Liebherr LR 11350

The Liebherr LR 11350 is one of the largest and most powerful crawler cranes in Liebherr’s fleet, offering a maximum lifting capacity of 1,350 tons. Designed for heavy industrial applications, it is commonly used in oil refineries, power plants, wind turbine installation, and large infrastructure projects. The crane features a maximum main boom length of 150 meters (492 feet), while the addition of a luffing jib can extend the system height to 228 meters (748 feet), making it suitable for ultra-high lifting operations.

Powered by two Liebherr V8 diesel engines, each delivering 505 kW (677 hp), the crane ensures consistent power output and efficient fuel consumption. The hydraulic high-pressure system enables precise boom movements and controlled load handling, even under extreme loads. The winches operate at speeds of up to 120 m/min, ensuring smooth and efficient lifting cycles. The slewing system allows for precise 360-degree rotation, making it adaptable to complex lifting scenarios.

The LR 11350 is equipped with Liebherr’s LICCON (Liebherr Computed Control) system, which provides real-time load monitoring, automated safety features, and enhanced crane control. The crane’s modular counterweight system ensures optimal load distribution, and its V-Frame® and VarioTray® counterweight systems allow for quick and efficient counterweight adjustments without the need for full disassembly. The hydraulic self-assembly system enables the crane to be erected and dismantled with minimal additional equipment, improving setup efficiency.

The crawler undercarriage is designed for stability and mobility, even on soft or uneven terrain. The high ground clearance and load-bearing tracks allow for easy maneuvering, while the crane’s variable track width enhances stability during lifting operations. The operator’s cab is ergonomically designed, featuring an adjustable seat, climate control, and an advanced touchscreen control panel that integrates with the LICCON system for precise crane operation.

The Liebherr LR 11350 has seen strong global demand, with several notable first deliveries. China purchased the world’s first LR 11350, marking a significant milestone for both Liebherr and the Chinese heavy-lifting industry. The second unit produced was also delivered to China, further reinforcing the country’s investment in high-capacity lifting equipment.

In Europe, Weldex purchased the first LR 11350-P1800, an enhanced version of the crane, and immediately deployed it for a wind power project in Eemshaven, Netherlands. Working alongside Mammoet, Weldex’s LR 11350-P1800 was tasked with lifting the 18-meter by 7-meter, 340-ton machine housing of a 6MW Repower wind turbine to a tower height of 110 meters. The gross weight, including the hook and tackle, totaled 378 tons. The crane successfully installed two test turbines, with plans for 48 additional turbines for the North Sea East offshore wind farm near Heligoland beginning in 2013.

In Southeast Asia, GTA purchased the first LR 11350 equipped with the PowerBoom system in Indonesia, marking the first of its kind in the region. This second GTA-owned LR 11350 strengthened their fleet for high-capacity infrastructure and energy projects. Similarly, in Vietnam, Vietsovpetro (VSP) acquired the first LR 11350 in 2009, which was deployed at their fabrication yard in Vung Tau for lifting operations during the construction of modules for the Hai Thach wellhead platform (WHP-HTI Jacket) in the Bien Dong 1 project.

With its exceptional lifting capabilities, advanced control systems, and robust design, the Liebherr LR 11350 is a top choice for the most demanding heavy-lifting applications worldwide, ensuring efficiency, safety, and reliability in extreme lifting conditions.
