Wheelchair Ramp Design and Construction

A plastic ramp for wheelchair for wheelchairs is an important tool for helping your loved ones live independently in their home. If they are not designed properly, they can be unsafe to use.

ADA regulations require level landings at all changes in direction to avoid compound slopes. They must also provide 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 can comfortably navigate the structure. The ramp's slope shouldn't exceed a 1:12 ratio and the landings have to be level at any change of direction or change in the ramp's surface. The ramp must also be constructed from treated lumber that is more robust and weathers precipitation far better than untreated lumber.

The top and bottom of the ramp should be free of obstructions such as bushes, trees or other structures that can interfere with the safe passage of the ramp's user. The surface of the ramp should also be non-slip and hard. Some municipalities require that the entire ramp be covered with an anti-slip surface.

For the ramp frame, use treated lumber that is at least four inches wide. Create posts to anchor the ramp, ensuring that they are at least eight feet apart and that they extend below the level of the ground. The posts must then be connected with the ramp's railings by using spindles. This kind of connection minimizes the risk of a ramp user falling off the side.

Next, construct the ramp's frame using beams that measure 2 by 4 inches in length and Joists that are at least 16 inches long. The joists must be at least 18 inches above ground and secured with joist hangings, which are nails that grip inside the joists to prevent them from sliding. Attach the ramp for van wheelchair decking with a framing nailer.

Add an upper landing to the doorway to ensure the wheelchair-bound occupants are able to easily maneuver the doorswing. The landing should be 12 to 24 inches on the handle side of out-swinging doors. The landing for doors that are in-swinging should be 58 x 60 inches to accommodate the threshold of the door as well as a wheelchair user who has to reverse through the doorway.

Install a level landing when you change the direction of the ramp, to avoid wheelchairs from having to hit their brakes on corners. A level landing makes it simpler to move a ramp out of the way when needed, so that equipment like lawnmowers can move under it.

Materials

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

Before you purchase any materials or begin construction, make sure that you have the required permits from your local government, and ensure that you adhere to all building codes in your area. Using the wrong materials or construction methods can result in dangerous conditions for wheelchair users. You can find the most up-to-date information regarding construction requirements at your local government's building department office, library or online.

Wood ramps can be the cheapest option for ADA ramp for wheelchair materials. However they require more care. The surface of wood ramps must be regularly treated with a sealer in order to stop warping and rot. 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 expensive, but are durable and long-lasting. They are heavy, which means more labor is required to install ramps and may make it difficult to move the ramp when it is no longer required. Concrete ramps can handle the weight of large power wheelchairs.

Aluminum ramps are lighter than concrete or steel however they possess the same strength and resistance to corrosion. They are also cheaper than iron and steel, making them an excellent option for those with a tight budget. Aluminum is a green choice because it is found in the Earth's crust naturally and can be recycled.

The ramp's upper landing should be in a level area or within 3/8 inches of the threshold of the door to allow wheelchairs with smaller wheels to go across the ramp without getting stuck. Ramps that have a gap greater than this will not meet ADA standards. It is also important to ensure that the ramp is smooth transitioning from the upper landing to the ground surface. The last section of the ramp should have an angled transition to prevent the abrupt stop of wheelchairs as they enter or exit the dwelling.

Installation

A ramp for wheelchairs is an inclined plane that is installed on top of or in lieu of stairs. It allows wheelchair users as well as those who use carts or strollers to access areas that would otherwise be difficult to access.

There are many factors to consider when choosing a ramp for a wheelchair, including size, location, and height. The ramp should be placed as close as possible to the door to prevent unnecessary travel. It should also be placed at an elevation that is easy to navigate by the person who is using it. It should be securely anchored to the floor and clear of obstructions, such as car parks, shrubs or other obstacles.

ADA regulations stipulate that ramps must have handrails on either side. The rails must be at least 36 inches apart and have an edging surface that is smooth or rounded. 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 constructed with switchbacks or an L-shaped layout.

The length of a ramp depends on the incline, however there are a few standard ramp types that can be used in most situations. For instance the threshold ramp is right on the edge of a curb or at the threshold of a doorway while portable ramps can be moved from one location to another and are available in many different sizes. There are also aluminum ramps with modular design that can be assembled on-site. These ramps are commonly employed in public or commercial areas and are usually longer.

If you are considering a permanent ramp, make sure to check with the building department of your city to determine if you require a permit. It is also advisable to speak with a mobility specialist about the type of ramp that will work best for your needs and space. In some cases installing an all-weather ramp can boost the value of your home.

Maintenance

It is essential to ensure that your wheelchair ramp is well maintained, especially if will be using it often. You'll need to perform regular inspections, and correct any structural issues as they arise. This will ensure that the ramp complies all ADA requirements, and is safe for the users.

Wooden ramps require regular cleaning to get rid of dirt and debris that could block access. Cleanliness of the ramp will also stop moisture from accumulating beneath the surface and leading to decay. The wood preservatives or stains can only be effective if the ramp has been thoroughly cleaned prior to application.

Wheelchair ramps are more difficult to maintain than other ramps because they are more likely wear and tear. It is crucial to have the proper tools. To ensure that all fixings are secure and tight you'll require an appropriate set of screwdrivers and gauge spanners. You should also regularly inspect the handrails for signs damage or corrosion. As time passes, and with repeated use, it's possible for some of the fittings or bolts that hold the handrails to become loose. This could pose an unsafe situation for anyone using the ramp.

Another crucial aspect is to ensure that the surface of the ramp is grippy, especially in winter when conditions can be challenging. You'll need to remove any leaves, dirt and other debris that can obstruct the surface and cause slippage. You'll also want to apply an ice melt that is non-corrosive on the ramp surface to prevent slips and injuries.

If you're planning to use your ramp during winter, consider investing in traction wheels or "snow tires" for your electric wheelchair car ramp. They're specially designed to provide better tracking on uneven surfaces and snow which is why they'll be more effective than standard wheelchair tires at keeping you on the ramp. You can also make use of heating pads or heating tape to melt the ice and snow on the ramp before it builds up.
