I used to install this stuff, but I don't know pricing and haven't
seen much of a second-hand market for parts or repairable broken
Personally I don't have business insurance and won't homebrew or
repair any medical or handicapped hardware. The government will buy it
for you if you really need it.
Acuride is a big manufacturer of drawer slides, have you checked their
Or you might try McMaster Carr for one stop shopping http://www.mcmaster.com/
they have quite a range from much too small to much too expensive,
with luck you will find something in between. I hope you don't need
their bigge$t ones, though with a motorized wheelchair and passenger,
I don't know. Has anyone really ever spent $1616 for a pair of drawer
slides? sure, with a 49" extension and a 820lb capacity they are
impressive, but $1616!
Might have look at these folks. I have always had good luck from them and A+
cutomer satisfaction. No affilitaion other than satisfied customer. They say
not for human support but look at what they are designed for. Looks like you
could double them if necessary. That what you are paying ........the
statement it is intended for medical use and not for some other use. Good
luck and you might tell customer service about your dilema and ask if they
know of a vender in the line you are looking for.
If the link does not work search for heavy duty slides.
One problem - if you tell them that the slides are for use in
building a wheelchair lift, they will not sell them to you - the much
higher added injury and liability insurance costs for components used
in a personnel lifting device and/or medical device aren't factored
into "drawer slides". And if you read the fine print on the
instructions there's more than likely words to that effect.
If you don't tell, you accept all the liability. For a one-off lift
you build to solve a mobility problem for a family member, this is not
a problem. If you plan to produce these lifts for resale, it can be a
huge problem. You'll have 100 units pre-sold at a pre-set price, and
your supplier either cuts you off cold or the price of a key component
For resale, contact the manufacturer and work it all out first.
Example: You can buy all sorts of cable winches and overhead powered
hoists and trolleys, including inexpensive import units at Harbor
Freight - and they all say "Not for overhead lifting over people, or
for lifting people." If they know you are building an elevator with
their hoist (and they have any brains at all) they won't sell.
If you want a unit that is rated and sold to lift people or over
people, the only place I know of to get one in the USA is from CM
Hoist (Columbus McKinnon), and you pay a lot more. And more for the
"Overhead Lifting" rated alloy chain and rigging gear.
