A Liebherr piling rig was recently used for foundation works for the construction of future apartment buildings in the Danish capital of Copenhagen. Three hundred piles had to be installed by the LRH 100, which belongs to the Danish construction company M.J. Eriksson A/S.
In a major infrastructure project called “Frederiks Brygge,” a waterfront area in the Southern docklands of Copenhagen is currently being redeveloped. In an area of approximately 120,000 square metres, 1,200 apartments are under construction, together with retail and commercial space.
The Liebherr LRH 100 piling rig was used for the installation of about 300 concrete piles with a diameter of 300 mm and total lengths between eight and 13m. Thanks to its performance, strength and flexibility, the LRH 100 was able to complete this job within just 15 working days – a considerable time ahead of schedule.
A major challenge on the job site was the sometimes-narrow workspace, offering little leeway for the piling rig to move in any direction. Here, the innovative parallel kinematics of the machine’s leader system with its great operational range proved to be an immense benefit for the customer. It allows radii of up to 8.75m and inclinations of maximum 18 degrees in all directions. Thanks to this feature, the operator was able to change the position of the leader in all directions without moving the undercarriage.
“We are overall happy with the performance of the LRH 100. Its ability to install the piles in different angles and in any direction as well as its long outreach massively contributed to the fast completion of the piling works at the jobsite,” said Kave Yazdani, engineer at M.J. Eriksson A/S.
The LRH 100 is based on the proven LB 20 carrier machine of the Liebherr LB series of rotary drilling rigs. It is equipped with a powerful and emission-optimized 270 kW/362 hp Liebherr diesel engine and can be transported in one piece with the hammer mounted. The compact design of the carrier machine with three-metre transport width allows for quick and cost-effective transportation. The LRH 100 also offers a wide range of powerful equipment. This assures that the excellent performance of the basic machine is ideally converted into high productivity.
