Product Feature
The proven LB 28-320 drilling rig from Liebherr is used for the foundation of piles. Drilling with Kelly equipment, double rotary head and continuous flight auger are common methods. Among its main characteristics is the simple transport including folded leader as well as the wide working area thanks to the parallel kinematics. Additionally, the LB 28-320 has a robust leader which can easy handle high torques and great tractive forces of the rope crowed system. This ensures particularly fast operating cycles. At jobsite conditions with limited heights, such as under bridges or below power lines, the rig can be equipped with a shortened “low-head” leader.
