Tower crane LTM 1120-4.2

telescopicadjustableboom

Overview
The LTM 1120-4.2 delivers maximum performance on four axles. Its 66 m telescopic boom is the longest in its class and provides very high lifting capacities in raised positions, increasing operational flexibility and reducing transport costs by avoiding the need for a 5-axle crane. It is suitable for erecting radio masts and tower cranes and integrates proven technologies such as VarioBase® and VarioBallast®.

Key highlights

• Most powerful 4-axle crane in its class with high lifting capacities.
• Longest telescopic boom in class for extended reach and high hoist heights.
• VarioBase® support technology for variable outrigger configurations and increased capacities.
• VarioBallast® mechanically adjustable ballast system for space-saving and access to narrow sites.
• LICCON3 control system (third generation) with telematics readiness.

What’s inside

• LICCON3: third generation LICCON control with faster data bus, larger memory and higher processing power.
• Powerful: low gross vehicle weight with high lifting capacity (120 t).
• Telescopic boom: 66 m maximum length, longest in this crane class.
• Variable support: VarioBase® allowing higher lifting capacities, especially over the outriggers.
• Economical and flexible: mechanically adjustable VarioBallast® reduces required ballast and enables work in narrow sites.
• Wear-free manoeuvring: DynamicPerform clutch module on the TraXon gearbox transmits engine power via oil-cooled integrated disks.

Applications / Driving conditions

• On-road driving and jobsite driving (suitable for both road transport and site operation).
• Designed to perform tasks that would normally require larger cranes, reducing logistics and transport effort.

Technology and assistance systems

• ECOmode: minimises fuel consumption and noise by adapting engine speed to operating conditions.
• ECOdrive: reduces engine speed for comfort and efficiency; improves offroad traction and shifting dynamics.
• Hillstart-Aid: simplifies starts on gradients and prevents rollback.
• RemoteDrive: remote control for operation outside the cab for improved visibility and safer manoeuvring.
• VarioBase®: variable support system allowing different outrigger extension lengths for increased safety and capacity in confined spaces.
• VarioBallast® / AutoBallast: mechanically adjustable and automatic ballast systems for fast ballast changes.
• WindSpeed load charts: lifting capacity tables for different wind speeds.
• HVO ready: capable of running on HVO to significantly reduce CO2 emissions.
• Driver assistance systems: additional assistance functions for road safety.
