Installation steps of gantry crane track

Installation steps of gantry crane track

1. According to the design of the location, elevation installation track, Before the rail is laid, check the end face, straightness and distortion of the rail, Qualified rear can be laid. Before installation, the installation datum line of track shall be determined, and the installation datum line of track shall be the locating axis of crane beam.
2. The laying of a track structure on a steel beam, the actual center line of the track shall not be greater than 10mm of the actual center line of the steel beam, and shall not be greater than half of the steel beam web thickness.
3. The track is laid on the steel beam, and the bottom of the track should be attached to the top of the steel beam. When there is a gap and the length exceeds 200mm, pad should be added. The length of the shim shall not be less than 100 mm, the width shall be greater than the track bottom 10–20 mm, and each group shall be no more than 3 layers, after welding, fix with the steel beam.
4. Track the actual center line to install line horizontal position deviation, for general gantry crane should not be greater than 5 mm.
5. When the span of Gantry crane is less than or equal to 10m, the allowable deviation of track span is + 3 mm.
6. When the Gantry crane span is greater than 10m, the deviation shall be calculated by press type, but the maximum shall not exceed 15 mm.
7. The top of the track in relation to its design position longitudinal inclination, General gantry crane should not be greater than 3 / 1000, every 2m measured a point, the whole trip should not be greater than 10 mm.
8. The elevation of reference points on the top of track allowable deviation relative to design elevation, For universal gantry cranes, it is + 10 mm. The relative difference between the two parallel tracks of the same cross section, For universal gantry cranes, it is + 10 mm.
9. The joint position of the two parallel track shall be staggered, The stagger distance shall not equal the base distance between the front and rear wheels of a crane.
