Liebherr’s new LB 44-510 rotary drilling rig at Conexpo

718 Liebherr’s new 173tonne LB 44-510 rotary drilling rig offers 510kNm of torque, while the model’s in-house manufactured hydraulic drive provides automated torque adjustment, optimal continuous speed and four electronically adjustable speed ranges.

The LB 44-510 has been designed for drilling diameters of up to 3M and up to 92m drilling depths. The drilling rig is driven by a 505kW Stage IIIB/ Tier 4i V8 diesel engine.

If required, the LB 44-510 can be disassembled into single parts weighing up to 41tonnes; so the rotary drilling rig can easily be transported throughout the world. As the leader can be folded back for transport with all hydraulic hoses connected and ropes reeved, no disassembly is required when moving the equipment between job sites.
