A vertical platform lift, commonly referred to as a wheelchair lift, is a mechanised device engineered to elevate wheelchairs and their occupants between different levels. This equipment serves as a practical substitute for traditional home elevators, with several distinctive features.
Unlike conventional residential elevators, vertical platform lifts often feature an open design rather than a fully enclosed cabin, which simplifies installation in various environments. These lifts employ different drive mechanisms that are typically more compact, making them ideal for shorter vertical travel. Consequently, they usually require minimal modifications to the installation site, offering a more convenient and less invasive option for users.
Wheelchair lifts are especially advantageous for individuals who do not have the space to accommodate a full-sized residential elevator. They are perfect for low-rise applications, such as transitioning from a ground floor to an elevated porch or deck. Additionally, these lifts can be designed for outdoor use, providing a robust and reliable solution for accessing multiple levels outside the home.
How do wheelchair lifts work?
The core mechanism of a wheelchair lift involves either a hydraulic system or an electric motor. Hydraulic wheelchair lifts use fluid pressure to move the platform. When the lift is activated, hydraulic fluid is pumped into a cylinder, pushing a piston that raises the platform. This type of lift is known for its smooth and quiet operation, and it is capable of lifting heavier loads. On the other hand, electric wheelchair lifts are powered by electric motors that drive a screw or a chain to raise and lower the platform. These lifts are generally easier to install and maintain compared to hydraulic lifts.
Safety features are a crucial component of wheelchair lifts. Most lifts are equipped with safety sensors that detect obstacles and stop the lift to prevent accidents. Additionally, they often include barriers or gates that secure the wheelchair on the platform during transit, ensuring that the user does not accidentally roll off. Emergency stop buttons and backup power systems are also standard features, providing peace of mind in case of power outages or mechanical failures.
The operation of a wheelchair lift is straightforward, typically involving a user-friendly control panel. Users can control the lift using buttons or a joystick, allowing them to easily raise or lower the platform to the desired level. In public settings, lifts often come with key switches or remote controls to prevent unauthorised use. Regular maintenance is essential to ensure the long-term reliability and safety of the lift, which includes routine inspections, lubrication of moving parts, and testing of safety features.
Key Components of Wheelchair Lifts
Even though wheelchair lifts take up less space than residential elevators, they still comprise several vital parts:
- Battery Backup: Ensures the lift can be safely lowered during a power outage. This feature is crucial for providing uninterrupted service and peace of mind to users, especially in areas prone to power interruptions.
- Drive Mechanism: The mechanical or hydraulic system used to raise and lower the lift platform. This component is the heart of the lift, determining its efficiency and smoothness of operation.
- Electric Drive: Converts electricity into mechanical motion, powering both hydraulic and screw drive lifts using either AC or DC current. This part ensures that the lift has the necessary power to function effectively.
- Enclosure: Walls that enclose the lift. Not all lifts have enclosures, but all must use sidewalls and gates to protect the rider. Enclosures provide additional safety and security, particularly in multi-level homes.
- Ramp: Provides access to the platform when a pit is unavailable. Ramps can be folding or stationary, depending on the lift type. The ramp design affects the ease with which a wheelchair user can enter and exit the lift.
- Grab Rail: A handle for the user to grip for added safety. This simple yet essential feature helps prevent accidents and provides additional stability for the user.
- Lift Control Buttons: Requires constant pressure to operate, offering more control over the lift. This design allows the user to stop the lift immediately if necessary, enhancing safety and convenience.
- Lift Platform: A non-skid surface that allows the wheelchair to grip easily. It can be made from rubber, metal strips, or textured paints. A well-designed platform ensures safe and easy entry and exit for the wheelchair user.
- Safety Sensor: Detects obstructions and halts the lift to prevent accidents. This feature is crucial for ensuring the lift does not cause harm to people or pets that might accidentally be in the way.
Types of Wheelchair Lifts
There are several models of residential vertical platform lifts to consider:
- Residential Wheelchair Lifts: These simple, one-floor lifts raise the user to the next level and are usually installed next to stairs. They are ideal for homes where installing a full elevator is impractical.
- Unenclosed Wheelchair Lifts: Ideal for porch lifts, landscape elevation changes, and mobile home decks. They are generally used for single-floor elevations and are perfect for outdoor applications where enclosures might not be necessary.
- Enclosed Vertical Platform Lifts: Completely enclosed for added security, these lifts require slightly more space. They are a popular choice in private residences for their safety and weather protection.
- Shaftway Lifts: Enclosed lifts typically hidden behind doors for a discreet appearance. These lifts blend seamlessly into the home’s architecture, making them an aesthetically pleasing option.
- Enclosed Plexi-glass Lifts: Stylish lifts with plexi-glass infill enclosure wall panels. These lifts offer a modern look while providing the safety of an enclosed lift.
- Hybrid Wheelchair Lifts: These look like home elevators but use the same constant pressure operating system as platform lifts. They offer a full-height car and a range of optional features and finishes, making them a luxurious yet practical choice.
When selecting a wheelchair lift for home use, there are several important factors to consider. First, evaluate the space requirements to determine how much floor space the lift will occupy. This is especially critical in smaller homes where space is limited. Next, assess the installation process. Some lifts require significant modifications to the home, while others can be installed with minimal changes.
Understanding the warranty is also crucial. Be sure to know what the warranty covers and its duration, as a good warranty can save you money and hassle in the long run. Additionally, identify any extra features that might be beneficial. Features such as remote controls, automatic doors, or custom finishes can enhance the usability and convenience of the lift.
Cost is another key factor. Set a budget and find lifts within that range, taking into account both the initial cost and long-term maintenance expenses. Finally, consider your aesthetic preferences. Think about how important the look of the lift is to you and how it will blend with your home’s decor. Some lifts offer customisation options to match the style of your home, ensuring that functionality and design go hand in hand.
