Crane track installation requirements for steel structure Crane Rail beams

(1) The mid-span verticality of the Crane Rail Beam is ≤h/500, where h is the beam height of the Crane Rail beam.

(2) The horizontal side bend of the Crane Rail beam is less than or equal to l/1500, and the net 10mm, l is the beam length of the Crane Rail beam.

(3) The vertical arch of the Crane Rail beam is less than or equal to 10mm.

(4) The deviation between the center position of the Crane Rail beam and the design positioning axis is less than or equal to 5mm. If it does not meet the requirements, the Crane Rail beam positioning should be adjusted before the track can be installed.

(5) The height difference of the top surface of the Crane Rail beam of the same cross section in the same span is ≤10mm at the support, and ≤15m at other places.

(6) The height difference of the top surface of the Crane Rail beam between two adjacent columns in the same row is ≤l/1500, and ≯10mm, where l is the beam length of the Crane Rail beam.

(7) At the joints of adjacent 2 Crane Rail beams, the height difference between the top surfaces of the 2 Crane Rail beams is ≤1mm, and the center lateral displacement is ≤3mm.
