In my American Automotive Equipment Lift, there are twin hydraulic
cylinders, one in each post, the cables are an alignment device to keep
them in sync. They don't actually lift the car, just prevent one
cylinder from going up faster than the other. Also, the safety locks
are mechanical. They click into place as twin wedges on each post as
you go up, and you pull a cable release on each side to lower it.
Pretty simple and not subject to much failure , like losing air
pressure. It also has a leg lock. When it's totally down, each leg can
be moved under the car at will, but when it lifts up 1/2" the locking
device holds them from moving. I have had cars somewhat twisted and
that left 1 leg free to be moved totally out from under the car,
leaving it held up on 3 legs only. Found that out while under the car
and putting a tool on the leg, it swung away.
The lift also has a 1/8" cable which goes across the top a few inches
down from the crossover. This cable shuts off the pump if nudged,
preventing you from putting a tall vehicle too high and crunching it.
That's 3 safety devices, and it's parts are massive, with very nice
looking welds. I thought 9,000# was more than I needed, but for several
hundred more you can get 12K.
As to a 4 post lift, it depends on if you want a parking garage with doing some work once in a while or you need to do a lot of car work. A 4 post has (Or should) drip trays to protect the car underneath. To work on anything, you have to jack it up off the ramps and work around the ramps. I've found that no matter what you want to do, the damn ramp is in the way. Having done hundreds of alignments on ramp lifts, i know of where I speak! So be sure of your needs. You can leave a car up on a twin post as you let it down on the latches anytime you use it, but the car under it can be dripped on. This old guy ain't rolling around (let alone getting up from) a creeper anymore! Ray On Oct 26, 2006, at 1:58 AM, William Huff wrote: Same question, different company, ASE Deals offers a 9000 lb. Bend-Pak, made in the USA, commercial grade with free shipping and it has air operated safety devices if a cable should part. Same basic price. Anyone know about Bend-Pak?http://www.asedeals.com/garage_lift.html Thanks Again. Hi,Has anyone used or had experience with Affordable Automotive Equipment? They are in Orlando and I was thinking of purchasing one of their 4 post lifts, either the Pro Park 9 Plus or the Pro Park 7. I think they deal in Direct-Lift products.http://www.affordableautomotiveequip.net/ Thanks, Bill Huff ************************************************************* To unsubscribe or set your subscription options, please go to http://lists.psu.edu/cgi-bin/wa?SUBED1=l-forwardlook&A=1 ************************************************************* To unsubscribe or set your subscription options, please go to http://lists.psu.edu/cgi-bin/wa?SUBED1=l-forwardlook&A=1
