To verify the specs on my unit, I measured the single line speed of the cable and clocked it at 9" per second. With pulley reduction, the speed of lift is 2.25" per second. <br> <br> It was a fast guess on my part when I was standing there in the store looking at pulleys. Now I might want to use 6:1 reduction if I had my druthers. But lacking that, I just give it short bursts at the critical moments and it works fine.<br> <br> Tom Cole<br> <br> Robin Stevens wrote:<br> <blockquote type="cite" cite="mid41B8BB83.000001.02452@ROBINSHPTOWER"> <meta http-equiv="Content-Type" content="text/html; "> <meta content="IncrediMail 1.0" name="GENERATOR">  <table id="INCREDIMAINTABLE" cellspacing="0" cellpadding="2" width="100%" border="0"> <tbody> <tr> <td id="INCREDITEXTREGION" style="font-size: 12pt; cursor: auto; font-family: Arial;" width="100%"> <div> I use one of these lifts for another application, and find that they are fast!!

Oops, scrap the nylon thing - I see</div> <div>now they are polyester (I'm looking at one). They are 1-inch wide and</div> <div>4-feet long. They have a vertical capacity of 1,600 lbs. They have big</div> <div>loops at each end. I purchased them at Wholesale Tool</div> <div><a href="http://www.wttool.com/">http://www.wttool.com/</a> .</div> <div> </div> <div>Originally, I used three of these straps only and hooked them into my</div> <div>ceiling-mounted chain-fall. I would have to manually try to adjust their</div> <div>positions to get an even lift - very less than optimal. After picking up</div> <div>some ideas from this list, I am now using two adjustable straps between</div> <div>the polyester strap on the plate and the hook of the chain-fall (I use</div> <div>the adjustable thing on the two front straps and simply run the rear</div> <div>strap full-length directly from the plate to the chain-fall hook - no</div> <div>adjustment). The adjustable straps I am using are rather light-duty (I</div> <div>seem to recall a breaking strength of around 400 lbs. - arguably</div> <div>somewhat marginal strength) and do not have a ratchet, but rather a</div> <div>simply thumb-controlled hold-clamp-apparatus (it's actually a thingee) -</div> <div>it has never slipped (yeah, I know what you are thinking - me too!).</div> <div>Very quick to adjust and easily get a nice even lift. When I see</div> <div>something similar, but with higher breaking strength, in a tool store, I</div> <div>will pick those up and switch to something with a greater weight rating.</div> <div> </div> <div>If anyone wishes for a picture, I would be happy to take one and send it</div> <div>your way.
