Rotary drilling rig LB 36: Excellent performance and equipment features
At the Ankomak of this year in Ankara, Turkey, Liebherr displays the LB 36-410, which is part of Liebherr’s series of pure rotary drilling rigs. The machine, designed and manufactured in Nenzing, Austria, possesses unique features like a stable leader design, robust kinematics as well as a broad range of possible applications. Like all rigs of the LB series, the LB 36 has been specially designed for Kelly drilling, drilling with double rotary head, continuous flight auger as well as for soil mixing applications.
The LB 36, weighing approximately 115t, is designed for drilling diameters of up to 3m and drilling depths of maximum 88 m. Its rotary drive offers a torque of 410kNm. The powerful Kelly winch and the rope crowd system offer a significant technical advantage. The operator is thus provided with maximum performance and reliability even with the most difficult soils and under extreme operational conditions.
Special highlights of the Liebherr LB 36 are the solid design of the leader as well as extremely robust kinematics with a large cross section. The machine thus offers a remarkable high stability. Hence, the LB 36 considers even the heaviest demands, which are nowadays imposed on modern rotary drilling rigs. For the operator this results not only in high performance but also in less wear and therefore in a longer service-life of the machine.
Basic machine and leader can be transported in one piece. This allows for quick and easy transportation of the rigs and thus for flexibility in jobsite assignment. The time-saving quick assembly system for leader and crawler track assemblies of the LB 36, which is typical for Liebherr rotary drilling rigs, represents another significant advantage.
