| Abstract: | Shanghai MQ2000 portal crane has been in operation for 10 years and the climbing system has aged already. For the safety of climbing process, we decide to rebuild the system. With scientific research and analysis of the existing problems, plans for modifications of the mechanical, electric and hydraulic systems were made and proved to be successful in improving the performance of the equipments through the electricity- hydraulic test and backout machine test. |
