Wheelchair Ramp Design and Construction

A ramp for wheelchairs is an effective tool to help the person you love independently at home. If they are not designed properly, they are unsafe to use.

ADA regulations require level landings at any changes in direction to prevent compound slopes. They also require an accessible surface for wheelchair users.

Design

The ramp's design has to meet the Americans with Disabilities Act (ADA) standards to ensure that wheelchairs can comfortably navigate the structure. For instance, the ramp's slope should not exceed the ratio 1:12 and must have landings that are level upon any direction change or shift in the ramp's surface. It also must be constructed from treated lumber which is more durable and can withstand precipitation much better than untreated lumber.

The ramp's top and bottom should be free of obstacles, such as trees or bushes, as well as other structures which could interfere with the safety of the user. 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 frame of the ramp Choose treated lumber that is at least 4 inches wide. To secure the ramp, build posts that are at least 8 feet apart and extend beyond ground level. The posts must then be connected with the ramp's railings by using spindles. This type of connection decreases the risk of a ramp operator falling off the ramp.

Then, build the frame for the ramp using joists that are at least 16 inches long and beams that measure 2 by 4 inches. The joists must be at minimum 18 inches above the ground and secured using joist hangings, which are nails that sit inside the joists to prevent them from sliding. Attach the ramp decking with framing nails.

Add an upper landing near the doorway, allowing wheelchair 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. For doors that swing in the landing should be at least 58 by 60 inches to allow for the threshold of the door and a person using a wheelchair who needs to walk backwards through the doorway.

Install an elevated landing at every alteration in the direction of the ramp to prevent the need for wheelchairs to slam on their brakes as they turn corners. A level landing makes it easier to remove a ramp of the path if needed, so that lawnmowers and other equipment can move under it.

Materials

Concrete, wood or aluminium can be used to build a wheelchair ramp. A professional ramp installation service will help you choose which is best for your business or home. It is important to consider your specific needs and budget when selecting the materials used for the ramp. The ramp should be easy to maintain and should be safe for use. Certain cities require that the ramp be paved with an anti-slip surface.

Be sure to inquire 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 can result in dangerous conditions for wheelchair users. You can find current construction guidelines in your local building department library, or on the internet.

Wood ramps are usually the most affordable of ADA ramp materials, but they require more maintenance than other alternatives. The wood ramp's surface must be regularly treated with a sealer to avoid rot and warping. Wood can split and be dangerous for people using wheelchairs. Wood ramps may also require extra support to keep the structure in place.

Concrete ramps can be costly however they are durable and last for a long time. They are also heavy, which means more effort to install and makes moving the ramp after it's no longer required difficult. Concrete ramps can withstand the weight of powerful 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 less expensive than steel and iron, making them an excellent option for people on budgets. Aluminum is also environmentally friendly, since it is found naturally in the Earth's crust, and can be recycled.

The ramp's upper landing needs to be level, or within 3/8 inches of the threshold of the door, allowing wheelchairs with smaller wheels to go over the ramp without becoming stuck. Ramps that have gaps greater than this will not be able to meet ADA standards. It is also important to ensure that the ramp flows smoothly from the upper landing to the surface. The final section of the ramp must have a an angled transition to prevent the abrupt stop of wheelchairs when they enter or exit the dwelling.

Installation

A wheelchair ramp is an inclined plane that is used as an addition or instead of steps. It allows retractable wheelchair ramps users, as well as people who use carts or strollers to access areas that are otherwise difficult to access.

When selecting a wheelchair access ramp, there are many factors to consider, including the location, height and cost. The ideal is for a ramp to be located close to the door as is possible to avoid unnecessary transportation. It should also be placed at a level that is easily accessed by the person who is using it. It should also be fixed to the ground and clear of obstructions, such as shrubbery or parked cars.

ADA regulations require metal ramps for wheelchairs to have handrails on either side. The rails must be at minimum 36" apart and have an even or smooth gripping surface. They must also be anchored to the edge of the ramp, and extend 12 inches over it. If the ramp has switchesbacks or an L-shaped layout handrails must be in continuous use between the ramp's edges.

The length of a ramp depends on the slope, however there are several common ramp types that can be used in most situations. A threshold ramp, for instance is placed flush against the lip of the curb or threshold of the doorway. Portable ramps are however they can be moved to a different location and are available in different sizes. There are also aluminum ramps that are modular that can be built on site. These ramps are typically used in commercial or public areas and are usually longer.

If you're considering a permanent ramp, be sure you check with your city's building department to determine if you require permits. It is also advisable to speak van with wheelchair ramp an expert in mobility about the kind of ramp that works best for your space and needs. In some cases the installation of permanent ramps can increase the value of your house.

Maintenance

It's important to make sure your rubber wheelchair ramps for home ramp is well maintained, especially if are going to use it frequently. You'll need to perform regular inspections, and fix any structural issues that arise. This will ensure that the ramp is in compliance with all ADA requirements and is safe for all users.

Wooden minivan ramps for wheelchairs require regular cleaning to remove dirt and debris that could block access. Keep the ramp clean to avoid moisture from building up under the surface. This can cause decay. Preservatives and stains for wood only work effectively if the ramp is completely clean before application.

Wheelchair ramps can be more challenging to maintain than other types of ramps, as they are more prone to wear and wear and tear. The most important thing is to ensure you have the appropriate tools for the job. A set of gauge spanners and screwdrivers are vital to ensure that all fixings are tight and secure. You should also regularly inspect the handrails to see if there are signs of corrosion or damage. It's possible that, over time, as they are used repeatedly some of the bolts and fittings that secure the handrails may loosen and cause a serious safety risk for those using the ramp.

It is also important to ensure that the surface of the ramp is grippy enough especially in winter, when the conditions can be difficult. You will need to sweep away any dirt, leaves or other debris that might block and cause slippage. Additionally, you'll need to apply a non-corrosive ice melt to the ramp's surface before winter arrives to avoid slips and injury.

Consider buying "snow tires" or traction wheels for your wheelchair if you plan to use it throughout the winter. These are specifically designed to offer better tracking on snow and uneven surfaces, so they'll be more effective than standard wheelchair tires at keeping you on the ramp. You can also place heating pads or tape on the ramp surface to help melt snow and ice before it accumulates.
