Bauma 2007: New range of pure rotary drilling rigs
|
|
|
With the LB 28 large rotary drilling rig at Bauma 2007, Liebherr is to present the first in a completely new range of pure rotary drilling rigs. With what is known as the LB series, Liebherr now has the ideal complement to the existing range of LRB combined piling and drilling rigs. The concept behind the LB series rests on decades of experience in special civil engineering applications at Liebherr, and takes into account the toughest demands now placed on modern rotary drilling rigs. The LB series rigs are designed for operations using Kelly equipment, continuous flight augers and double rotary heads.
The new LB 28 rotary drilling rig is designed for drilling diameters of up to 2.5 m and drilling depths of up to 70 m. It has a torque of 28 mt. Its rope descent system with a 40-t retraction force is a major technical advantage, offering the user maximum power and reliability even under the toughest ground and operating conditions.
The sturdy, 90 cm wide leader design and the extremely robust kinematics with a wide system width are unique technical features on the LB 28. In contrast to comparable competitor machines of similar sizes, the LB 28 is therefore much more stable and robust and, by extension, is primed for the toughest demands placed on it in practice. For the user, this means more power but also reduced wear and thus an automatically longer machine lifespan. |
