法国阿兹布鲁克市中心250吨桥梁安装工程

在紧凑的时段内，Sarens 650吨履带吊在法国阿兹布鲁克市吊装并安装了这座人行天桥。



该项目位于交通与火车来往的市中心，操作必须在紧迫的时间段内完成。由于75米长的桥梁重达250吨，因此必须在现场进行操控，并安装于8条铁路线上方。

此次操作Sarens团队选择了配备有工况SSL的650吨SL3800履带式起重机。带有超起的SL3800具有出色的起重能力，此外其还易于在有限的空间内移动和组装。该起重机在吊装操作的前一周被调遣至现场。



操作期间起重机在不断的调试方位后于周末执行起重作业。为了避免使用吊耳，本次吊具是专门为该桥设计的。据项目经理Koen Rooms谈到，"吊具帮助我们减少了安装的时间，并使操作更加安全"。他补充说："为了精确执行操作，我们在预定吊装的前一天进行了试吊。此次项目桥梁的吊装半径为27米，安装于5小时内完成"。

Within a strict lifting window, Sarens 650T crawler crane moved and installed the walkway bridge in Hazebrouck, France

Located in the city center and having constant movement of traffic and trains, the operation had to be performed within a tight time frame. The 75m long bridge weighing 250T had to be maneuvered on-site and installed above 8 railway lines.

The Sarens team selected the SL3800, the 650T crawler crane with SSL configuration. SL3800 with superlift has excellent lifting capacity and easy to mobilise and assemble in a confined space. The crane was mobilised on site one week before the lift.

The lift was performed during the weekend with consecutive demobilisation of the crane. The tackle was designed specifically for the bridge to avoid using lifting lugs. According to Project Manager Koen Rooms, “The tackles helped us in reducing the time taken for installation and making the operation safer.” He adds, “A test lift was performed a day before the scheduled lift to precisely execute the operation. The bridge was lifted at a radius of 27m and installed in five hours.”
