Wheelchair Ramp Design and Construction

A wheelchair ramp is a vital tool for helping a loved one to live at home independently. If not designed correctly they can be dangerous to use.

ADA regulations require that landings be level at any change in direction, so as to avoid compound slopes. They also must provide a surface that is gripping for wheelchair users.

Design

The ramp's design should be in line with the Americans with Disabilities Act standards to allow wheelchairs to navigate the structure easily. For instance, the ramp's slope should not exceed the ratio 1:12 and must have landings that are level upon any change in direction or change in the ramp's surface. It also must be constructed of treated lumber, which is more durable and weathers precipitation far better than untreated lumber.

The sides and top of the ramp should be free of obstacles like bushes, trees or other structures that could hinder the safe passage of the ramp's user. In addition, the surface of the ramp must be smooth and non-slip. 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 four inches wide. Make posts to support the ramp, ensuring that they are at least eight feet apart and that they extend above the ground level. Spindles are the best way to connect the posts to the ramp's railings. This type of connection reduces the possibility of a ramp user falling off the side.

Next, construct the frame of the ramp using beams that measure 2 by 4 inches in size, and joists that are at minimum 16 inches long. The joists should be placed at minimum 18 inches above the ground and secured using hangings for joists which are nails that fit inside the joists to prevent them from sliding. Attach the ramp decking with framing nails.

Add an upper landing near the doorway to enable people with disabilities to navigate the doorswing without difficulty. The landing should be 12 to 24 inches on the handle side of doors that out-swing. For doors that swing in the landing should be at minimum 58 by 60 inches to allow for the threshold and a person in wheelchair who must walk backwards through the doorway.

Install a level landing when you change the direction of the ramp to stop wheelchairs from having to hit their brakes into corners. A level landing makes it simpler to move a ramp out of the path if needed, so that lawnmowers and other equipment can move under it.

Materials

Aluminium, wood, or concrete can be used to construct ramps for wheelchairs. A professional electric wheel chair ramp installer will help you choose the best option for your office or home. It is important to consider your budget and needs when choosing the materials for the ramp. The ramp should be simple to maintain and must be safe to use. Some cities require that the ramp be laid out with a non-slip, non-slip surface.

Make sure to inquire with your local government for permits before you begin building or purchasing materials. Also, make sure to adhere to all local building codes. Making use of the incorrect materials or methods of construction could result in hazardous conditions for wheelchair users. You can get the most up-to-date information regarding construction requirements at your local building department office, library or online.

Wood ramps are often the least expensive of ADA ramp materials, but they require more care than other alternatives. The surface of wood ramps must be regularly treated with a sealer to avoid rot and warping. Wood can splinter, which can be especially hazardous for those who are in wheelchairs. Wood ramps may also require additional support to keep the structure standing and steady.

Concrete ramps can be costly however they are durable and long lasting. They are also heavy, which demands more work to construct and can make moving the ramp once it's no longer needed difficult. Concrete ramps are able to withstand 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 more affordable than iron or steel, which makes them an excellent choice for those with a tight budget. Aluminum is also eco-friendly because it is found naturally in the earth's crust and can be recycled.

The upper landing of the ramp should be level or within 3/8 inch of the door threshold in order to allow the front wheels of smaller wheelchairs to cross it without becoming stuck. Ramps with a gap larger than this won't meet ADA standards. It is also important to make sure that the ramp transitions smoothly between the upper landing and the ground. The final section of the ramp must have a a beveled transition to avoid an abrupt stop for wheelchairs when they enter or leave the dwelling.

Installation

A wheelchair ramp is a plane inclined that can be installed as an alternative to or in addition to stairs. It allows wheelchair users, as well as people who use carts or strollers to get into areas that would otherwise be difficult to access.

When choosing a plastic wheelchair ramp access ramp, there are many aspects to take into consideration, including the location, height and cost. A ramp should be placed as close to the door as it is possible to prevent unnecessary transportation. It should be located at a height that the person using it can easily walk on it. It should also be properly anchored to the ground and free of obstructions, like trees or parked cars.

ADA regulations require that ramps must have handrails either side. The rails should be at least 36" apart and have smooth or rounded gripping surface. They should also be connected to the edge of the ramp and extend 12 inches beyond the ramp. If a ramp is equipped with switchesbacks or an L-shaped layout handrails should be a continuous length between the ramp's edges.

The length of a ramp depends on the incline, but there are several standard ramps that can be used in all situations. For instance the bridge threshold ramp for wheelchair ramp is directly on the lip of a curb or the threshold of a doorway, while portable aluminum folding wheelchair ramps ramps can be moved from one location to another and come in a variety of sizes. Modular aluminum ramps can also be assembled on-site. They are typically used in public or commercial areas and are typically longer than the threshold and ramps that are portable wheelchair ramp for Van.

If you're thinking of a permanent ramp, make sure to check with your city's building department to determine if you'll need an approval. It is also advisable to speak with an expert in mobility to determine the type of ramp that is best for your needs and the space. In some cases installing permanent ramps could increase the value of your house.

Maintenance

It's important to make sure your ramp for wheelchairs is maintained, especially if you are going to use it often. You'll need to perform regular inspections, and correct any structural issues as they occur. This will help ensure that the ramp is in compliance with all ADA requirements and is safe for all users.

Wooden ramps require regular cleaning to get rid of dirt and debris that can obstruct access. Cleaning the ramp regularly will also prevent moisture from accumulating under the surface and causing the onset of rot. Preservatives and stains for wood only work when the ramp has been thoroughly cleaned prior to applying.

Wheelchair ramps are more difficult to maintain than other ramps due to the fact that they are more prone to wear and tear. The most important thing to do is ensure that you have the right tools to complete the task. A set of gauge spanners and screwdrivers is essential for making sure all fixings are tight and secure. Also, you should regularly check the handrails for signs of damage or corrosion. Over time, and with repeated usage, it's possible for the fittings or bolts that hold the handrails to become loose. This can be an unsafe situation for anyone who uses the ramp.

Another important factor is ensuring the surface of the ramp has enough grip, especially in winter, when conditions can be a challenge. You'll need to sweep away any dirt, leaves or other debris that could obstruct and cause slippage. You'll also want to apply an ice melt that's non-corrosive to the ramp surface to avoid slips and injuries.

You should consider purchasing "snow tires" or traction wheels for your wheelchair van ramp if are planning to use it for the duration of the winter. These are specifically designed to aid in tracking on snow and uneven surfaces, so they'll be more effective than standard wheelchair tires in helping you stay on the ramp. Alternately, you can put heating pads or tape on the ramp's surface to melt ice and snow before it accumulates.
