Liebherr Floating Unit Operation & The LR 1400 SX

Despite its size, the LR 1400 SX boasts a wide range of applications and demonstrates impressive flexibility. The LR 1400 SX showcases it's diverse uses being utilized on the Tangenvika river project in Norway. ​The longest railway bridge in Norway – Tangenvika. Building this 1,042-metre long prestressed concrete bridge, which spans a large land area and includes a wildlife crossing, requires true #liebherrpower. Two Liebherr machines are in action: the LR 1400 SX lifts the casing from the water to bring it into the vertical position. Afterwards, the piling and drilling rig LRB 355.1 is installing nearly 60 piles at an 11-degree incline in the ground. Now that’s what we call teamwork! This adaptability is facilitated by a modular counterweight system and various boom configurations. With a compact transport weight of 46 tons, the entire crane can be easily moved between job sites. The platform and railings remain attached to the upper carriage during transportation. The self-assembly system allows for rapid assembly. The Ground Pressure Visualization feature calculates the crane's current ground pressure in real-time and compares it with the specified safety limits for the relevant position. Additionally, the ground pressure can be reduced using ground pressure reduction plates.

Liebherr crawler cranes are certified for lifting operations on barges, and their application as floating cranes presents numerous new opportunities. Particularly in urban areas where space is limited, rivers can serve as alternative working platforms. Crawler cranes perform lifting operations on floating platforms, and the transportation of construction materials via the river helps to alleviate road congestion in city centers. Rivers in populated regions represent a significant area of opportunity for the floating LR series. Liebherr's floating crawler cranes exhibit remarkable versatility during the construction of river regulations, flood retention areas, drainage systems, and treatment plants. On jack-up platforms, crawler cranes function as working platforms for port expansion. In offshore wind farms, our LR crawler cranes are well-suited for placement on pontoons. For approximately one year, the IJsselmeer (Lake IJssel) in northern Netherlands was the site of an extraordinary project involving an LR 11350. The crawler crane successfully erected the entire "Westermeerwind" wind farm from a substantial jack-up platform, which included 48 Siemens wind turbines with a hub height of 95 meters. Liebherr crawler cranes are also utilized in ports, where their versatility as handling equipment is highly sought after. This is particularly evident in the heavy lift, general cargo, and project cargo sectors. It is common to see our LR crawler cranes in ports, especially for heavy lifting tasks such as handling components for oil platforms or wind turbine elements for offshore wind farms. For exceptionally heavy components that standard harbor cranes cannot manage, the LR crawler crane series is essential. While container handling is not the primary area of application, the crawler crane can effectively step in when needed, such as when a cargo handling crane is out of service. Equipping the crawler crane with the necessary lifting equipment requires minimal time.
