SPLICED BEAMS (when used)
1. Set the upper mast on its respective lower mast (plates & beams are marked) in the
orientation shown on Figure 23, taking necessary precautions not to bend or damage
transition plates.
2. Verify that all four beams are true, straight, and plumb within 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 both beams are verified to be straight & plumb within 3/8", 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 guideway 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.
