Product range

Liebherr duty cycle crawler cranes can be used for a wide range of applications. As an optimal basic machine for deep foundation work, the crawler cranes can be equipped with slurry wall grabs or hydromills. With fixed and swinging leader, they are ideal for use as piling rigs. They become a drilling rig when fitted with pile grab and casing oscillator. With attached vibro-flot or tamper weights they are used for soil compaction.

New land evolves

After land reclamation the loose soil is compacted step by step using a vibro-flot. Through the vibration the soil grains change from their initial loose layering to a denser layering. This improves the subsoil of the building site.

Deep compaction

Metropolitana di Milano

SAOS is installing 6,300m² of slurry walls for the metro extension using a Liebherr HS 8100 with the corresponding Liebherr slurry wall grab, type HSG 5.

SAOS is excavating bites of 2,800 × 1,200mm with depths of up to 54m. At 130m² per day, the Liebherr package underlines its high productivity.

New ground for Jätkäsaarl, Helsinki

In order to improve the soil conditions, the Finnish company Takanen is applying the Liebherr duty cycle crawler crane HS 8130 with a 14-tonne dropweight. The weight was dropped from a height of 10 m in free fall onto the building area to be compacted.

Achieving an impact between 50 and 70 kN/ m², the ground was compacted down to a depth of 7 m. The weight hit the ground 110 times per hour, about 50,000 times during the whole project phase.

Impact compaction

Piling: Impact driving

The piling elements are installed dynamically. A hydraulic hammer, usually mounted on a piling rig with leader, impacts on the piling element with the aid of a ram mass. Impact driving is used for the same purpose as vibrating, whereby the hydraulic hammers currently available are able to transfer much higher forces.

Pile driving methods

Pile grab

Duty cycle crawler cranes are equipped with universal bored pile grabs when installing pile foundations with casing oscillators. These can be deployed for different soil conditions. The universal pile grabs are extremely robust and fitted with hard-wearing components.

A further advantage is that the body of the grab has a streamlined design so that a high falling speed can be achieved in water.

Fixed or swinging leader

The modern concept of the new leader impresses with easy and quick assembly by means of pin connections. A high degree of stability is ensured through the lattice boom design. The proven duty cycle crawler crane HS 8200 can be used as a carrier machine. The LRH 600 piling rig is particularly suitable for heavy piling operations with large radius.
