We tried to install racks into ant 26 today and had some problems. The
winch motor sounded like it was straining hard to lift the 350 lb racks.
After the first rack was successfully lifted, we let the motor cool
for awhile. When the second rack was about 2/3 up, the motor completely
died. We let it cool for an hour and it still did not work. (The
breaker was fine.)
Since the rack was stuck hanging in mid-air, we asked for help from the
mechanics. Carl and Phillip got the crane and man-lift and helped us
secure the rack, disconnect the winch cable, and lower the rack back to
the ground with the crane. We will need to repair the winch motor on
Monday before we can continue with the rack installation.
I want to thank Carl and Phillip very much for their help today! We
would have been in a bad situation without these guys help.
