Requirements for overhead crane steel track beams

Nov 07, 2019
1. The mid-span verticality of the track beam is ≤h/500, and "h" is the beam height of the track beam.
 
2. The horizontal side bend of the track beam is ≤ l / 1500, and "l" is the beam length of the track beam.
 
3. The arch of the track beam is ≤10mm in the vertical direction.
 
4. The deviation of the center position of the track beam from the design positioning axis is ≤ 5mm. If the requirements are not met, the track beam should be adjusted before the track can be installed.
 
5. The height difference of the top surface of the same cross-section rail beam in the same span is ≤10mm at the support and ≤15m at other places.
 
6. The height difference of the top surface of the track beam between adjacent 2 columns is ≤ l/1500, and ≯ 10mm, "l" is the beam length of the track beam.
 
7. The joint height of the adjacent two rail beam joints, the height difference between the top surfaces of the two rail beams is ≤1mm, and the central lateral misalignment is ≤3mm.
