Wheelchair Ramp Design and Construction

A wheelchair ramp can be an important aid to assist your loved ones live more independently at home. If they are not designed properly they could be unsafe to use.

ADA regulations require level landings at all changes in direction to avoid compound slopes. They must also have a surface that is gripping for wheelchair users.

Design

The ramp's design must be in line with the Americans with Disabilities Act (ADA) standards to ensure that wheelchairs can easily navigate the structure. For example, the ramp slope cannot exceed a ratio of 1:12 and must have level landings at any angle or change in the ramp's surface. It must also be constructed using treated lumber that is more durable than untreated and is able to withstand rain better.

The ramp's top and bottom must be free of obstacles like trees, bushes, or other structures that could hinder the user's safe passage. The ramp's surface should be non-slip as well as hard. Some municipalities require that the entire ramp be coated with an anti-slip surface.

For the ramp frame, use treated lumber that is at least four inches wide. Make posts to support the ramp, making sure they are at least eight feet apart, and that they extend beyond the level of the ground. Spindles are the best way to connect the posts to the railings of the car ramp for wheelchair. This kind of connection minimizes the chance of a ramp user falling off the ramp.

Next, construct the frame of the ramp using beams 2 by 4 inches in size and joists at least 16 inch long. The joists should be at minimum 18 inches above the ground and secured by hangings for joists which are nails that sit within the joists, preventing them from sliding. Attach the ramp decking using framing nails.

Include an upper landing in the doorway to ensure the wheelchair-bound occupants are able to easily maneuver the doorswing. The landing should be wide enough to allow at least 12 to 24 inches of "elbow space" on the handle side of out-swing doors. For doors with in-swing the landing should be at least 58 by 60 inches to allow for the threshold and a person using a wheelchair who needs to roll backward through the doorway.

Install a level landing when changing the direction of the ramp to prevent wheelchairs from having to hit their brakes into corners. A level landing also makes it easier to move the ramp away from the way if necessary so that lawnmowers and other equipment can go under it.

Materials

The material used to build the ramp for wheelchairs can be wood, concrete or aluminum.

When choosing the material for the lightweight ramp for wheelchair, it is crucial to consider your budget and requirements. The ramp should be simple to maintain and safe to use. Some cities require the ramp to be covered with a non-slip surface.

Before you purchase any building materials or begin building, be sure you have the required permits from your local government, and ensure that you adhere to all building codes within your area. The wrong materials or construction techniques can create dangerous conditions for wheelchair users. You can find up-to-date construction regulations in your local government building department library, or on the internet.

Wood ramps can be the least expensive option for ADA ramp materials. However, they require more maintenance. Wood ramps need to be regularly treated with a sealer in order to prevent the onset of rot. Wood can splinter and can be dangerous for people who use wheelchairs. Wood ramps might also require additional support to ensure that the structure is in place and stable.

Concrete ramps are expensive but they are also durable and last for a long time. They are heavy, which means that more labor is required to install them and can make it difficult to move the ramp after it is no longer needed. Concrete travel ramps for wheelchairs are sturdy enough to support the weight of power wheelchairs.

Aluminum ramps weigh less than steel or concrete, but they have the same strength and resistance to corrosion. They are also cheaper than steel and iron which makes them a great option for those with an extremely tight budget. Aluminum is a green choice because it is a part of the earth's crust naturally and is able to be recycled.

The ramp's upper landing needs to be level or within 3/8 inches of the threshold of the door to allow wheelchairs with smaller wheels to pass over the ramp without becoming stuck. Ramps that have a gap higher than this meet ADA standards. You should also ensure that the ramp moves smoothly between the upper landing and the ground. The last section of the ramp should be a a beveled transition to avoid an abrupt stop for wheelchairs when they exit or enter a dwelling.

Installation

A ramp for wheelchairs is an inclined plane that is erected as an addition or in lieu of steps. It allows wheelchair users, as well as people who use carts or strollers to get into areas that would otherwise be difficult to access.

There are a variety of factors to consider when choosing a wheelchair ramp such as location, height and cost. The ramp should be located as close as possible to the door to avoid unnecessary traveling. It should be placed at a height that the person using it is able to be able to easily access it. It should also be properly anchored to the ground and free of obstructions like shrubbery or parked cars.

ADA regulations require that ramps are equipped with handrails either side. The rails must be at least 36 inches apart and have the gripping surface smooth or rounded. They should also be connected to the edge of the ramp and extend 12 inches beyond it. If a ramp has switchesbacks or an L-shaped layout handrails must be in continuous use between the ramp's runs.

The length of a ramp depends on the incline, however there are a few common ramps that are suitable for most situations. A threshold ramp, for instance, sits flush against the curb's lip or the threshold of the doorway. Portable ramps, however are able to be moved to another location and come in different sizes. Modular aluminum ramps may also be assembled on-site. These ramps are typically used in public or commercial areas and are typically longer.

Contact your city's construction department to determine the need for a permit for a permanent ramp. You should also speak to an expert in mobility to determine the kind of ramp that works best for your needs and space. In some cases installing an all-weather ramp can boost the value of your home.

Maintenance

It is important to keep your ramp for wheelchairs in good condition, especially if it will be used regularly. You'll need to conduct regular inspections and deal with any structural issues as they arise. This will ensure that the ramp complies with all ADA requirements and is safe for all users.

Regular cleaning of wooden ramps is necessary to remove dirt and debris that could hinder access. Cleanliness of the ramp will also stop moisture from accumulating under the surface and causing decay. Preservatives and stains for wood can only be effective when the ramp has been thoroughly cleaned prior to application.

Wheelchair ramps are more challenging to maintain than other kinds of ramps, as they are more prone to wear and tear. It is essential to have the right tools. A set of gauge spanners as well as screwdrivers are vital to ensure that all fixings are secure and secure. Also, you should regularly check the handrails for signs of damage or corrosion. It's possible that over time, and with repeated use, some of the bolts and fittings that secure the handrails may loosen and pose an extremely dangerous risk for people who use the ramp.

Another crucial aspect is to ensure that the surface of the ramp is grippy, especially during winter when conditions may be challenging. You'll need to remove any leaves, dirt and other debris that can hinder the surface and cause slippage. You'll also need to apply an ice melt that is non-corrosive to the ramp surface to prevent injuries and slipping.

Think about buying "snow tires" or traction wheels for your wheelchair if plan to use it throughout the winter. They're specifically designed to aid in tracking on uneven surfaces and snow which is why they'll be more efficient than standard wheelchair tires in keeping you on the ramp. You can also use heating tape or pads to melt the ice and snow on the ramp prior to it accumulates.
