A Brief History History Of Wheelchair Ramp

Wheelchair Ramp Design and Construction

A wheelchair ramp is an important tool for helping your loved ones live independently in their home. However, if they aren't designed correctly they could be dangerous to use.

ADA regulations require level landings on any changes in direction, to avoid compound slopes. They also require 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 are able to comfortably navigate the structure. For example, the ramp slope cannot exceed the ratio 1:12 and must have landings that are level at any angle or change in the ramp's surface. It should also be constructed using treated lumber, which is more durable than lumber that is not treated and can weather precipitation better.

The ramp's top and bottom must be free of obstacles such as trees, bushes, or other structures that could hinder the user's safe passage. The surface of the ramp should be non-slip as well as hard. Certain municipalities require an anti-slip running surface on the entire length of the retractable ramp for wheelchair.

For the ramp frame choose treated lumber that is at least 4 inches wide. Create posts to anchor the ramp, ensuring that they are at least eight feet apart, and that they extend beyond the ground level. Spindles should be used to connect the posts with the railings of the ramp. This kind of connection is preferred because it minimizes the risk of a ramp operator falling off the edge of the ramp.

Then, you can build the ramp's frame using beams that measure 2 by 4 inches in size and joists at least 16 inch long. Make sure that the joists stand a minimum of 18 inches above the ground and are secured using joist hangers which are nails that grip the inside of the joists and prevent them from sliding out of alignment. Attach the ramp decking with a framing nailer.

Install an upper landing on the doorway to ensure wheelchair occupants can easily manage the doorswing. This landing should be large enough to provide at least 12 to 24 inches of "elbow space" on the handle side for out-swing doors. For in-swing doors, the landing must be at minimum 58 by 60 inches to allow for the threshold of the door and a person in a wheelchair who needs to move backwards through the doorway.

Install an elevated landing at every alteration in the direction of the ramp to prevent the requirement for wheelchairs to step on their brakes as they turn corners. A level landing makes it easier to move the ramp away from the way when needed to allow lawnmowers or other equipment can go under it.

Materials

Concrete, wood or aluminium can be used to build ramps for wheelchairs. A professional ramp installer can assist you in choosing the right option for your office or home. It is essential to take into consideration your specific needs and budget when selecting the materials used for the ramp. The ramp should be simple to maintain, and it should be safe for use. Some cities require that the ramp be paved with a non-slip surface.

Make sure to inquire with your local government for permits prior to building or purchasing any materials. Also, make sure to follow all local building codes. Making use of the incorrect materials or construction techniques can result in dangerous conditions for wheelchair users. You can find the most current construction requirements in your local building department of the government or library, or on the internet.

Wood ramps are typically the least expensive of ADA ramp materials, but they require more maintenance than other alternatives. The surface of wood ramps need to be regularly treated with a sealer to avoid rot and warping. Wood splinters can be a problem, and is particularly hazardous for people in wheelchairs. Wood ramps may also require additional support to ensure that the structure is standing and steady.

Concrete ramps are extremely durable and last for a long time however they can be expensive. They are also heavy, which requires more labor to install and makes moving the ramp when it's no longer needed difficult. Concrete ramps are strong enough to support the weight of power wheelchairs.

Aluminum ramps are less heavy and less expensive than steel or concrete. They also have the same durability, strength and resistance to corrosion. They are also more affordable than steel and iron, making them an excellent option for people on an extremely tight budget. Aluminum is eco-friendly because it is a part of the Earth's crust naturally and is able to be recycled.

The upper ramp's landing should be at least 3/8 inch of the threshold to allow for the smaller front wheels of wheelchairs to move over it without becoming stuck. Ramps with a gap greater than this do not meet ADA standards. It is also important to ensure that the ramp flows smoothly from the upper landing to the surface. The ramp's final section should have a beveled edge that will prevent wheelchairs from stopping abruptly at the point of leaving or entering a house.

Installation

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

There are a variety of factors to consider when choosing a adjustable wheelchair ramp ramp, including height, location and cost. The ramp should be located closest to the door to prevent unnecessary journeys. It should also be positioned at an elevation that is easily accessed by the person who is using it. It should be securely fixed to the floor and clear of obstructions, such as trees, cars parked 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 an edging surface that is smooth or rounded. In addition, they must be attached to the ramp and extend at least 12 inches beyond the ramp's edge. Handrails must be continuous if a ramp is designed with switchbacks or an L-shaped layout.

The length of a ramp is contingent on the incline, however there are a few common ramp types that can be used in all situations. For example the rubber threshold ramps for wheelchairs ramp is placed right on the edge of a curb or the threshold of a doorway while portable ramps can be moved from one spot to another and are available in a variety of sizes. Modular aluminum ramps can also be constructed on-site. These ramps are commonly used in commercial or public areas and are typically longer.

If you're considering a permanent ramp, be sure you check with the building department of your city to determine if you require permits. It is also a good idea to speak with an expert in mobility to determine which kind of ramp is best suited to your requirements and the space you have. In certain cases the installation of a permanent ramp can even increase the value of your home.

Maintenance

It's crucial to ensure your ramp for wheelchairs is maintained, especially if you are going to use it often. It is essential to conduct regular inspections and deal with any structural issues as they arise. This will ensure that the ramp is in compliance with all ADA requirements and is safe for all users.

Regularly cleaning wooden ramps is required to remove dirt and debris that could hinder access. Cleaning the ramp regularly will also prevent moisture from accumulating under the surface and leading to rot. Preservatives and stains for wood only work when the ramp has been thoroughly cleaned prior to application.

Wheelchair ramps are more challenging to maintain than other types of ramps, as they are more likely to experience wear and wear and tear. It is important to have the proper tools. To make sure that all fixings are secure and tight you'll need an appropriate set of screwdrivers as well as gauge spanners. You should also regularly inspect the handrails to see if there are signs of corrosion or damage. Over time, and with repeated use, it's possible that some bolts or fittings that are anchored on the handrails to come loose. This can pose an issue for anyone who is using the ramp.

It is also essential to make sure that the surface of the ramp is sufficiently grippy, especially in winter when conditions can be difficult. You'll need to clean away any dirt, leaves or other debris that might block and cause slippage. In addition, you'll want to apply a non-corrosive ice melt to the ramp surface before winter arrives to prevent slipping and injury.

If you're planning to use your ramp throughout the winter months, you should consider purchasing traction wheels or "snow tires" for your wheelchair. These wheels are designed to better track on slippery and snowy surfaces. They will allow you to stay on your ramp more effectively than standard wheelchair threshold ramp tires. You can also use heating tape or pads to melt the ice and snow on the ramp before it builds up.
