Check flange width "B" and dimension "c" on the basis of the table and adjust the
trolley to the beam width if necessary.
– Observe here that the connection part (6) must be positioned centrally (to
dimension "c") between the trolley side cheeks ("e1" = "e2").
Adjustment work, dimension "c":
Loosen the nut (2).
Adjust dimension "c" with the nut (1).
Tighten the nut (2) to the prescribed tightening torque 159 lb
Adjustment work, connection part:
Loosen the nuts (5) and (9), then slide the connection part (6) on the connecting pin
(7) such that the dimensions "e1" and "e2" are equal on the left and right between the
trolley side cheeks (4) and the connection piece (6).
Do not tension panel (10)! To do so, lightly tighten the nuts (5) and then loosen once
more by one 1/4 revolution respectively. Tighten the nuts (9) against nuts (5) to the
prescribed tightening torque 159 lb
