Liebherr R 956 special excavator impresses in Austria

– With a high lift capacity and high working height, the R 956 takes on the challenges offered by the Ragginger company’s construction sites.

Liebherr‘s Austrian customer Ragginger uses the R 956 crawler excavator for material handling and piledriving work for sheet pile walls. The 72-tonne excavator features a high lift capacity and a 15 m 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).

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. It was developed to suit the company’s exact requirements. Special equipment for the crawler excavator ensures maximum productivity for Austrian customers, who are also impressed by the quality and reliability of Liebherr machines.

The R 956 crawler excavator combines maximum performance with low fuel consumption, which is a necessity for our customer’s challenging construction sites. The machine is also equipped with a comfortable operator's cab offering a large number of functions for precision and safe work. 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. Customer has a variety of Liebherr machines at its disposal for successful execution of different types of construction projects.
