Wheelchair Ramp Design and Construction

A ramp for wheelchairs is a valuable device to help 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 at all changes in direction to avoid compound slopes. They also need to provide a gripping surface for wheelchair users.

Design

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

The ramp's top and bottom should be free of obstacles like trees or bushes, or any other structures that could hinder the user's safe passage. Additionally, 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 choose treated lumber that is at least four inches wide. Create posts to anchor the ramp, making sure they are at least eight feet apart and that they extend above ground level. Spindles should be used to connect the posts to the ramp's railings. This type of connection decreases the chance of a ramp operator falling off the ramp.

Then, construct the ramp's frame using joists that are at most 16 inches long and beams of 2 by 4 inches. Make sure that the joists stand a minimum of 18 inches above the ground and that they are secured with Joist hangers which are nails that bind the inside of the joists to prevent them from slipping out of alignment. Attach the ramp decking using a framing nailer.

Add an upper landing to the doorway to ensure wheelchair users can easily navigate the doorswing. This landing should provide 12 to 24 inches on the handle side of out-swinging doors. The landing for doors with in-swinging must be 58 by 60 in order to accommodate the threshold ramps for wheelchairs of the door as well as wheelchair kerb ramp users who need to walk backwards in the doorway.

Install a level landing at any alteration in the direction of the small ramp for wheelchair to avoid the requirement for wheelchairs to step on their brakes while turning corners. A level landing makes it easier to move the ramp out of the way, if needed to allow lawnmowers or other equipment can slide under it.

Materials

Aluminium, wood, or concrete can be used to construct ramps for wheelchairs. A professional ramp installer will help you select the most suitable option for your office or home. When choosing the material for the ramp, it is crucial to consider your budget and specific needs. The ramp should be easy to maintain, and it must be safe to use. Certain cities require that the ramp be paved with a non-slip surface.

Be sure to check with your local government for permits prior to building or purchasing materials. Also, make certain to follow the local building codes. Utilizing the incorrect materials or construction techniques could result in hazardous conditions for wheelchair users. You can get the most up-to-date information about construction regulations at the building department of your local government office or library, or on the internet.

Wood ramps are often the most affordable option for ADA ramp materials. However they need more maintenance. Wood ramps must be maintained regularly using a sealer in order to avoid decay. Wood can split, which can be especially hazardous for people in wheelchairs. Wood ramps can also need additional support to maintain the structure.

Concrete ramps are extremely durable and last for a long time, but they can be expensive. They are heavy, which means more work is required to construct them, and they can make it difficult to move the ramp once it is no longer required. Concrete ramps are sturdy enough to support the weight of power foldable wheelchair ramp ramps (browse this site) wheelchairs.

Aluminum ramps are lighter and more affordable than steel or concrete. They also have the same durability, strength and corrosion resistance. They are also cheaper than iron or steel and are a great option for those on a tight budget. Aluminum is environmentally friendly since it is found in 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 move over the ramp without getting stuck. Ramps that have gaps greater than this will not meet ADA standards. Also, ensure that the ramp is smooth transitioning from the upper landing to the ground surface. The last section of the ramp should have beveled transitions to avoid the abrupt stop of wheelchairs when they enter or exit an apartment.

Installation

A wheelchair ramp is a sloped plane ramp that can be used as an alternative to or in addition to steps. It lets wheelchair ramps vans users and those who use strollers or carts to access areas that are otherwise difficult to reach like the front door or a set of sloping steps.

There are many factors to consider when selecting a ramp for wheelchairs, including height, location and cost. The ramp should be placed as close as possible to the door to avoid unnecessary journeys. It should also be positioned at an angle that is easy to use by the person using it. It should also be properly fixed to the ground and clear of obstructions, such as the trees or cars parked.

ADA regulations require that ramps must have handrails on either side. These rails should be at 36 inches apart and have a gripping surface that is smooth or rounded. In addition, they must be attached to the ramp and extend at least 12 inches beyond the ramp edge. If the ramp has switchbacks or an L-shaped layout handrails should be a continuous length between the ramp's edges.

The length of the ramp is determined by the slope. However, there are some common ramp types that can be used for most situations. For instance the threshold ramp is 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 a variety of sizes. There are also aluminum ramps that are modular that can be assembled on the spot. These ramps are typically used in commercial or public areas and are usually longer.

If you are considering a permanent ramp, be sure you check with your city's building department to determine if you'll need permits. It is also advisable to speak with an expert in mobility about the type of ramp that works best for your needs and space. In some cases installing a permanent ramp can even increase the resale value of your home.

Maintenance

It's crucial to ensure your wheelchair ramp is well maintained, especially if are going to use it often. You'll need to conduct regular inspections and repair any structural issues that develop. This will ensure that the ramp meets all ADA requirements, and is safe for users.

Wooden ramps require regular cleaning to remove debris and dirt that could block access. Keep the ramp clean to avoid moisture from accumulating beneath the surface. This can lead to decay. The wood preservatives or stains will only work only if the ramp is thoroughly cleaned before application.

Wheelchair ramps are more difficult to maintain than other ramps as they are more prone to wear and tear. It is crucial to have the proper tools. A good set of gauge spanners as well as screwdrivers will be vital to ensure that all fixings are tight and secure. Also, you should regularly check the handrails for signs damage or corrosion. It is possible that over time, with repeated usage and use, the fittings and bolts that secure the handrails may come loose and cause an extremely dangerous risk for those who use the ramp.

It is also crucial to make sure that the surface of the ramp is grippy enough particularly in winter, when the conditions are challenging. You'll need to remove any leaves, dirt and other debris that could hinder the surface and cause slippage. In addition, you'll want to apply a non-corrosive ice melt to the ramp's surface prior to winter arrives to prevent slips and injury.

If you're planning on using your ramp during winter, consider investing in wheels for traction, or "snow tires" for your wheelchair. They're specifically designed to aid in tracking on snow and uneven surfaces and are therefore more effective than standard wheelchair tires at helping you stay on the ramp. Alternately, you can put heating pads or tape along the ramp's surface to melt ice and snow before it accumulates.
