E. SECURING THE MASTS
Items needed:
Qty
Description
1 6” Mast Cross Channel, pre-drilled
6 1/2" x 1-1/2”L Grade 8 Hex Head Cap Screw, Washer, and Nuts
1. Raise the mast cross channel into position above the mast beams in the orientation
shown in Figure 24 and bolt into place using the hardware provided. Torque to 99 ft-
lbs.
NOTE: Alignment of the main beams is very important! Check the guide angle
dimension (from bottom to top) against the GA drawing.
2. Recheck the position of the beams and ensure that the beams are not twisted or
turned, and that they are also plumb, parallel, square, and level (beam pairs mounted
in pit floors must be checked closely for level because pit floors may not be poured
level). To maintain proper positioning of the beams – shim under each mast foot
plate as required to fill any gaps between the foot plate and the floor which may have
been created during the plumb-square-level process. Torque bolts on the mast
cross channels to 99 ft-lbs.
NOTE: Beams must be plumb and parallel within 3/8” over the entire
length of beam before proceeding with permanent bracing. The beams
MUST be within this tolerance or the guide wheel assemblies will fail
prematurely.
3. Remove the installation angle (if used).
4. Lag the beams to the floor using four (4) bolts for each mast beam plate – sized to
withstand the pull-out force specified on the GA drawing. Torque to 99 ft-lbs.
