Wheelchair Ramp Design and Construction
A ramp for wheelchairs can be a valuable device to assist a loved one live more independently at home. If they are not designed correctly they could be unsafe to use.
ADA regulations require level landings on any changes in direction to prevent compound slopes. They also must provide a surface that is gripping for wheelchair users.
Design
The ramp design must meet the Americans with Disabilities Act (ADA) standards to ensure that wheelchairs are able to easily navigate the structure. For example, the ramp slope cannot exceed a ratio of 1:12 and must have landings that are level upon any change in direction or change in the ramp's surface. It must also be constructed out of treated lumber that is more robust and weathers precipitation far better than untreated lumber.
The top and bottom of the ramp should be free of obstructions like bushes, trees or other structures that can hinder the safe movement of the ramp's user. The ramp's surface must be non-slip and hard. Some municipalities require that the entire ramp be covered with a non-slip surface.
Make use of treated lumber that is at minimum four inches wide for the frame of the ramp. Make posts to support the ramp, making sure they are at least eight feet apart and that they extend beyond the ground level. The posts should then connect to the ramp's railings using spindles. This type of connection is recommended because it reduces the risk of a ramp operator falling off the side of the ramp.
Then, construct the frame for the ramp using joists that are at most 16 inches long and beams of 2 by 4 inches. Make sure that the joists are at a minimum of 18 inches above ground level and that they are secured with joist hangers, which are nails that hold the inside of the joists to prevent them from sliding out of place. Attach the ramp decking with a framing nailer.
Install an upper landing close to the doorway, allowing people with disabilities to navigate the doorswing easily. This landing should provide 12 to 24 inches on the handle side of the doors that swing out. The landing for in-swinging doors must be 58 by 60 inches in order to accommodate the threshold of the door and a wheelchair user who needs to go backwards through the doorway.
Install a level landing at any change in the direction of the ramp to prevent the requirement for wheelchairs to step on their brakes when turning corners. A level landing makes it simpler to remove a ramp of the path if needed, so that equipment such as lawnmowers can be able to pass underneath it.
Materials
The material used to construct a
retractable wheelchair ramp ramp can be made of wood, concrete or aluminum. A professional ramp installation company will help you choose the best option for your home or business. When choosing the material to use for the ramp, it's important to consider your budget and specific needs. The ramp should be simple to maintain and safe for use. Some cities require the ramp to be paved with a non-slip surface.
Before you purchase any materials or begin construction, make sure you have the required permits from your local authority and ensure that you adhere to all building codes within your area. Incorrect construction materials or techniques can create dangerous conditions for wheelchair users. You can find up-to-date construction requirements in your local building department library, or on the internet.
Wood ramps are often the least expensive of ADA ramp materials, however they require more maintenance than other options. The surface of wood ramps need to be regularly treated with a sealer to prevent rot and warping. Wood can splinter and be dangerous for people using wheelchairs. Wood ramps might require additional support to keep the structure in place and stable.
Concrete ramps are extremely durable and last for a long time, but they can be expensive. They are also heavy, which requires more work to construct and makes moving the ramp when it's no longer required difficult. Concrete ramps can handle the weight of powerful wheelchairs.
Aluminum ramps weigh less than steel or concrete however they possess the same strength and resistance to corrosion. They are also less expensive than iron and steel which makes them a great option for people on budgets. Aluminum is also environmentally friendly because it is naturally present in the Earth's crust, and can be recycled.
The upper landing of the ramp should be level or within 3/8 inch of the threshold in order to allow the front wheels of smaller wheelchairs to pass over it without getting stuck. Ramps that have a gap higher than this comply with ADA standards. It is also important to ensure that the ramp moves smoothly between the upper landing and the ground. The final section of the ramp should be a an angled transition to prevent an abrupt stop for wheelchairs when they enter or leave the dwelling.
Installation
A ramp for wheelchairs is a sloped plane that can be installed as an alternative or in the place of steps. It allows wheelchair users and those who use carts or strollers to access areas that are otherwise difficult to access.
There are a variety of factors to consider when choosing a ramp for a wheelchair such as size, location, and height. Ideally, a ramp should be situated near the door as it is possible to avoid unnecessary travel. It should be set at a height that the person using it is able to easily walk on it. It should be securely anchored to the floor and free of any obstructions such as shrubbery, parked cars or other obstacles.
ADA regulations stipulate that ramps must are equipped with handrails either side. These rails should be at least 36 inches apart and have a gripping surface that is rounded or smooth. They must also be anchored to the edge of the ramp and extend 12 inches beyond it. If the ramp has switchesbacks or an L-shaped layout, handrails should be a continuous length between the ramp's edges.
The length of a ramp is contingent on the incline, however there are a few common ramp types that are suitable for most situations. For instance the
rubber threshold ramps for wheelchairs ramp is placed flush along the lip of a curb, or the threshold of a doorway, while ramps that are portable can be moved from one place to another and are available in many different sizes. There are also aluminum ramps with modular design that can be assembled on site. These are usually used for commercial or public areas and are typically longer than the threshold and portable ramps.
Check with your city's construction department to determine if a permit is required for an ongoing ramp. It is recommended to consult a mobility specialist to find out what type ramp will be the most suitable for your requirements and the space you have. In some cases, installing permanent ramps can improve the value of your home.
Maintenance
It is crucial to keep your
electric ramp for wheelchair for wheelchairs in good condition especially if it will be used frequently. It is essential to conduct regular inspections and deal with any structural issues as they occur. This will ensure that the ramp is in compliance with all ADA requirements, and is safe for all users.
Wooden ramps require regular maintenance to remove dirt and debris that could block ez access wheelchair ramp (

Wheelchair ramps are more difficult to maintain than other ramps as they are more susceptible to wear and tear. It is essential to have the right tools. To make sure that all fixings are secure and tight you'll need an excellent set of screwdrivers and gauge spanners. It is also important to regularly check the handrails to make sure they are in good working order and have no signs of damage or corrosion. As time passes, and with repeated use, it's not uncommon for some of the bolts or fittings the handrails to come loose. This can be an unsafe situation for anyone using the ramp.
Another crucial aspect is to ensure that the ramp's surface has enough grip, especially during winter when conditions may be a challenge. You'll need to clean away any leaves, dirt and other debris that may obstruct the surface and cause slippage. Additionally, you'll need to apply an ice melt that is not corrosive to the ramp's surface prior to winter arrives to prevent slipping and injury.
If you're planning to use your ramp throughout the winter months, you should consider purchasing wheels for traction, or "snow tires" for your wheelchair. These wheels are made to track better on slippery and snowy surfaces. They will allow you to remain on your ramp for longer than regular wheelchair tires. Alternatively, you can place heating pads or tape on the ramp's surface to help melt ice and snow before it accumulates.
