Liebherr LR 1750

The Liebherr LR 1750 is a high-performance 750-ton class crawler crane, built for large-scale lifting applications in power plant construction, bridge building, offshore projects, and wind turbine installation. The crane features a strong lattice boom structure, which extends up to 140 meters (459 feet) in standard configuration. When configured with a luffing jib and derrick system, the maximum system height reaches 196 meters (643 feet), making it ideal for high-elevation lifts and heavy industrial applications.

The LR 1750 is powered by a Liebherr V8 diesel engine, delivering 505 kW (677 hp), ensuring high performance, fuel efficiency, and reliable operation under extreme loads. The hydraulic system is designed for precision control, allowing for smooth boom movements and stable load handling. The winches provide high line pull and fast lifting speeds, optimizing productivity on large-scale projects.

One of the standout features of the LR 1750 is its modular design, which allows for easy transportation and assembly on-site. The VarioTray counterweight system enables quick and efficient counterweight adjustments, reducing setup time and improving operational efficiency. The crawler undercarriage is engineered for maximum stability, ensuring excellent weight distribution on soft or uneven terrain.

The slewing system enables 360-degree continuous rotation, allowing for precise load positioning in complex job sites. The crane is equipped with Liebherr’s LICCON (Liebherr Computed Control) system, providing real-time load monitoring, automatic safety features, and crane operation assistance, ensuring maximum safety and efficiency.

Operator comfort is a priority, with a spacious, climate-controlled cab featuring an adjustable seat, ergonomic controls, and a touchscreen display for crane monitoring. The intelligent control system assists operators in optimizing lifting performance, ensuring smooth and secure lifting operations.

The Liebherr LR 1750 has been widely used in wind turbine assembly, capable of handling heavy nacelles and rotor blades at extreme heights. It is also commonly deployed in industrial construction, oil and gas projects, and infrastructure development, where high lifting capacity and stability are critical.

With its exceptional lifting performance, innovative control systems, and robust crawler design, the Liebherr LR 1750 remains a leading choice for complex and demanding heavy-lifting projects worldwide, ensuring efficiency, safety, and reliability in the most challenging environments.
