针对科威特海湾大桥1700t/60m混凝土预制箱梁的起吊和转运施工,秦皇岛天业通联重工科技有限公司独立研制了SC1700型轮胎式提梁机。该装备采用模块化设计,由2台具有850t承载能力的轮胎式提梁机联合组成总承载力1700t的超大型起重装备。该装备采用高强度门架结构保证整机的力学性能;采用4点起吊3点平衡的起吊方式,起升稳定;采用液压悬挂支撑系统,悬挂分组串联,以适应不平路面;采用独立转向系统,可实现90°原地转向;采用CAN总线无线通信控制技术,将液压驱动、液压转向、车架液压升降及液压起升卷扬等各子系统协调控制,形成一套机、电、液同步作业的网络控制系统。该装备与TP1700型双幅、变跨轮胎式运输车配套施工,目前已完成400余片预制箱梁的吊装任务。
In response to the lifting and transiting construction of 1700t / 60m concrete prefabricated box girder of Kuwait Gulf Bridge, Qinhuangdao Tianye Communication Heavy Industry Technology Co., Ltd. has independently developed SC1700 type tire-type lifting machine. The equipment is modular in design and consists of two large tire-lifting machines with a carrying capacity of 850 tons to form a very large lifting gear with a total carrying capacity of 1700 tons. The equipment uses high-strength gantry structure to ensure the mechanical properties of the machine; the use of 4:00 lifting 3:00 balanced lifting mode, lifting and stability; hydraulic suspension support system, suspension grouping in series to adapt to uneven road; using independent steering system, Can be turned 90 ° in situ; CAN bus using wireless communications control technology, the hydraulic drive, hydraulic steering, hydraulic jack frame and hoist and other subsystems and coordinated control to form a machine, electrical and hydraulic synchronization Network control system. The equipment and TP1700 double-width, variable cross-truck supporting the construction of vehicles, has completed more than 400 pieces of precast box girder lifting tasks.
