Wheelchair Ramp Design and Construction

A ramp for wheelchairs can be a valuable aid to help your loved ones live more independently at home. If they are not designed properly, they are unsafe to use.

ADA regulations require level landings on any changes in direction to prevent compound slopes. They must also have a surface that is gripping for wheelchair car ramp users.

Design

The ramp design must meet the Americans with Disabilities Act (ADA) standards to ensure that wheelchairs easily navigate the structure. For instance, the ramp's slope cannot exceed the ratio 1:12 and must have landings that are level upon 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 is able to withstand rain better.

The ramp's bottom and top should be free of obstacles, such as trees, bushes, or other structures which could hinder the user's safe passage. In addition the ramp's surface must be non-slip and hard. Some municipalities require that the entire ramp be covered with a non-slip surface.

For the ramp frame, use treated lumber that is at least four inches wide. Make posts to support the ramp, ensuring they are at minimum eight feet apart and that they extend above ground level. The posts must then be connected with the ramp's railings by using spindles. This kind of connection is preferred since it decreases the chance of the ramp operator falling off the side of the ramp.

Then, build the frame of the ramp using beams 2 by 4 inches in length and Joists that are at least 16 inches long. Make sure that the joists stand a minimum of 18 inches above ground level and are secured using joist hangers which are nails that hold the inside of the joists and stop them from sliding off the ground. Attach the ramp decking using a framing nailer.

Add an upper landing near the doorway to allow 6ft wheelchair ramp - check out this blog post via mobility-scooters-uk09987.answerblogs.com - occupants to manage the doorswing with ease. This landing should have 12 to 24 inches on the handle side of the doors that swing out. The landing for doors with in-swinging should be 58 x 60 in order to accommodate the threshold of the door and a wheelchair user who has to go backwards through the doorway.

Install a level landing whenever you change in ramp direction to avoid the necessity for wheelchairs to hit on their brakes when turning corners. Adding a level landing also allows you to move the ramp out of the way if necessary so that lawnmowers and other equipment can go under it.

Materials

Aluminium, concrete, or wood can be used to build ramps for wheelchairs. A professional ramp installation service will help you choose which one is suitable for your business or home. It is important to consider your individual needs and budget when selecting the materials for the ramp. The ramp should be easy to maintain, and it should be safe to use. Certain cities require that the ramp be paved with a non-slip surface.

Be sure to inquire with your local government for permits prior to building or purchasing any materials. Also, be sure to adhere to all local building codes. Incorrect construction materials or techniques could create hazardous conditions for wheelchair users. You can find current construction regulations in your local government building department or library, or on the internet.

Wood ramps can be the least expensive alternative for ADA ramp materials. However they need more maintenance. The surface of wood ramps should be treated regularly with a sealer to prevent rot and warping. Wood splinters can be a problem, and can be especially hazardous for people in wheelchairs. Wood ramps also require additional support to maintain the structure.

Concrete ramps can be expensive however they are durable and long-lasting. They are heavy, which means more labor is required to put in them, and they can make it difficult to move the ramp once it is no longer required. Concrete ramps can handle the weight of heavy power wheelchairs.

Aluminum ramps are lighter than concrete or steel however they possess the same strength and corrosion resistance. They are also less expensive than steel or iron and are an ideal choice for those on a tight budget. Aluminum is environmentally friendly because it is found in the earth's crust naturally, and is recyclable.

The ramp's upper landing needs to be at a level level, or within 3/8 inches of the threshold of the door in order for wheelchairs with smaller wheels to pass over the ramp without becoming stuck. Ramps with a gap that is larger than this will not meet ADA standards. Also, make sure that the ramp transitions smoothly between the upper landing and the ground. The last section of the ramp should be a a beveled transition to avoid the abrupt stop of wheelchairs when they enter or leave a dwelling.

Installation

A ramp for wheelchairs is a sloped plane ramp that can be used as an alternative or in the place of steps. It allows 10ft wheelchair ramp users and people who use strollers or carts to get around areas that are otherwise difficult to reach like an entranceway or a set up of steep steps.

There are a variety of factors to consider when selecting a ramp for wheelchairs that should be considered, including the location, height and cost. The ramp should be placed close to the door to prevent unnecessary travel. It should also be placed at a level that is easy to navigate by the person using it. It should be securely anchored to the floor and free of obstructions, such as trees, cars parked or other obstacles.

ADA regulations require that ramps have handrails on either side. The rails should be at minimum 36" apart and have a smooth or rounded gripping surface. They should also be connected to the edge of the ramp, and extend 12 inches beyond the ramp. Handrails must be continuous when the ramp is designed with switchbacks or in an L-shaped layout.

The length of a ramp varies on the slope, however there are a few basic ramps that can be used in all situations. A threshold ramp, for instance, sits flush against the curb's lip or the threshold of the doorway. Portable ramps are, however, can be moved to another location and are available in a variety of sizes. Modular aluminum ramps may also be built on-site. These ramps are typically employed in public or commercial areas and are typically longer.

If you are considering a permanent ramp, be sure to check with the building department of your city to see if you need a permit. Also, you should consult an expert in mobility about the kind of fold ramp for wheelchair that will work best for your needs and space. In some cases installing an ongoing ramp could increase the value of your home.

Maintenance

It's important to make sure your ramp for wheelchairs is maintained, especially if you will be using it often. You'll need to perform regular inspections and fix any structural issues when they arise. This will help ensure that the ramp complies with all ADA requirements and is safe for all users.

Wooden ramps require frequent cleaning to get rid of dirt and debris that may block access. Cleaning the ramp regularly will also prevent moisture from accumulating under the surface and causing decay. The wood preservatives or stains only work only if the ramp is thoroughly cleaned before application.

retractable wheelchair ramp ramps are more difficult to maintain than other ramps due to the fact that they are more likely wear and tear. It is important to have the proper tools. A set of gauge spanners and screwdrivers will be vital to ensure that all fixings are secure and secure. It's also worth regularly inspecting the handrails to ensure they are in good shape and have no signs of corrosion or damage. It is possible that over time, with repeated usage some of the fittings and bolts which hold the handrails in place could loosen and cause an extremely dangerous risk for people who use the ramp.

It is also important to make sure that the surface of the ramp is grippy enough especially in winter, when the conditions are difficult. You will need to sweep off any leaves, dirt or other debris that could obstruct and cause slippage. Additionally, you'll need to apply a non-corrosive ice melt on the ramp surface before winter arrives to prevent slips and injury.

You should consider buying "snow tires" or traction wheels for your wheelchair if plan to use it throughout the winter. These wheels are made to better track on snowy and uneven surfaces. They can help you remain on your ramp longer than normal wheelchair tires. You can also use heating tape or pads to melt the ice and snow on the ramp prior to it builds up.
