LTM 1120-4.2 Transitions to LICCON3 Control System
Updated: Jan 1
30-Second Takeaway
Liebherr has upgraded the LTM 1120-4.2 all-terrain crane with the new LICCON3 control system, delivering enhanced computing power, modernized cab design, advanced driver assistance systems, and fleet connectivity. Retaining its 120-tonne lifting capacity and industry-leading 66-metre telescopic boom, the LTM 1120-4.2 remains the most powerful four-axle crane on the market while preparing operators for future digital and remote operation capabilities.
Maximum performance on four axles has long defined the Liebherr LTM 1120 series, and with the introduction of the LTM 1120-4.2, Liebherr continues that legacy while taking a major technological step forward. The latest version transitions to the third generation LICCON3 control system, pairing proven lifting performance with modern software architecture, enhanced connectivity, and a redesigned operator environment.
The LTM 1120-4.2 replaces the LTM 1120-4.1 without altering its core performance parameters, ensuring continuity for crane fleets while introducing future-ready technology.
Introduction of the LICCON3 Control System
With LICCON3 (Liebherr Computed Control), Liebherr modernizes its crane control platform through updated software and programming languages, a faster data bus, increased memory capacity, and significantly higher computing power.
Despite the technological leap, Liebherr has retained the familiar operating logic, allowing experienced operators to transition seamlessly. Proven hardware such as the BTT mobile operating and display unit remains in use, while a new large-format touchscreen in the superstructure cab improves clarity, usability, and information flow.
LICCON3 cranes are delivered telemetry-ready as standard, enabling fleet owners to access machine data, performance metrics, and operational history through the MyLiebherr customer portal, supporting proactive fleet management and maintenance planning.
Redesigned Driver’s Cabin and Crane Cab
Alongside LICCON3, Liebherr introduces a newly designed driver’s cabin and crane cab, focused on comfort, visibility, and modern ergonomics.
Key enhancements include:
Premium interior materials and a contemporary design
Multifunction steering wheel with integrated controls
Improved instrument layout for intuitive driving and crane operation
Remote key central locking with “Coming and Leaving Home” lighting functions
Automatic climate control with sun sensor for adaptive heating and cooling
LED lighting is now standard throughout the crane cab, offering improved illumination, reduced energy consumption, and longer service life.
LTM 1120-4.2: Maximum Performance on Four Axles
First introduced in 2020, the LTM 1120 platform redefined what was possible on four axles. The LTM 1120-4.2 continues to set the benchmark with a 66-metre telescopic boom, the longest ever fitted to a four-axle mobile crane.
This exceptional reach allows the crane to:
Erect tower cranes and radio masts efficiently
Achieve hook heights of up to 91 metres
Operate at working radii of up to 64 metres
The compact footprint makes the LTM 1120-4.2 ideal for urban environments and confined job sites where larger cranes cannot operate.
Liebherr’s VarioBase® and VarioBallast® systems further enhance flexibility and safety. VarioBallast® allows the ballast radius to be adjusted hydraulically, optimizing performance in tight spaces while reducing setup time and transport costs.
Innovations Focused on Customer Value
Beyond the control system upgrade, the LTM 1120-4.2 incorporates multiple technical enhancements aimed at efficiency, safety, and ease of ownership.
The TraXon DynamicPerform oil-cooled starting clutch ensures nearly wear-free operation of the modular ZF TraXon gearbox, improving driveline durability and smoothness.
New driver assistance systems, including the Blind Spot Information System and Moving Off Information System, significantly enhance road safety during transport and site maneuvering.
The crane is also prepared for RemoteDrive, enabling wireless external operation particularly valuable on congested job sites where visibility and positioning are critical.
Standard and optional features such as VarioBase®, central chassis lubrication, and digital tire pressure monitoring further reinforce Liebherr’s focus on uptime, safety, and long-term fleet reliability.
