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.

Advantages of (Machine Room-less) MRL Elevators

by Andrew @ Uppercut

This article is not referring to passenger elevators and is intended to discuss the advantages of MRL Elevators in a residential or commercial accessibility lift setting. A machine room-less elevator or an MRL Elevator is a device that typically houses the drive mechanism at the top of the hoistway. By doing this the need for a machine room is eliminated, as the entire device is contained within the elevator footprint.MRL elevator

Units that require a machine room( like most hydraulic drives) will also require the electrical and hydraulic hoses to run through a wall from the machine room to the elevator hoistway. In cases where the machine room is not adjacent to the elevator, a remote machine room will be required.  This can be costly and create logistical problems with the running of hydraulic hose through the floor, ceiling or in the walls. It also poses several maintenance concerns; What if a hose ran through a ceiling for instance and it starts to leak? Will it be possible to do a scheduled hose replacement? What type of ongoing costs should you expect in this application? This is a definite advantage of an MRL, having the entire elevator in one contained space.

The second advantage is quite simple; with an MRL elevator, you do not have to allocate the additional space to house the drive mechanism. Depending on the drive system and whether the installation is residential or commercial (B-355),  a machine room could require anywhere from 12  to 20 square feet.  This is space that could be used for storage, a larger elevator car, or a revenue opportunity (like a couple of extra tables in a restaurant).

Finally look at all the costs associated with constructing that machine room. If you think about it,  its equivalent to the cost of half the elevator hoistway  (2 stop). On top of the basic room construction, you will need to provide lighting, possible drains, sump pumps or oil separators, additional sprinkler/smoke detectors, and an additional door (fire rated in a public application).  These costs can add up quickly, and should be considered when calculating the overall cost of the elevator.

To recap MRL Elevator units will:

  • Save you money when it comes to maintenance
  • Require less space
  • Reduce the initial cost of construction

Comparing Porch Lift Features

by Andrew @ Uppercut

When choosing a porch lift supplier it is important to do a detailed  comparison to ensure that the specifications of each product and company match.

Areas where discrepancies can occur include:

  • Standard platform size – You should note that not all manufactures make a standard platform the will accommodate a larger wheelchair or scooter. This is sometimes a costly upgrade so it needs to be discussed up front.

 

  •  Finish – Some lifts are painted while others come with a durable powder coated finish. Remember to ask about the costs associated with powder coating your lift.

 

  • Capacity – 750lbs seems to be the industry standard but there are still some 550lb capacity lifts on the market

 

  • Cold weather operation – Some porch lifts require the addition of an outdoor package. If your lift is exposed to the elements make sure it has this provision or a feature like a “Zero load start”  to ensure your lift operates in cold temperatures

 

  • Safety features – Ask about the safety record of the lift. Does it have a fall arrest system, platform kick plate, and easy to access manual lowering device?

 

  • Where you buy – This is hard to quantify at the time of purchase, but it must be considered when making your decision. An indication of the type of company you are dealing with may be given by the sales person. Did they return your call promptly? Did they offer to come out and meet with you, or did they just send a quote? Were they prepared with brochures, and was the quote they provided comprehensive? How many people do they employ, and do they have the resources to service your porch lift if needed?
