Hello there was a real old cq that had a home made elevator for a rohn 45g tower. It was a one sided elevator with a rotor shelf and trust bearing shelf that road the side of tower on two cables for the track and the center cable that ran around a upper pulley to a crank winch on bottom to raise or lower elevator. Once the elevator reach the top it got ubolted to one side of tower legs with a total of eight ubolts. I have a hazer with a wheel kit and it will not raise a beam over thirty feet of boom length on a 25g. I built a one sided elevator 48 inches long and out of all 3/16 steel. It has a rotor shelf and trust bearing shelf supported to angle iron. I built the top and bottom wider than the tower for leverge on the rideing cables. It will take ubolts on top center and bottom to legs. I have a ten meter seven element beam on a 46 foot boom the beam is light weight 50 pounds. I guess the k factor is high. Once the elevator is ublolted to top i was going to put the trangle plates all around like the hazer and put a brace to the leg incase the ubolts broke. My main concern will the tower hold up the antenna. Thank you Mike kb1qh
