Bolt Tightening
Tightening of the base plate
mounting bolts directly affects
vertical arm alignment and base
plate warpage. Tighten inside
mounting bolts first, then tighten
outside mounting bolts. Measure
alignment of towers and vertical
arms while tightening. See Figure
M.
Note:
Towers must be aligned
and parallel, with handrails se-
curely nested in the guided stow
blocks. See Photos A and B.
Mounting Bolt Torque Speci-
fications:
28 to 31 foot
pounds. Adjustment to mount-
ing bolt torque may be required
to achieve proper alignment.
Design Lifting Capacity:
See
page 22 for details.
