Vibrating

For this pile driving method a vibrator brings the piling element into harmonious longitudinal oscillation. This oscillation is transferred from the piling element to the directly adjacent soil. Thus, the friction along the piling element is significantly reduced during the pile driving process. Due to the weight of the vibrator or pushing with the help of the crowd system the piling element can be installed in the ground. The piling elements can also be extracted following the same principle.

When using high-frequency vibrators with variable static moment, noise and vibrations levels are especially low. Subsequently, it is also possible to carry out vibrating work directly next to sensitive buildings. If the vibrator is guided on a leader, crowd forces can be transferred.

Leader guided vibrating

The high-frequency vibrator is guided directly on the leader, which allows precise installation of the piling element.

Sheet pile walls

Steel sheet piles are installed for temporary or permanent supporting and securing measures.

Auxiliary winch

The auxiliary winch of an LRB carrier machine lifts sheet piles into position. These are attached to the vibrator by clamping tongs.

Vibrated cast-in-place pile

A vibratory hammer installs a steel pipe with a disposable base plate in the ground. After concrete has been pumped in through the pipe, it is extracted again through vibration.

Ring vibrator

The ring vibrator allows installation of piles exceeding the leader length. The reinforcement cage can be inserted before concreting and without disconnecting the vibrator.

Free-hanging vibratory hammer

Vibrators may also work free-hanging on a duty cycle crawler crane.

Swinging leader

The swinging leader hangs on the duty cycle crawler crane via a special traverse. This method is suitable for pile driving work with very large inclinations.

Fixed leader

A special fixed leader is attached to the boom of the duty cycle crawler crane. The vibrator is guided by the leader so transferring crowd forces. This method is suitable for especially long piling elements.

Flushing container

Flushing with water or air reduces the resistance during installation and so increases the performance for pile driving.

Flushing lines

Flushing lines are welded to the lower end of the piling element. A flushing container supplies the lines with the flushing medium.

Animation video: LRB 16 / LRB 18

One of the most common types of application for the LRB 16 / LRB 18 is the installation of slurry walls.

LV 20 vibrator slim design

The Liebherr vibrator LV 20 achieves a static moment of up to 20 kgm. The maximum centrifugal force amounts to 1160 kN. Thanks to the use of new materials it is subject to low wear. In addition a new cooling system significantly increases its service life.
