LTM 1750-9.1 - Wide range of uses with powerful boom systems.

  • Maximum lifting capacity:

    The 900 US t / 800 t upgrade delivers even more lifting capacity.

  • In the wind:

    The 900 US t / 800 t upgrade includes lifting capacity tables for three wind speeds.

  • Suitable for global mobility:

    To any site thanks to a wide range of configurations for driving on roads.

  • All alone:

    Fast, easy setup with small space requirements due to self-erection.

  • Completely flexible:

    Flexible support system using VarioBase®, and therefore enhanced safety.

  • Suitable for universal use:

    Extensive, modular boom system for every conceivable application.

LTM 1750-9.1

The 9-axle LTM 1750-9.1 can carry its complete telescopic boom for driving on public roads. Due to its high lifting capacities and variable room system, it can cover a wide range of jobs in industry, infrastructure and the energy sector. The crane achieves significant increases in lifting capacity using its Y-guying. The all-terrain crane is designed to ensure particularly short setup times and maximum mobility. The extensive comfort and safety equipment, such as lifting capacity table for various wind speeds, round off the concept for the LTM 1750-9.1. Since 2020, there has been an 800 t upgrade available, which makes this mobile crane significantly more powerful.

ECOdrive makes the mobile crane significantly more comfortable and quieter by reducing the engine speed. Faster gearshifting delivers greater dynamic and traction offroad. On the road, the torque from the Liebherr diesel engine is used efficiently to minimise fuel consumption.


VarioBase makes the crane’s support system variable. It enables each outrigger to be extended to a different length. This enhances safety – particularly in constricted spaces. And what's more, the crane’s lifting capacities are significantly increased, particularly over the outriggers and depending on the configuration.

Automatic erection of the luffing jib

We can provide a support function for erecting the luffing jib on larger LICCON 2 cranes. Activating the automatic erection system in the LICCON crane control system ensures that the adjustment winch is automatically adjusted by the control system as the telescopic boom is luffed.

WindSpeed load charts

Increased flexibility and safety by using lifting capacity tables with different maximum wind speeds.

Power lifting at a steel plant:

14 Liebherr cranes carried out a wide range of maintenance work at a steel plant. One of the biggest challenges was to replace an 80-tonne gantry crane track at a great height. Find out more

LTM 1750-9.1 dismantles enormous hanging scaffold on Cologne Cathedral:

Bergheim-based heavy haulage contractor Wasel made a deep impression during a difficult crane job on Cologne Cathedral. An enormous hanging scaffold on the north tower of the cathedral had to be dismantled at a height of around 100 metres. Find out more

Now even more powerful:

The LTM 1750-9.1 with the 800 t upgrade can now hoist even more. It now also has lifting capacity tables for three wind speeds. Find out more
