Commercial accessibility lifts, and their limitations under the B-355 code

by Andrew @ Uppercut

Commercial accessibility lifts are a cost  effective solution when it comes to making public buildings accessible. Vertical platform lifts or VPL’s can eliminate barriers for wheelchair users or those faced with mobility issues. Their relatively small footprint and minimal contractual requirement make them ideal for existing public buildings where accessibility is a concern. They do however have their limitations under the B-355 code, which they are inspected.

The first consideration is platform size. Public accessibility lifts are mandated to have a platform that is no greater the 21 square feet. A typical “large” wheelchair lift would have a 48″x 60″platform. This size of platform is big enough to accommodate a wheelchair user doing a 90-degree turn. A more common size would be in the range of 34″ x 54″ where the user enters and exits on the same side, or travels through the platform and exits on the opposite side.

Next, we must look at the  travel restrictions that are imposed within the code. Enclosed  B-355 accessibility lifts can travel no more than 7000mm or 23.1 feet. Unenclosed wheelchair lifts can travel up to 2500mm or 98.25″. Enclosed units will require a hoistway constructed around the device with a door at the lower landings and the minimum of  a gate at the uppermost landing. Unenclosed units travelling more than 500mm (19.65″) will require a gate or a door at the upper landing. It should be noted that any lift penetrating a floor will be required to be an enclosed vertical platform lift needing a hoist-way constructed.

The weight capacity  of wheelchair accessibility lifts varies from manufacturer to manufacturer, but most unenclosed vertical platform lifts have a capacity of either 550lbs or 750lbs. Enclosed units usually have a capacity  somewhere between 750lbs – 1400lbs.

Perhaps the biggest drawback of public accessibility lifts is the requirement for them to operate using constant pressure. This simply means you must hold the button for the device to operate. This is partially due to the fact the lift platform has no gate or sliding elevator door.

As universal accessibility for all members of society  is now considered the norm , the popularity of these barrier free lifts has increased. You can find barrier-free accessibility lifts  in most schools, community centres and places of worship.

Commercial Accessibility Lifts – Understanding the Code and Approval Procedure

Commercial accessibility lifts are governed by the B-355 code. If a lift is being installed in a public application make sure that your lift provider specifies that the product is B-355 code compliant. All public lifts are required to be registered with the Alberta Elevating Devices Amusement Rides Safety Association (AEDARSA). After a lift is registered, and the engineered stamped drawings are reviewed, AEDARSA then issues a Certificate of Construction. Now your lift provider may proceed with the installation of your elevating device. After the installation is complete AEDARSA will need to be booked  for the initial inspection.

 

 

 

 

To recap the procedure is:

  1. Generate engineered drawings (lift provider)
  2. Registration of the lift with AEDARSA (lift provider)
  3. Review of the drawings  (AEDARSA)
  4. Issue certificate of construction (AEDARSA)
  5. Installation (lift provider)
  6. Inspection (AEDARSA)

Now that we understand the procedure it is important to know some of the code restrictions as they pertain to vertical platform lifts.

Travel

Enclosed B355 devices  are limited to a total travel of 7000mm or about 23 feet, while unenclosed lifts may  travel up to 2500mm or 98.25 inches. It`s important to note that unenclosed platforms may not penetrate a floor. Travel is defined as the floor to floor measurement. This typically limits accessibility lifts to 3 story buildings.

Platform size

The platform or lift car is limited to 21 square feet. If the platform is configured in a straight through application a 34x 54 inch (12.75 square foot) car size is often acceptable. If the site dictates adjacent access or a 90 degree turn, we recommend a larger platform to make the turn easier for the wheelchair user.

Constant Pressure

This is one of the major restrictions of the code. Public accessibility lifts are required to operate using constant pressure. This means you must hold the button in order for the lift to operate.

Capacity

Depending on the manufacturer, your vertical platform lift may have a 550, 750, 800, or 1000lb capacity. Some manufacturers make lifts than can accommodate up to  1400lb, but it should be questioned as to why you want this higher capacity, as there are limitations on platform size.  They may be  designed to accommodate an individual user in a wheelchair, or allow for an attendant as well. Your lift provider should make sure the platform size and capacity meet your specific needs while still satisfying code.

Hoist-way Construction

This work would typically be completed by a third party (not the lift supplier). Each lift will have specific criteria regarding the contractual requirements but it can be broken down into Enclosed and Unenclosed applications. The following documents explain the contractual requirements for each elevating device.
