SPLICED BEAMS (when used)
1. Set the upper mast on its respective lower mast (plates & beams are marked) in the
orientation shown on Figure 24, taking necessary precautions not to bend or damage
transition plates.
2. Verify that all four beams are true, straight, and plumb within 1/8” over any 10 foot
span and not to exceed 3/8” over the entire length of the beam.
NOTE: This tolerance may not be exceeded or immediate & permanent damage to
the hardened wheel guide wheels will occur. (Shim material by installer).
3. Once all beams are verified to be straight & plumb as specified as above,
permanently weld the upper & lower mast assemblies together as shown. Weld
distortion to the beams must be minimized to hold the required tolerance to beam
straightness.
NOTE: Care should be exercised not to distort the masts from welding,
and alignment is critical. Grind the guide beam to provide a smooth
surface for the guide wheels and rollers.
NOTE: Beams must be plumb and parallel within 3/8” overall before
proceeding with permanent bracing. The beams MUST be within this
tolerance or the guide wheel assemblies will fail prematurely.
