6.3 Low headroom trolley
When installing a low headroom trolley, the wheel gauge has to be adjusted properly. Clearance between
the wheel flange and the main girder flange (measure X) must be 3…5 mm. Ensure that the clearance is
equal on both ends of the trolley.

• Remove the temporary transport supports. Take the hoist out of the packing and move it to the
installation site. Lift the hoist using the lifting lugs (4).
• Loosen the locking (1) on frame tubes of the trolley drive side. Loosen the lowest fixing screws (2) for
the fixing brackets. Adjust the distance between the travel wheels (A) so that it is slightly wider than
the beam flange (B) for installation purposes.
!
Do not unscrew the fixing screws for the fixing bracket on the hoisting machinery side!
• Lift the hoist onto the beam. Adjust the X measurement until there is a gap of approximately 3…5mm
between the flange of the travel wheels and the flange of the beam. Use a nylon mallet to adjust the X
measurement.
• Check the wheels of the trolley are correctly aligned.
