6) Adjust the trolley for the beam’s flange width as follows:
Refer to Table 3-2 and select dimensions “A” and “C” corresponding to the beam’s flange
width “B”.
Loosen the Screws (D) that attach the Stiffening Plates (E) to Side Plates (F) and loosen the
Lock-Nuts (G) on the Stirrups (H) that secure the Side Plates (F) to the Load Bars (J) so that
the Side Plates (F) can move freely along the Load Bars (J) (see Figures 3-14 and 3-15).
Slide the Side Plates (F) along the Load Bars (J) so that dimensions “A” and “C” match the
values in Table 3-2 for the beam flange width. Verify that the distance “L” between the trolley
wheel flanges is a maximum of 5/32” (4 mm) wider than the beam flange width. Mark the
Stirrups (H) locations on the Load Bars (J) for future reference.
On the Cable Trough side ONLY, use a torque wrench to fully tighten the Screws (D) attaching
the Stiffening Plates (E) and the Locking Nuts (G) of stirrups (H) to the specified torque values
shown in the Table 3-3.
