近日,徐工千吨级履带式起重机在山东蓬莱再次挑战海洋工程吊装极限,与德马克3台履带式起重机联合作业,高负载行走,将长约60m,重达800多t的结构件,顺利吊接到距离约200m的导管架上,完成一次高难度的施工作业。因龙门吊、平移车等方法都不能实现超大结构件的吊接,施工方最终敲定采用“四车抬吊法”完成此项任务——徐工千吨级履带式起重机与德马克1250t级起重机居于重物前方,两台德马克500t级起重机居于次位。当日早晨,在徐工千吨级履带式起重机安装完180t超起配重后,四车吊钩就位,前后协同作业,将结构件提升至30m
Recently, Xugong kiloton crawler cranes in Shandong Penglai once again challenge the ceiling lifting of marine engineering, and Demark three crawler cranes work in conjunction with high-load walking, the length of about 60m, weighing over 800 t structural components, smooth hanging Received a distance of about 200m jacket, to complete a difficult construction operation. Due to the gantry crane, the translation of the car and other methods can not achieve large structural parts of the crane, the construction side finalized the use of “four-car lift law” to complete this task - Xugong kiloton crawler cranes and de Mark 1250t class crane Living in front of heavy objects, two Demark 500t crane living in second place. On the morning of the same day, after the Xugong kiloton crawler crane was installed with the 180t super-counterweight, the four-car hook was put in place to work together before and after lifting the structure up to 30m
