A Show of Strength: Terex® CC 2400-1 and CC 2500-1 Lattice Boom Crawler Cranes Lift Steel Bridge at Largest Private Work Site in Switzerland


ZWEIBRÜCKEN, May 8, 2015 – To lift an 884-tonne, 162-meter-long connecting bridge between two buildings at the Coop distribution center in Schafisheim, Switzerland, crane service provider Toggenburger used the two largest cranes available in the country: Its Terex® CC 2400-1 and CC 2500-1 lattice boom crawler cranes.


“The individual bridge components had enormous gross weights of up to 275 tonnes and required us to use working radii of up to 29 meters, which made it absolutely necessary to use the largest crawler cranes available in all of Switzerland – our Terex CC 2400-1 and CC 2500-1 duo,” explains Toggenburger + Co AG Project Manager André Huber. Of course, the two cranes first needed to be transported to the work site in Schafisheim, which took a total of 48 trucks. Once there, Toggenburger’s experienced team and the ease of assembly of both cranes made it possible to set up the units in a mere two and a half days despite the limited space available and the fact that delivery operations continued at the premises. For the upcoming lifts, the seven-person team set up the CC 2400-1 crane with an SSL configuration featuring a main boom length of 48 meters, a counterweight of 160 tonnes, a central ballast of 40 tonnes, and an SL counterweight of 240 tonnes. The CC 2500-1 crane was configured almost identically. The only difference: The SL counterweight for the CC 2500-1 weighed 250 tonnes. A 130-tonne hydraulic crane was used as an assist crane.




Complex lift choreography

The way the premises were laid out made it impossible to lift the two-level bridge as a single unit over the road between the two buildings, so the manufacturer delivered the steel structure in the form of individual components instead. These components were welded together into a total of seven bridge elements at the work site. These elements were then placed on the bridge’s three piers in five lifts. “This required an extraordinary level of precision, since the tolerances for joining the individual elements were a matter of millimeters,” explains Toggenburger + Co AG’s Michael Dudler, who oversaw the project together with Huber. Special yokes were fabricated in order to pick up the elements. The design behind these yokes made it possible not only to attach hoist cables to them with shackles, but also to implement the complex approach used to align the bridge elements. This approach consisted of two elements being lifted simultaneously, with one element being rigidly rigged to one of the two cranes while the other crane supported an arrangement with 140-tonne strand jacks placed at three rigging points between the hoist cables and the yoke. These strand jacks, in turn, made it possible to precisely control the lateral and longitudinal position of the second element using hydraulic power. In addition, the bridge elements’ size made it necessary for the Toggenburger team to use Genie® aerial work platforms to rig the load-securing equipment. “Despite the sophisticated setup we had for maneuvering the loads, we were a little worried, because any strong winds would have prevented us from performing the lifts,” Dudler says. But the anxiety proved to be unwarranted, as the weather was magnificently inviting on both lifting days, with the result being that several hundred people gathered on the morning of Saturday, February 14, 2015, to watch the spectacular first two lifts at the site.


The Terex CC 2400-1 crawler crane started off by picking up double element 1/2 directly from the assembly site at a working radius of 18 meters. The crane then proceeded to lift the element, which had a total length of 55.5 meters and weighed 275 tonnes together with the corresponding load-securing devices, to a height of 12 meters before safely putting it down on the piers. During this operation, the crane operated at approximately 97% of its capacity. Meanwhile, the CC 2500-1 crane was responsible for bringing bridge element 3, which was 41 meters long and had a gross weight of 250 tonnes, to its installation position. A modular trailer was used to move the element forward from the assembly site, after which the crane picked it up at a working radius of 18 meters, lifted it, and set it down at the intended position. In this case, the crane operated at 74% of capacity. With this, the lifts planned for the day were completed as scheduled and the first half of the span – all the way to the center pier – was in place. “Afterwards we moved the cranes about a hundred meters forward so that they would be in place for the next day,” reports Huber.


When Sunday morning came, the team was prepared to carry out the remaining lifts. The CC 2400-1 crane lifted element 4 – which had a length of 22 meters, weighed 95 tonnes, and required load-securing equipment weighing 20 tonnes – at a working radius of 29 meters. Bridge elements 5/6, which were nearly 49 meters long and had a gross weight of 240 tonnes, were left to the CC 2500-1 crane, which used a working radius of 25 meters and operated at 83% of capacity to safely put them in place. Finally, the two crawler cranes left the 17.5-tonne final element 7 to the assist crane, which completed the final lift perfectly on schedule. “When you have the right machines, a good team, and professional planning, even the most demanding projects become routine. Of course, you’re still relieved at the end when everything goes smoothly!” say Huber and Dudler, who were visibly happy with the results.



About the Terex® CC 2500-1 lattice boom crawler crane

The Terex® CC 2500-1 is the most powerful lattice boom crawler crane in its class. It has a maximum lifting capacity of 500 tonnes, maximum load moment up to 6140 meter tonnes, and a maximum load radius of 146 meters with SSL/LSL 126 m + 36 m LF configuration. The CC 2500-1 crane stands out by virtue of its enormous load capacity and great flexibility, especially in Superlift configuration. Variable Superlift radius and variable offset for SW and SWSL boom combinations allow operation in an extended range of applications. Main boom length can be up to 126 meters, dependent on the model selected. By design, the crane’s weight is optimized for transport, at a maximum of 39 tonnes per section. The user-friendly IC-1 touchscreen crane control system is designed for simple and safe operation, for example it can calculate load capacities for intermediate main boom positions.



About the Terex® CC 2400-1 lattice boom crawler crane

The Terex® CC 2400-1 lattice boom crawler crane features a maximum lifting capacity of 400 tonnes and a maximum load moment of 5,168 mt. Equipped with a main boom, luffing fly jib, and Superlift equipment, the CC 2400-1 crane is one of the most powerful cranes in its class. Optional special components designed for erecting wind turbines, such as LF2 fixed fly jibs with lengths of 12, 24, or 36 meters in combination with two reinforced main boom sections, enable the crane to erect most 2-MW wind turbines with heights of up to 130 meters. For lifts in the petrochemical industry and for infrastructure projects, Terex offers a variable Superlift system that makes it particularly easy to quickly change Superlift working radiuses, allowing customers to benefit from lower counterweight transportation costs. The Superlift system can be combined with a telescopic Stinger system or a self-propelled counterweight carrier.
