Wheelchair Lifts offers the solution to a wide variety
of your accessibility problems
Imagine that you
arrive for work one day and your office building is
suspended several feet above the ground. As you look
upward, a feeling of helplessness overwhelms you because
there is not a way for you to enter the building.
Sound far-fetched?
Actually, it's not. This is the real-life dilemma
disable people and people with mobility challenges
confront on a daily basis. Buildings that do not provide
access alternatives for people with disabilities might
just as well be suspended 10 feet above the ground.
The Americans with
Disabilities Act (ADA), signed into law on July 26,
1990, is changing this situation. Effective January 26,
1992, commercial facilities were required by law to be
accessible to people with disabilities. To accomplish
this goal, most buildings in the United States have
several options - vertical platform (wheelchair) lifts,
ramps or elevators. When selecting one of these
alternatives, several factors should be considere3d:
cost, space limitations, aesthetics, upkeep, ease of
use, achieveability, building size and travel distance.
Elevators
are a viable solution in certain applications, such as
heavy-duty, multi-level, interior settings. However, for
shorter vertical rises, whether they are interior or
exterior, they are often too costly and space
prohibitive. Because such settings represent a large
share of the accessibility problems in the real world,
we have limited the following comparison to lifts and
ramps.
A closer look at both
ramps and lifts identifies some key differences.
Lifts Versus Ramps
While ramps may seem to provide a simple,
straightforward solution to any accessibility problem,
upon further analysis it becomes clear that in most
cases the reverse is actually the case.
Whether it is an
interior or an exterior accessibility compliance issue,
ramps like elevators, require extensive space, are
expensive, are hard for disabled people to use and can
have poor aesthetics.
The ADAAG (Americans
with Disabilities Act Accessibility Guidelines) are very
specific about the use of ramps, and federal, state and
local regulations governing the use of ramps abound. For
instance, the angle of a ramp is referred to as the
"slope." The slope is defined by the ratio of the
vertical rise to the horizontal run. Since the slope of
a ramp may not exceed 1:12 in order to comply, for every
inch a ramp rises, it must include at least 12 inches of
run or surface.
In addition, all
landings must have a minimum clear length of 60 inches,
and where a ramp changes direction, the landing must
provide for at least 60 x 60 inches of clearance.
Landings must be provided every 30 feet of ramp run for
resting, at each turn, and at the top of the ramp to
assist in the negotiation of doors and entrances.
Platform lifts, on
the other hand, are better than ramps in nearly all
areas - cost, space efficiency, maintenance and
aesthetics. With a host of design and format options
available, lift systems can be installed in anything
from woodframe enclosures, like small elevators, to
free-standing, attractive, atrium-style enclosures.
A
Well-kept Secret
An often-asked question is, "If wheelchair lifts are so
good, why aren't they more widely known?" There are two
major reasons for this misconception.
First, few people are
aware that platform lifts exist. Secondly, most people
do not understand how lifts can be used and integrated
into a variety of architectural surroundings.
The fact is that
lifts have been successfully solving accessibility
problems in the United States for more than 20 years, in
a wide range of applications. As more and more people
become aware of the important benefits that wheelchairs
lifts deliver in a great many different applications,
the popularity of these versatile and efficient system
will grow accordingly.
Even those who are
aware of wheelchair lifts often incorrectly assume that
ramps would be less expensive. The accompanying graph
(Figure 1) shows the initial costs of a wheelchair lift
as compared to that of a ramp. Initial costs include all
materials and estimated labor of installed lifts and
ramps.
As the graph
demonstrated, the initial costs of lifts are far easier
to control than those of ramps. As the vertical rise
increases, initial ramp costs quickly outpace those for
a wheelchair lift.
Ramp costs are bases
on a standard concrete ramp structure with steel
handrails, built to ADAAG specifications. Lift costs are
based on a "toe-guard telescoping" style wheelchair
lift.
