Study on Slewing Control System for the 7500T Full Revolving Floating Crane

摘要

The full revolving floating crane is one of the most key equipment in the large floating ocean engineering ship. With the highly speed development of ocean oil, it was need rapidly. In this paper, the7500T large full revolving floating crane was regarded as the study object, and the field-bus technology T-LINK, MICREX-SX series PLC and Inverter VG7S was adopted to build slewing control system. T-LINK network for control system was introduced. The slewing control programs such as control logic, interlock logic and electric protection had been worked out, which makes it possible to monitor and control the large floating crane effectively.
