Analysis on the Synchronization Control Method of the Crane System of 1 000 t Beam Lifting Machine

In the process of bridge erection facilities, in order to meet the lifting and moving conditions of prefabricated box girder, various large-scale beam moving machines have emerged. The TLMEL 1 000 t tire-type beam moving machine is a large-scale lifting and handling equipment independently developed and produced by Qinhuangdao Tianye Tonglian Heavy Industry Technology Co., Ltd., Considering the method of lifting box beams and the requirements of beam transportation conditions, it uses two cranes to work in coordination. In order to ensure the safety and stability during the lifting and transfer of the prefabricated whole-hole box girder, this time, the various motion units of the crane system of this TLMEL 1 000 t tire-type beam moving machine are studied and the method of synchronous control is analyzed.
