KRUPP岸桥小车架变形的校正和改造

Correction and Improvement to Deformation of Trolley Frame of KRUPP Quayside Container Gantry Crane

广州港的一台KRUPP岸桥,其小车架金属结构由于使用时间长,承载大,运行过程中承受复杂的交变应力而产生了塑性变形,引发了小车运行机构的多种故障。在检测、测量的基础上,对变形的结构进行校正和加强,消除了故障和事故隐患。

The trolley frame of a KRUPP quayside container gantry crane employed in Guangzhou Port, which was resulted to the plastic deformation due to the long time employment and heavy loaded with the complicated interchanging stresses in running, made divers faults in the trolley moving gear. Based on testing results, the deformed structure was corrected and strengthened and the fault and its hidden problem were eliminated.
