With the H 15 L, the first hydraulic free-fall hammer developed and manufactured in-house, Liebherr consolidates its position as a full-service provider in the deep foundation industry. The hammer is currently the largest model of three in the new series and has a maximum impact energy of 225 kNm.

Key advantages of the attachment include the modular weights, whereby the hammer can be perfectly adapted to the respective piling requirements. Thanks to the short and lightweight design, the hammer is extremely efficient as well as user-friendly in terms of transportation and maintenance. As a standard, the pile helmet is soundproof.

The modern concept of the new fixed leader enables an extremely diverse range of applications and thus covers some of the most common deep foundation processes. In addition to piling work with a hammer or a vibrator, these include drilling operations with continuous flight auger or down-the-hole hammer, as well as diverse procedures for soil improvement such as soil mixing and cutter soil mixing.

A high degree of stability is ensured through the lattice boom design and also by the fact that the kicker is secured via supporting tubes at the boom head.

The leader elements of the LRH 600 impress with easy and quick assembly by means of pin connections.

Two compensating cylinders ensure that the leader always remains parallel to the uppercarriage, so providing maximum torque transmission. Inclination and radius can be adjusted using another pair of cylinders.

With a fixed leader the LRH 600 achieves an effective working length of 51 m and a maximum radius of 15 m. Thanks to the clever leader kinematics inclinations of up to 14° backwards and 9.5° forwards are possible. The pull force extends to roughly 120 t.

With the LR 1300, the most popular Liebherr crawler crane in the 300-tonne category is used as a carrier machine. The crane is powered by a 390 kW / 530 hp Liebherr diesel engine. A significant advantage is its quick transport. The innovative self-loading and self-assembly system, consisting of four fold-out jack-up cylinders on the undercarriage, an assembly cylinder in the A-frame for unloading, as well as two counterweight cylinders at the rear of the basic machine, make a huge contribution here. Cost-effective transportation of the LR 1300 on standard low-loaders is possible thanks to the maximum transport width of 3 m.

With only a slight modification both the LR 1300 and the duty cycle crawler crane HS 895 HD can be used as a basic machine. Owing to their high engine power, the hammer can be operated directly from the on-board hydraulic system, thus no additional power pack is required.

The innovative control of the attachment H 15 L is perfectly integrated in the system of the Liebherr basic machines. This allows for better adjustment in accordance with the respective conditions and thus ensures more efficient operation.

With the PDE process data recording system machine data is recorded during the working process. Using PDR the data can be managed, displayed, either tabularly or graphically, and analyzed. In combination with the telematics system LiDAT these reports can be easily generated from the office.
