Wheelchair Ramp Design and Construction
A ramp for wheelchairs is a crucial tool in helping your loved ones live at home in a way that is comfortable for them. If they are not designed properly they could be unsafe to use.
ADA regulations require that landings be level at any shift in direction to avoid compound slopes. They also must provide a grippy MONZANA® 2X Auffahrrampe – 400 kg Capacity Perforated Surface 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 a ratio of 1:12 and must have landings that are level upon any direction change or change in the ramp’s surface. It must also be constructed from treated lumber that is more durable than untreated lumber and can withstand mymobilityscooters the effects of rain better.
The sides and top of the ramp should be free of obstacles such as bushes, trees or other structures that may hinder the safe passage of the ramp’s user. The surface of the ramp must be non-slip and hard. Some municipalities require an anti-slip surface running along the entire length of the ramp.
Use treated lumber at minimum 4 inches in width for the ramp frame. Make posts to support the ramp, ensuring they are at least eight feet apart, and that they extend above the ground level. The posts should be connected with the ramp’s railings by using spindles. This kind of connection is preferred because it reduces the risk of the ramp operator falling off the side of the ramp.
Then, build the frame for the ramp using joists that are at most 16 inches long and 2 by 4 inch beams. The joists should be placed at least 18 inches above the ground and secured using hangings for joists, which are nails that grip within the joists, preventing them from sliding. Attach the ramp decking using a framing nailer.
Install an upper landing on the doorway to ensure wheelchair users can easily navigate the doorswing. This landing should be large enough to give at least 12-24 inches of “elbow room” on the handle side of out-swing doors. 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 a wheelchair who needs to move backwards through the doorway.
Install a level landing when changing the direction of the ramp to stop wheelchairs from having their brakes on corners. A level landing allows you to move the ramp out of the way when needed, so that lawnmowers or other equipment can pass underneath it.
Materials
Aluminium, concrete, or wood can be used to build ramps for wheelchairs. A professional ramp installer will help you select the most suitable option for your office or home. It is essential to take into consideration your individual needs and budget when selecting the materials for the ramp. The ramp should be easy to maintain and should be safe for use. Some cities require that the ramp be paved with a non-slip surface.
Before you purchase any building materials or begin construction, make sure you have the required permits from your local authority and that you comply with all building codes within your area. Incorrect construction materials or techniques can create dangerous conditions for wheelchair users. You can find the most current information regarding construction requirements at the building department of your local government office or library, or on the internet.
Wood ramps are often the least expensive choice of ADA ramp materials, but they require more care than other options. The wood ramp’s surface must be regularly treated with a sealer in order to stop rot and warping. Wood can split and be hazardous for those using wheelchairs. Wood ramps can also need additional support in order to keep the structure in place.
Concrete ramps are extremely durable and long-lasting However, they can be expensive. They are also heavy, which demands more work to construct and can make moving the ramp when it’s no longer needed difficult. Concrete ramps can withstand the weight of large power wheelchairs.
Aluminum ramps weigh less than steel or concrete however they possess the same strength and resistance to corrosion. They are also more affordable than iron and steel which makes them a great alternative for those on budgets. Aluminum is a green choice because 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, allowing wheelchairs with smaller wheels to go over the ramp without becoming stuck. Ramps that have a gap higher than this conform to ADA standards. It is also important to ensure that the ramp moves smoothly between the upper landing and the ground surface. The last section of the ramp must have a beveled transitions to avoid an abrupt stop for wheelchairs when they enter or exit the dwelling.
Installation
A ramp for wheelchairs is an inclined plane that is installed on top of or instead of stairs. It lets wheelchair users and those who use strollers or carts to get around areas that are otherwise difficult to access, such as the front door or a set up of steep steps.
When choosing a wheelchair access ramp, there are numerous factors to consider, including the location, height, and price. The ramp should be placed close to the door to prevent unnecessary travel. It should be set at a level that the person using it can easily navigate. It should be securely anchored to the floor and free of obstructions, such as car parks, shrubs or other obstacles.
ADA regulations stipulate that ramps must have handrails either side. The rails must 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 it. If a ramp is equipped with switchbacks or an L-shaped layout handrails should be a continuous length between the ramp’s edges.
The length of a ramp varies on the slope, however there are several common ramps that can be used in all situations. For instance the threshold ramp is placed right on the edge of a curb or at the threshold of a doorway while portable ramps can be moved from one spot to another and come in a variety of sizes. There are also Lightweight Aluminum Mobility Ramp – 300kg Capacity ramps with modular design that can be built on-site. These ramps are commonly used in commercial or public areas and are typically longer.
Check with your city’s construction department to determine if a permit is required for an ongoing ramp. You should also speak to an expert in mobility about the kind of ramp that is best for your needs and the space. In some instances the installation of an all-weather ramp can increase the resale value of your home.
Maintenance
It’s crucial to ensure your wheelchair ramp is well maintained, particularly if you will be using it frequently. You’ll need to perform regular inspections, and fix any structural issues that arise. This will ensure that the ramp complies all ADA requirements and is safe for users.
Wooden ramps require regular cleaning to remove debris and dirt 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 effectively if the ramp is completely clean before application.
Wheelchair ramps are more challenging to maintain than other kinds of ramps, since they are more prone to wear and tear. It is important to have the proper tools. A set of gauge spanners as well as screwdrivers is essential for making sure all fixings are tight and secure. Also, you should regularly check the handrails for signs damage or corrosion. Over time, and with repeated usage, it’s possible for the bolts or fittings the handrails to become loose. This could pose a safety concern for anyone using the ramp.
Another important factor is ensuring the ramp’s surface has enough grip, especially in winter, when conditions can be difficult. You’ll need to remove any leaves, dirt and other debris that could block the surface and cause slippage. You’ll also want to apply an ice melt that is non-corrosive to the ramp surface to prevent injuries and slipping.
If you’re planning on using your ramp during winter, consider investing in traction wheels or “snow tires” for your wheelchair. These wheels are designed to be more efficient on snowy surfaces and uneven surfaces. They can help you remain on your ramp more effectively than regular wheelchair tires. Alternately, you can put heating pads or tape along the ramp’s surface to help melt snow and ice before it gets accumulated.
