LIEBHERR Assistance systems for fast-erecting cranes

Safer. Smarter. Better: New assistance systems for fast-erecting cranes

New standards in the world of tower cranes

The new driver assistance systems for LIEBHERR fast-erecting cranes, which were presented at this year's Bauma trade fair in Munich, set new standards in the world of tower cranes.These patented innovations independently carry out semi-automated, simultaneous movements and significantly simplify work for the crane operator. This not only makes operation more precise and efficient, but also improves the overall quality of work on site.

The result: greater precision, improved safety, and a whole new quality of working on construction sites.

The photo shows a construction worker wearing a yellow hard hat and dark work jacket standing on a construction site and operating a yellow Liebherr radio remote control. He is looking up intently, presumably at the crane or the load. In the background, walls and building materials for a shell construction can be seen.

Sway Control & Sway Control Plus

The intelligent assistant supports sway-free operation by actively correcting sway, including that caused by wind and external factors. A precise IMU sensor system on the hook block enables it to detect and compensate for inclination and angular velocity. Sway Control Plus increases efficiency and safety, especially in the case of less experienced crane operators, by compensating for any lack of experience.

The image shows a graphic representation of a construction site scene: a crane is lifting a large solar panel while a construction worker stands on a roof and directs the crane operator with one hand. Fields, trees, and a building can be seen in the background under a clear sky with light clouds. The motif conveys safe and precise work with modern crane technology when lifting and placing sensitive components.

The image shows a stylized construction site scene by a river or lake. A crane lifts a large orange building component over the water, while a construction worker stands on the shore and directs the operation with hand signals. In the background are a bridge and several other cranes. The reflection of the load in the water emphasizes the precision of the movement.

Vertical Line Finder

Vertical Line Finder maximises safety and convenience when lifting loads. It prevents load sway caused by diagonal pull through automatically and optimally positioning the hook above the load’s centre of gravity. The system aligns the hook vertically, prevents collisions and protects sensitive components. As the assistant takes over the exact positioning process, it also takes the strain off the crane operator, which makes precision work much easier.

Guided Hook

Guided Hook allows the load hook to be moved intuitively by hand. By tilting the hook block slightly, the operator can control the direction of travel with precision. This reduces the amount of communication needed between the crane operator and slinger, as the hook is guided directly to the load. The result: fewer errors, more safety and faster working on site.

The image shows a stylized construction site scene: A construction worker wearing a hard hat and work clothes is manually operating the hook of a crane. A yellow circle and arrows are marked on the ground to indicate the direction of movement. On the right-hand side of the image is a packaged beam that is to be lifted. The scene illustrates the operating principle of the Liebherr Guided Hook assistance system, which allows the slinger to control the crane hook directly and precisely.

The image shows a stylized construction site scene in which a crane is precisely lifting a large slab over a pipe system. Two construction workers wearing helmets and high-visibility vests are supervising the process—one on the ground and one on scaffolding. Yellow lines in the background visualize the planned path of movement for the load.

Positioning Pilot

Positioning Pilot optimises construction site logistics with semi-automated travel movements. Stored points are approached with precision and routes travelled without sway. The IMU sensor system on the hook block assures a high degree of accuracy and safety. Up to three hook positions and two routes (moving forwards and back again, and including stops) make monotonous tasks like concreting and unloading easier. The crane operator’s workload is reduced, workflow is accelerated and safety standards are improved thanks to predefined movement routes.

Our proven assistance systems

Our proven assistance systems for construction sites are specifically designed to maximise accident prevention and safety. They effectively make life easier for operators and significantly increase everyday safety on site. Their precision control contributes to high handling performance whatever the task and helps optimise work processes.

Micromove

Micromove takes precision control to a whole new level and ensures loads are positioned with millimetre accuracy. Where complex lifting operations and sensitive components are involved, Micromove ensures maximum precision by giving the operator effortless control over the finest of adjustments. Loads can be moved without jolting, which increases quality and safety on site. Micromove makes challenging tasks easier and is an indispensable tool for precision tasks.

The photo shows a Liebherr tower crane safely lifting a large rectangular load into the air. The load is secured with ropes and straps and stands out clearly against the blue sky with light clouds. The low-angle shot emphasizes the size of the crane and the stability of the structure.

Load Plus

The Load-Plus function allows K series cranes to significantly increase their lifting capacity, so that even extra heavy loads can be moved safely without effort. This extra (up to 20% more) hook power is a real advantage for challenging tasks as the lifting capacity is increased without compromising efficiency. Load-Plus delivers powerful yet controlled lifting of heavy loads and offers extra flexibility, which is invaluable when every kilogram counts on site.

Speed2Lift

Speed2Lift increases lifting speed and optimises workflow through the faster movement of loads. This function makes lifting and lowering loads noticeably faster, which speeds up the entire construction site process. Work cycles are shortened and time and resources saved. Speed2Lift offers particular advantages for intensive projects as work processes are faster and more efficient, which in turn maximises productivity on site.

The photo shows several Liebherr tower cranes in operation on a large construction site in the middle of a city. The boom of a crane can be seen close up in the foreground, while other cranes are working above buildings and streets in the background.

Slew safety area limitation

Areas that need to be avoided when slewing with a load, e.g. rail tracks, preschools and power lines, can be easily and clearly excluded via the display. As every metre counts on site, the slew safety area limitation function offers multiple teach points so that your working area is defined with extra precision.

Lifting capacity reduction

The crane’s lifting capacity curve can be flexibly adapted to your construction site’s requirements. So you only pay for the lifting performance that is actually necessary. Lifting capacity reduction is a major plus for rental companies as it means that larger cranes can be hired out and flexibly adapted to meet different requirements as needed. This makes it possible to respond to customer requests in a targeted and cost-effective way.
