One of the features of the Liebherr Group is how decentralised it is and the diversity of products on offer. There are more than 130 companies in the group all over the world, although much of the construction machinery manufacturing is consolidated around Germany and neighbouring countries.

Different products are made in different locations and several of the factories are in remarkably scenic Alpine settings.

One of the Alpine factories is in Nenzing, home of Liebherr’s foundation machinery and duty-cycle crawler crane production. Liebherr-Werk Nenzing, one of six Liebherr companies in Austria, also has subsidiary operations in the UK town of Sunderland and in Rostock, in northernmost Germany. The Sunderland facility focuses on offshore cranes while the newer Rostock factory is where the LHM series mobile harbour cranes are made. In fact, some of the harbour cranes are still made in Nenzing, but the transitioning of production to Rostock is nearly complete.

Liebherr-Werk Nenzing is a €1 billion a year operation, employing more than 1500 people, plus a further 1,500 in Rostock and Sunderland combines.

A recent open day in Nenzing hosted approximately 500 customers from around the world to see two new machines unveiled. One was the HS 8130 HD duty-cycle crawler crane; the other was the LRB 355 piling and drilling rig. Alongside these new machines were dozens more on show from the Liebherr Nenzing product family, set against a mountainous backdrop so spectacular that the rain was unable to spoil the occasion.

The new crawler crane is the successor of the well-established HS 885 HD, one of the most successful models from the HS series over the past decade. The replacement model has been designed to be robust enough for punishing repetitive duty-cycle work and has two hydraulic free-fall winches offering 35 tonnes of line pull each. Maximum rated lifting capacity is 130 tonnes.

Liebherr says that the HS 8130 HD can be used for various special deep foundation applications as well as typical material handling tasks of a duty cycle crawler crane. These include working with slurry wall grab up to 35 tonnes and (as pictured below) with casing oscillator up to 3 metres. It can also be used for material loading with grab or drag bucket, and dynamic soil compaction as well as various dredging applications.

The LRB 355 is Liebherr’s largest combination piling & drilling rig, weighing 105 tonnes without attachments, with 450 kNm torque capability and 900 kN push/pull force. Maximum leader length is 32 metres.

The rig can be transported with the leader, multi sledge and rope still attached to the machine. All the winches are directly mounted on the leader, giving the operator a clearer view of the main winch and ensuring that the ropes do not move during leader adjustment.

The LRB 355 has been designed particularly for drilling with full displacement tool (see picture below). The rig can, however, also be used for drilling with Kelly equipment, double rotary head and continuous flight auger, soil mixing as well as piling jobs with vibrator and hydraulic hammer.

The Liebherr-Werk Nenzing open day also gave customers the opportunity to meet some of the new management team at the top of the company. Liebherr remains family owned and run. The company was founded by the late Hans Liebherr in 1949.  The company is today managed by Isolde Liebherr and her brother Willi Liebherr, two of the founder’s five children.  In 2012 four of the grandchildren joined the management board: namely Isolde’s daughters Patricia Ruef and Stéfanie Wohlfarth; and Willi’s son Jan Liebherr and daughter Sophie Albrecht. They are all in their thirties. Isolde Liebherr was accompanied by her daughter to the Nenzing event. Patricia Ruef gave a speech outlining the company’s core values of putting customer needs first. The success of the company, she said, was based on prioritising customers’ long-term requirements over any short-term desire for shareholder profits.

Several of the customers visiting Nenzing that day told me that they had not bought Liebherr equipment before but were impressed by what they had seen and what they had learned. I expect that you will be able to see the HS 8130 HD and the LRB 355 at a construction site near you before too long.
