercial buildings. These lifts are ideal for overcoming barriers posed by stairs while maintaining aesthetic appeal and structural integrity.
Available Models:
- VPL-UL: Unenclosed Lift: A cost-effective, open-design platform lift ideal for indoor or outdoor applications with minimal travel height requirements (up to 60 inches). Best suited for areas where an enclosed hoistway isn’t necessary, providing quick and easy accessibility without compromising safety.
- VPL-EL: Enclosure Lift: Fully or partially enclosed with durable steel construction, this model is designed for both indoor and outdoor applications. It provides enhanced protection against environmental elements and ensures user safety with an enclosed shaft.
- VPL-ELP: Plexiglass Enclosure Lift: Similar to the VPL-EL but with plexiglass panels for enhanced aesthetics and visibility. This model combines safety and style, making it an excellent choice for public and commercial spaces where design is a priority.
- VPL-SL: Shaftway Lift: Designed to be installed within a pre-built hoistway or shaft. This model integrates seamlessly into buildings with dedicated elevator shafts, offering a clean, built-in look for multi-level access.
- VPL-Hybrid: Hybrid Lift: Combining features of both enclosure and shaftway lifts, the Hybrid model offers flexibility and customization for unique installation requirements. It is ideal for retrofitting existing buildings or addressing non-standard accessibility challenges.
Each model serves unique applications, ranging from simple unenclosed solutions for minimal height travel to fully enclosed lifts capable of operating in outdoor environments with extreme weather conditions.
Structural Requirements and Installation Considerations
Floor and Wall Support:
- Stationary Load Capacity: Floors must support a load of 3,200 lbs.
- Wall Support Requirements: Walls must withstand a pull-out force per bracket bolt as indicated on the provided plans.
- Reinforced Slab for Outdoor Installations: Outdoor lifts require a 4-inch reinforced concrete slab rated for 3,200 psi, complete with adequate drainage.
Pit Requirements:
- Standard Pit Depth: 3 inches is recommended for optimal performance.
- Low-Profile Pit Option: A 1.5-inch pit depth is available for installations requiring minimal excavation. This option can also reduce ramp length for applications without pits, offering greater flexibility in tight spaces.
- Outdoor pits must include proper drainage systems to prevent water accumulation.
Hoistway Preparation:
- Must be plumb, level, and square.
- Ensure proper overhead clearance in compliance with local building codes.
- Lintels above doors and gates must be capable of supporting additional load.
Tip: Always consult the Symmetry VPL Design Guide for precise structural requirements and diagrams.
Electrical System Overview
A robust electrical system is essential for smooth operation and compliance with NFPA 70 (NEC 620, USA):
- Power Supply: Dedicated 120VAC, 20A, 60Hz circuit with a fused disconnect.
- Lighting Requirements: Maintain at least 100 lux lighting at platforms and landings.
- Pit Requirements: Include a GFCI outlet and switch.
- Emergency Backup Systems: Optional full-speed battery backups are available for uninterrupted performance.
Pro Tip: Work with a licensed electrician to ensure compliance with local and national electrical codes.
Entrance and Exit Configurations
Gate and Door Specifications:
- Gate Height: Minimum 42 inches above the top landing.
- Gate/Platform Alignment: Ensure doors and gates align seamlessly with the platform.
- Automatic Gate Operators: Required in 90-degree access configurations or when using ramps instead of pits.
Ramp Options:
- Stationary Ramps: Ideal where pit installation isn’t feasible.
- Flip-Up Ramps: Common in unenclosed applications, requiring safety pans and interlocks.
- Low-Profile Ramps: Available when paired with the 1.5-inch low-profile pit option, reducing required ramp length.
Entry/Exit Options:
- Straight-Through Access: Simplest and most common configuration.
- 90° Access: Suitable for tight spaces or corner installations.
- Same-Side Access: Limited to specific models.
Outdoor Installation Considerations
Outdoor environments demand additional preparation:
- Foundation: Install on a 4-inch reinforced concrete slab with proper drainage.
- Weatherproofing: Use plexiglass inserts or weather-resistant enclosure materials.
- Ventilation: Fully enclosed units should include ventilation systems to prevent moisture buildup.
Extreme Weather Package:
For coastal regions or areas exposed to harsh weather, the Extreme Weather Package ensures durability and longevity.
- Powder-Coat Finish: Protects against rust and corrosion.
- Materials: Exposed components are made from 304 stainless steel, galvannealed steel, hot-dip galvanized steel, and aluminum.
This package significantly extends the lift's lifespan in challenging conditions, making it an ideal solution for coastal installations.
Compliance and Safety Standards
All Symmetry Vertical Platform Lifts comply with:
- ASME A18.1 – Safety Standards for Platform Lifts.
- ICC A117.1 – Accessible and Usable Buildings and Facilities.
- NFPA 70 (NEC 620) – Electrical Code Compliance.
- ADA Guidelines – For commercial and public spaces.
Engage local code officials early to confirm compliance and secure necessary permits.
Common Use Cases for Symmetry VPLs
- Residential Homes: Improving multi-level accessibility.
- Public Spaces: Schools, offices, libraries, and places of worship.
- Commercial Buildings: Restaurants, retail stores, and small businesses.
These lifts are adaptable, reliable, and aesthetically versatile, making them suitable for both interior and exterior applications.
