E. JOINING & SECURING THE MASTS (Reference Figure 25)
Items needed:
Qty
Description
2 Mast Cross Channels (6”)
varies 1/2" x 2”, Grade 8 Hex Head Cap Screws, Washers, and Nuts
1. Join the Left mast pair assembly to the Right mast pair assembly by installing the
front and back mast cross channels using the 1/2" x 2” lg. bolts, lock washers, and
nuts provided. These channels are stamped LB, RB (left back, right back) and LF,
RF (left front, right front) for proper orientation. Snug down the bolts so as to permit
later adjustment. For placement, refer to Figure 25.
NOTE: Alignment of the main beams is very important! Check the guide
angle dimension (from bottom to top) against those shown in the job-specific
General Arrangement / Record 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 two (2) installation angles.
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. Hand snug these anchor
bolts only, do not tighten at this time.
