Abstract

By analyzing and summarizing the process and requirements of cross beam installation, an underwater three-direction positioning equipment is developed. Through three sets of hydraulic cylinders and MGE sliders combining hydraulic synchronizing lifting technique and computer communication technology, precise automatic positioning is achieved. The equipment can be used in positioning other similar large structures.

Keywords: CAN-bus, cross beam positioning, hydraulic synchronizing lifting, MGE sliders.
