Hi Bill and All,I use a warn XD9000 winch to raise and lower my Tri-ex LM470 Tower. I've got the winch mounted on the raising frame with a pulley at the top of the frame, then a pulley on the tower and the cable feed to it and then back to the raising fixture. (real clear huh?, I can get you a picture if you need it). The cable freewheels out and when the clutch is engaged the cone brake holds the tower in place. With the clutch engaged the tower can be raised and lowered using the winch switch so the brake works all the time. I use a 12v battery to power the winch with no problems in raising or lowering the tower assy.

A winch rated for 'pulling' and a winch rated for 'lifting'. I see Warn and other list a winch having 3500# of 'pulling' capacity. Is this the same as 'lifting' capacity? as always "Please and Thank You". ----------------------------------------------------- "Conclusion": the place where you got tired of thinking ----------------------------------------------------- Bill H. in Chicagoland _______________________________________________ See: http://www.mscomputer.com for "Self Supporting Towers", "Wireless Weather Stations", and lot's more.
