I second what Joe proffers, I lost [dropped] my mast last year about
10-12 feet weighing near 350-400 pounds with all included, and geez oh
Pete, a small bottle jack was all i could get to fit in the
circumstances, and to get all the mast back up took lot of work to at
my guess was about 5" of lift from the jack per effort then reset the
clamps and start the whole sequence all over till it was finally raised
back up and in place... watching paint dry would have been more fun..

Tony,
I would not trust that small bolt to hold up the mast while working under it
(on the rotor) I use a muffler type U bolt above the thrust bearing to
secure the mast.
Good luck

Subject: [TowerTalk] Rotator Swap U.S. Tower Crank-Up
All:
Not sure if this is the proper procedure, but the last time I replaced a
Yaesu rotator on my U.S. Tower heavy-duty crank-up, I used the bolt that's
built into the tower to hold the mast in place to kept it from from falling.
It seemed to hold 100lbs of antennas just fine, but was wondering if I
should clamp the mast at the top above the bearing for a bit of insurance.
Tony
