<DIV>Hey guys,</DIV>
<DIV> </DIV>
<DIV>I am wanting to build a gantry lift in my shop so I can put my sub on the
trailer and take it back off the trailer without having to pay to rent a
telehandler. It would need to hold the sub (4500 lbs) plus a little extra. I
was thinking of building it out of I beams. I know nothing about structural
design with I beams but I believe it should be pretty easy. The gantry lift
would be 9' tall and 8' wide. What size I beams should I use?</DIV>
<DIV> </DIV>
<DIV>Also what is the best kind of winch or block and tackle device to use
that is inexpensive?</DIV>
<DIV> </DIV>
<DIV>Thanks for the help,</DIV>
