LTM 1070-4.2

A small 4-axle crane with giant potential.

The LTM 1070-4.2 is equipped with cutting-edge technology—ECOmode and ECOdrive, which significantly reduce both fuel consumption and operational noise. Its well-established TELEMATIK single-cylinder telescoping system allows for the easy and automatic extension of the telescopic boom to the desired length. Additionally, the innovative, speed-dependent rear-axle steering enhances the crane’s off-road capabilities and greatly increases its maneuverability. This 4-axle crane can transport the majority of its ballast on roads, ensuring it is ready for immediate operation upon arrival at the site. Thus, the smallest of our 4-axle cranes is brimming with potential.

Technology

ECO mode

ECOmode is designed to optimize the efficiency of crane operations by minimizing fuel consumption and reducing noise emissions. This feature allows the crane operator to set the desired working speed using a control lever. Based on this input, the crane’s control system then calculates the optimal engine speed for the diesel engine. This not only conserves fuel but also lessens the environmental impact of the crane’s operation, making it ideal for urban and sensitive environments.

ECO drive

ECOdrive enhances the comfort and quietness of the mobile crane by lowering the engine speed. This feature improves the driving experience, especially in offroad conditions, by enabling faster gear shifting which in turn provides better dynamics and traction. When on the road, ECOdrive utilizes the torque from the Liebherr diesel engine more efficiently, thereby reducing overall fuel consumption and contributing to cost savings and environmental stewardship.

Single-engine concept

The single-engine concept is a sophisticated design that enhances the lifting capacity of the crane. Traditionally, cranes required two separate engines for the undercarriage and the superstructure. However, by powering the superstructure via the undercarriage engine and routing gear shafts from the distributor gear in the substructure through two mitre gears to the pump distributor gear in the superstructure, it’s possible to eliminate one engine. This not only reduces weight but also improves fuel efficiency and increases the crane’s lifting capacity.

Hillstart-Aid

Hillstart-Aid is a crucial feature for mobile cranes that often operate in challenging terrains. This system assists the crane operator by preventing the crane from rolling backward when starting on a gradient. It ensures a safer and smoother transition from a stationary position to moving forward, thereby enhancing operational safety and reducing the risk of accidents on slopes.

VarioBase® Plus

VarioBase® Plus represents an evolution in the design of crane bases. By integrating VarioBase technology with the crane’s structural steelwork, a trapezoidal support system combined with various support bases is created. This setup offers significantly higher lifting capacities, particularly over the crane’s rear outriggers. It allows for more flexible and safer crane operations, particularly in confined spaces where maximum stability is required.

AutoBallast

The AutoBallast function revolutionizes the ballasting process of cranes by automating it entirely. With just one press of a button, all the necessary steps to complete the ballasting are executed automatically. This not only speeds up the setup time of the crane but also reduces manual errors, ensuring that the crane is always properly balanced for maximum operational efficiency and safety.
