In view of the problem of unbalanced pressure distribution on the contact surface of new sliding slewing bearing slide of the large-scale slewing floating crane, the paper puts forward a method that reasonably arranges the partition in the slide beam to balance the pressure distribution on the slide contact face.The finite element software is used to ana-lyze the partition arrangement type good for pressure balance distribution and summarize the partition layout rule.The verifi-cation test is designed to check correctness of the finite element contact calculation result.The test result indicates that the pressure distribution trend calculated by the finite element analysis is consistent with the measured result, proving that the design method for the pressure balance distribution of the slide is effective.
