Note
Action
Secure the
tubular shaft unit
with round-
slings in an overhead crane.
CAUTION
Prevent the slings from sliding!
For example a small plate can be fitted to
the lower attachment hole for the cable
bracket (removed in a previous step). The
plate should be fitted so it points down-
wards and functions as a mechanical stop
for the roundsling.
At the other end of the tubular shaft unit, a
shackle can be fitted if the wrist unit is re-
moved.
