Liebherr R 956 special excavator in Austria
Austria-based Ragginger company has picked a Liebherr R 956 crawler excavator to carry out material handling and piledriving work for sheet pile walls. The 72-tonne excavator features a high lift capacity and a 15m hook height to handle a variety of sheet pile walls and minimise the travel required. In addition, the VH-HD undercarriage with hydraulically adjustable gauge ensures excellent stability when removing sheet pile walls, while at the same time allowing easier transportation by road.
The crawler excavator is equipped with a special long, height-adjustable boom suitable for this application. The boom’s kinematics are ideal for piledriving work along sheet pile walls, ensuring a high working height close to the machine. Additionally, the boom makes possible a relatively low transport height for an excavator of this size – a key point for the customer, who needs to be mindful of the restrictions of moving construction machines by road, especially through tunnels.
Liebherr has increased the size of certain cylinders in the attachment, to ensure best possible handling of sheet pile walls. The hydraulic system has been specially designed for use with the piling tool. The hydraulic cab elevation gives the operator the best possible view, increasing site safety. With its versatile equipment, the R 956 VH-HD is even being used by the customer for demolition work with appropriate tools (pulveriser, concrete shear, sorting grapple or bucket).
Tailor-made in Colmar
Since 2020, the Liebherr Application Center has been designing customised products for a range of customers and developing tailor-made crawler excavators at the Liebherr-France SAS site in Colmar. One of these machines is the R 956 for Ragginger, which was developed to suit the company’s exact requirements.
Ragginger is a company specialising in earthworks, heavy loads, metalling and working with sheet pile walls. Sheet piling wall installation and removal and impact driving require high-precision handling of special tools and equipment. Ragginger has a variety of Liebherr machines at its disposal for the execution of different types of construction projects.
