AI Technical Summary

Technical Problem

The existing crane track installation method makes the track susceptible to impact, the pressure plate bolts easy to loosen, and the leveling layer is difficult to control in terms of manual finishing accuracy, thus failing to meet the requirements for high-precision installation.

Method used

A steel plate is installed on the top of the concrete gantry beam. The leveling layer is higher than the lower surface of the steel plate but lower than the upper surface. It is connected to the track pressure plate, steel plate, leveling layer and concrete gantry beam by bolts. The elevation of the steel plate is precisely adjusted by adjusting nuts to ensure that the track and steel plate are in close contact and to avoid stress concentration.

Benefits of technology

Improve track installation accuracy, reduce local stress, ensure stable crane operation, and achieve high-precision track installation.
