LTM 1090-4.2 - The all-rounder travels around the world with low running costs.

Powerful:

High lifting capacities on four axles.
Single-engine concept:

The crane superstructure is powered by the engine in the undercarriage – meaning one less engine and therefore lower maintenance costs!
Lower fuel consumption and noise:

ECOmode and ECOdrive reduce fuel consumption and ensure low noise in action.
Variable support

VarioBase® support technology makes very higher standard lifting capacities possible.
VarioBallast®:

The adjustable ballast system delivers greater flexibility in action.

LTM 1090-4.2

Outstanding mobility, power and economy. These are the main features of the LTM 1090-4.2. It can be driven all over the world at low cost as it can be configured with a whole series of different axle loads for driving on roads and sites. ECOdrive and ECOmode reduce its fuel consumption and noise emissions – better for drivers and the environment! Our Liebherr VarioBallast® and VarioBase® innovations enhance its capacity, safety and flexibility.

Jobsite driving

ECOmode

ECOmode minimises both fuel consumption and noise emissions when operating the crane superstructure. The crane operator sets the required working speed using the control lever. The LICCON 2 control system calculates the perfect engine speed for the diesel engine.

ECOdrive

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.

Hillstart-Aid

Hillstart-Aid makes starting on gradients easier. Move off safely and easily without rolling backwards.

VarioBase®

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.

VarioBallast® (mechanical)

Mechanically slewing ballasting cylinders enable the ballast radius to be changed quickly to two different settings. The smaller radius is used in constricted conditions whilst the larger one is used if a higher lifting capacity is required. This significantly increases the crane’s flexibility.

AutoBallast

The AutoBallast function completes the ballasting process automatically. All the steps are carried out after the button has been pressed just once.

WindSpeed load charts

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

HVO ready

Up to 90 % lower CO2 emissions in action.

A new star in the 4-axle sky:

The LTM 1090-4.2 is a shining example of sophisticated mobile crane technology – high lifting capacities, variable driving states, ECOdrive, ECOmode, VarioBase®, VarioBallast® and much more make it a flexible, economical, powerful all-rounder. Find out more

LTM 1090-4.2 proves ideal in constricted site conditions:

The VarioBase® variable support base for Liebherr mobile cranes has established itself in practice as a solution to space problems on sites. The great benefits of VarioBase® in mobile crane contractors’ everyday life were demonstrated at two sites, one in Denmark and the other in Switzerland. Find out more
