Liebherr LR 1350/1

The Liebherr LR 1350/1 crawler crane brings robust engineering and operational flexibility to heavy lifting operations with a maximum lifting capacity of 350 tons at a 6-meter radius. Built around Liebherr’s advanced crawler travel gear and boom technologies, it is well-suited for infrastructure, energy, and industrial projects requiring extensive lifting reach and high load capacities.

The travel mechanism includes a center section with two crawler carriers, each with 1.2-meter tracks (optional 1.5 meters), driven independently via two hydraulic axial piston motors with integrated planetary gearboxes. These motors are spring-loaded and feature hydraulically releasable brakes. The chains can be controlled either synchronously or oppositely for precise movement. An 8-ton central ballast, composed of two 4-ton slabs, provides additional stability.

The crane’s power comes from a 6-cylinder Liebherr diesel engine, model D846 A7, delivering 370 kW (503 hp) at 1900 rpm and 2355 Nm of torque between 1200 and 1500 rpm. The system complies with emission standards under 97/68/EG Stage 3A and EPA/CARB Tier 3. A 1400-liter fuel tank supports extended operations.

A comprehensive range of boom systems ensures versatility in deployment. The main boom system includes:

• Main Boom S2: up to 96 m for 300-ton load capacity, extendable to 108 m with a derrick.
• Main Boom SL: up to 102 m for 200-ton load, or 120 m with derrick.
• Luffing jib (V type): maximum 90 m for 200-ton load; paired with Winch V.
• Fixed jib (F type): 12–36 m for 60-ton capacity.
• Wind plant jib (HS): a 90-foot (27.4 m) boom for erecting wind power equipment.

Derrick System: required for extended boom configurations with dedicated counterweight trailers.

Its slewing system comprises up to five motors (standard three), each hydraulically controlled and equipped with spring-loaded brakes for smooth rotation. The crane’s auxiliary winches, including Winch II and Winch III, allow multiple reeving configurations and efficient lifting operations.

Operator comfort and control are paramount in the LR 1350/1. The crane cab is a fully enclosed structure, capable of swiveling sideways and tilting, equipped with climate control, ergonomic seats, and full instrumentation. Liebherr’s LICCON system ensures safe crane operation with real-time monitoring of load data, boom angles, hook height, and other safety metrics. Additional safety is provided by camera systems mounted at the winches and rear for full visibility.

Counterweight options include 125 t mounted directly on the superstructure, 210 t at 15 m via trailer BW, and suspended ballast options up to 205 t using suspended slabs. The hydraulic ballast assembly system allows for independent erection without requiring auxiliary lifting equipment.

With its adaptable boom combinations, reliable powertrain, and Liebherr’s intelligent crane control, the LR 1350/1 stands as a powerful solution for high-capacity lifting in energy, civil engineering, and industrial applications.
