[TowerTalk] HDX 555 Motor Drive BEaring

[Mac]

Steve is also very correct here,  its all about cable management and i 
do a very poor job of it to the point that i am about to rework my tower 
and base scheme and am exploring those loop holders things that 
metalwerks makes i think it is, using those mite well instill some 
higher level of cable management confidence and let my thinking roam to 
remote operation possibilities...

Yes i know mite  i fondly remember my first Mite teletype machine and 
when i use mite it is just a fond memory for the machine i carry..

If not in use for an extended time, why not crank it down?  I have a wind-gauge relay device that actuates my tower to bring it down automatically when the wind exceeds 30 mph.

With proper cable management there is no reason why the cables should get “snagged", tangled or stuck.  If your cables are getting stuck, you need to redesign the management.
> When the tower was at my home QTH I raised and lowered the tower every time I used it. It was always kept cranked down.  I used it so much I had significant wear on the sheaves. (some have been replaced twice)  I talked to US tower directly about running the tower so much.  The answer from the company was “these towers are made to go up and down. We have some installed at skeet shooting ranges were they go up-and-down repeatedly everyday”

> Obviously things can break, but regular inspection and maintenance can mitigate some of that. BTW…if the limit switches fail, the tower will not come crashing down.  What will happen, is that the belt will slip and burn out. (had that happen once)

> If running your crank-up tower is too “risky” for you to do when not standing beside it, I respect that.  The purpose of this response is to point out that my tower has probably gone up and down over 1,000 times over the 18 years I have owned it and I did not stand there and watch it every time.

>> That all said, im the guy who is always late getting it lowered and damn that typically brings some excitement with it and the static build up on my elements when that drains off..  But even then i will not be a remote guy, my best effort is i have made up a hand held pendant up / down controller with a 100' cable, so i can roam around and check from various positions and sight lines.

>> Also in my case the i really like seeing the limit switches and the traveling actuator moving toward or away from the actuator or limit switch [HDX-589 model] so overall im trying to say for me and my situation and safety, ill still go out in the rain, gusty winds and take care of business.
>>
>> And let me add,  at the outset i never gave much thought to the PULL DOWN feature, but the way and how my location is set up here, i truly have seen times when the "up lift" was such a force it took the mechanical effort to bring the tower down, usually of short duration, but it does occur in gusty winds.
