Hello tower experts, I'm in the process of refurbishing an old EZ-Way crank-up and looking to replace some lift cable sheaves which have excessive wear in the ID of the groves. The current 3" OD meta
No experience with wire rope on nylon, but you might consider the UV degradation of nylon as a drawback, particularly since one segment of the sheave is exposed for long periods. (assuming you leave
I have a old EZ-way tower (RBX-50) and NO WAY would I use any kind of plastic/nylon pulley on that lift system!!! Sure, the nylon might carry the load when new, but nylon eventually will get brittle
I have seen Nylon pulleys with wire used on small sailboats with low stress on the pulley but never in a high stress application. I too would be concerned with UV degradation with lengthy exposure. A
I looked at those a few months ago and I would not use them even if they do meet requirements. I agree with N0TT, they would probably not last long in the WX. 73 Buddy WB4M I'm in the process of refu

Hi Tony - Some time ago I tracked a 60 foot pole. It worked fine but then I "inherited" a tower. I haven't seen the track/ "carriage" you reference but it sounds like a good starting point. However,

Hi Tony, If you haven't already fashioned a rotator plate to ride the track, IIX makes one for pole mounting called the RM-2 Pole/Building Mount - http://www.w9iix.com/mounts.htm 73, Jon Pearl - W4AB

The problem I had with these was that the pulley wheel edges wore/rusted/pitted away. Normally the shape is concave to keep the wire rope from jumping the wheel and getting the stuck between the whee
And one of the interesting things is that Oilite bearings actually hold up under static shock loads (think wind loading on a tower cable that doesn't move that often) MUCH MUCH better than ball or ro
There ARE answers to oddball problems like these, sometime worth it, sometimes not. What you need to do is find a job shop machinist. You bring him the old pulley, explain the problem, and say "What
Here's a follow-up for those that might be reading this thread. Roger raises some good issues (repeated below). First of all, I don't intend to use nylon sheaves, but wanted to see if anyone had expe
