Guided Hook

Guided Hook allows the load hook to be moved by hand. By tilting the hook block, the operator can easily specify the direction of travel. Travel movements are possible in both slewing and trolley directions. Turning the hook block clockwise or anticlockwise also makes it possible to move the hook up and down.

The assistant reduces the need for constant communication between the crane operator and slinger by allowing the slinger to guide the hook to the load themselves. This reduces the likelihood of errors and misunderstandings, which increases efficiency and safety on site.

The photo shows a construction worker wearing a yellow Liebherr safety helmet, gloves, and safety equipment. He is looking up and giving clear hand signals with both hands to coordinate the crane's movements. Parts of buildings, power poles, and parts of a crane can be seen in the background.

Fewer communication errors between crane operator and slinger
Communication errors between the crane operator and load slinger can lead to misunderstandings and inefficient work processes on large and loud construction sites, especially when it comes to precise positioning of the hook.

Solution: Guided Hook
The assistant reduces the need for constant communication by allowing the slinger to guide the hook to the load themselves. This reduces the likelihood of errors and misunderstandings, which increases efficiency and safety.

The photo shows the view from inside a modern crane operator's cab. The large glass surfaces allow a view of the construction site below, including building structures and materials. In the foreground are the driver's seat and two ergonomic control levers.

Safe and precise work with limited visibility
On sites where the crane operator doesn’t have a direct view of the load or hook, e.g. when working behind large structures or in enclosed areas, positioning the hook is often difficult and subject to error.

Solution: Guided Hook
The assistant allows the slinger to guide the hook to the load by hand without the crane operator needing to provide visual input. This increases safety and precision, especially in complex environments where visibility is limited.

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. — Sway Control & Sway Control Plus

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

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

The crane operator is responsible for lifting and moving the load safely. The assistance systems are there to provide support. Liebherr recommends that crane operators undergo crane operator training.
The assistance systems are not always useful in all lifting situations, e.g. in confined areas, which is why they can be activated and deactivated at any time.
