electric wheelchair ramps for cars (blog) Ramp Design and Construction

A wheelchair ramp is a vital 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 landings to be level at every shift in direction to avoid compound slopes. They must also have an accessible surface for wheelchair users.

Design

The ramp's design must meet the Americans with Disabilities Act standards so that wheelchairs are able to maneuver the structure with ease. For example, the ramp slope cannot exceed a ratio of 1:12 and must have level landings at any angle or shift in the ramp's surface. It must be constructed of treated lumber which is more durable than lumber that is not treated and is able to withstand rain better.

The ramp's top and bottom should be free of obstructions like trees, bushes, or other structures which could interfere with the user's safe passage. The ramp's surface should be non-slip as well as hard. Certain municipalities require an anti-slip running surface along the ramp's entire length.

For the frame of the ramp choose treated lumber that is at minimum four inches wide. To secure the ramp, build posts that are at least 8 feet apart and extend to below the level of the ground. Spindles should be used to connect the posts to the railings of the ramp. This type of connection decreases the chance of a ramp user falling off the ramp.

Then, build the ramp's frame using beams 2 by 4 inches in size and joists that are at minimum 16 inches long. Make sure that the joists are at a minimum of 18 inches above the ground and that they're secured with hangers for joists, which are nails that hold the inside of the joists and prevent them from slipping out of place. Attach the ramp decking with framing nails.

Install an upper landing on the doorway so that the wheelchair-bound occupants are able to easily maneuver the doorswing. This landing should provide 12 to 24 inches on the handle side of the doors that swing out. For doors with in-swing, the landing must be at least 58 inches by 60 inches to accommodate the door's threshold and the person in movable wheelchair ramp who must roll backward through the doorway.

Install a level landing when changing the direction of the ramp, to avoid wheelchairs from having to slam their brakes into corners. A level landing allows you to move the ramp out of the way if necessary so that lawnmowers and other equipment can slide under it.

Materials

The material used to construct ramps for wheelchairs could be either concrete, wood or aluminum. A professional ramp installer will help you select the most suitable option for your office or home. It is crucial to think about your individual needs and budget when selecting the materials for the ramp. The ramp should be simple to maintain and should be safe to use. Some cities require the ramp to be covered with a non-slip surface.

Be sure to inquire with your local government for permits before you begin building or purchasing materials. Also, be sure to follow all local building codes. Making use of the wrong materials or construction methods can lead to dangerous conditions for wheelchair users. You can find up-to-date construction guidelines in your local building department of the government, library or on the internet.

Wood ramps are typically the least expensive of ADA ramp materials, but they require more care than other options. Wood ramps must be maintained regularly using a sealer in order to stop decay. Wood can splinter and can be hazardous for those using wheelchairs. Wood ramps might require additional support to ensure the structure remains upright and stable.

Concrete ramps are extremely durable and long-lasting, but they can be expensive. They are heavy, which means that more work is required to construct them and can make it difficult to move the ramp after it is it is no longer required. Concrete ramps are strong enough to withstand the weight of power wheelchairs.

Aluminum ramps are less heavy and less expensive than steel or concrete. They also have the same strength, durability and corrosion resistance. They are also cheaper than iron and steel which makes them a great option for people on budgets. Aluminum is also green, since it is naturally present in the Earth's crust, and can be recycled.

The ramp's upper landing needs to be in a level area or within 3/8 inches of the threshold of the door, allowing wheelchairs with smaller wheels to pass across the ramp without getting stuck. Ramps with gaps greater than this do not comply with ADA standards. It is also important to ensure that the ramp flows smoothly from the upper landing to the ground surface. The ramp's final section should be curved to prevent wheelchairs from stopping abruptly when they leave or enter a house.

Installation

A ramp for wheelchairs is a plane inclined ramp that can be used as an alternative or in addition to stairs. It allows wheelchair ramp folding users as well as those who use carts or strollers to reach areas that would otherwise be difficult to access.

There are several considerations when choosing a gardhom wheelchair ramps ramp, including location, height and cost. The ramp should be located closest to the door to prevent unnecessary travel. It should be set at a level that the person using it can be able to easily access it. It should be firmly anchored to the floor and clear of any obstructions such as car parks, shrubs or other obstacles.

ADA regulations require that ramps have handrails on either side. The rails must be at least 36" apart and have an even or smooth gripping surface. They should also be connected to the edge of the ramp, and extend 12 inches over it. If the ramp has switchbacks 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, but there are several standard ramps that can be used in most situations. A threshold ramp, for example is placed flush against the lip of the curb or threshold of the doorway. Portable ramps are however, can be moved to another place and come in different sizes. Modular aluminum ramps can also be assembled on-site. These ramps are usually used in public or commercial areas and are usually longer.

Check with your city's construction department to determine if a permit is required for an ongoing ramp. You should also speak to a mobility specialist about the type of ramp that is best for your needs and space. In some instances, installing permanent ramps can improve the value of your house.

Maintenance

It is crucial to keep your ramp for wheelchairs in good condition particularly if it is going to be used regularly. You'll need to conduct regular inspections and fix any structural issues when they arise. This will help ensure the ramp complies with all ADA requirements and is safe for all users.

Regularly cleaning wooden ramps is necessary to remove dirt and debris that may block access. Keeping the ramp clean will also prevent moisture from trapping under the surface and leading to the onset of rot. Preservatives and stains for wood only work if the ramp has been thoroughly cleaned prior to applying.

fold-out wheelchair ramp for van ramps are more challenging to maintain than other types of ramps, as they are more likely to experience wear and tear. It is essential to have the proper tools. A set of gauge spanners as well as screwdrivers will be essential for making sure all fixings are tight and secure. It's also worth regularly inspecting the handrails to make sure they are in good shape and have no 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 come loose, which can be a major safety concern for those using the ramp.

Another crucial aspect is to ensure that the ramp's surface has sufficient grip, particularly in winter when conditions can be challenging. You will need to sweep away any dirt, leaves or other debris that could block the ramp and cause slippage. You'll also need to apply an ice melt that's non-corrosive to the ramp surface to avoid injuries and slipping.

If you're planning to use your ramp during winter, consider investing in wheels for traction or "snow tires" for your wheelchair. These wheels are made to better track on slippery and snowy surfaces. They will help you remain on your ramp more effectively than normal wheelchair tires. Alternatively, you can place heating pads or tape along the ramp's surface to help melt snow and ice before it builds up.
