<P class=MsoNormal><FONT color=#1f497d size=2 face=Arial><SPAN style="FONT-FAMILY: 'sans-serif'; COLOR: #1f497d; FONT-SIZE: 11pt">Currently we could lift a Volkswagen if we were going strait up.<SPAN> </SPAN>That’s not the problem though.<SPAN> </SPAN>We want to use the existing poles and cabling to go between the two uprights with a cover.<SPAN> </SPAN>That is, rig something between the uprights that can be lifted using the current cabling by inserting a third cable between them.<SPAN> </SPAN>So instead of just going up we are introducing tension between the two poles and, especially, the two cables.<SPAN> </SPAN></SPAN></FONT></P>
