Liebherr recently expanded its range of deep foundation machines by introducing the LRB 23 piling and drilling rig and a battery-powered variant of its LB 30 drilling rig. The LRB 23 bridges a gap between Liebherr’s LRB 16 and LRB 355, providing all-around deep foundation capabilities. The battery-powered LB 30 offers the same performance as the diesel-powered LB 30 while reducing emissions.

LRB 23 Does It All

From applications with a hydraulic or vibrator hammer to Kelly drilling, double rotary drilling, full displacement drilling, and continuous flight auger drilling, the LRB 23’s 804-horsepower (600-kilowatt) engine provides the power necessary for all types of deep foundation operations. The LRB 23’s pile length is 72.1 feet (22 meters). The pile and drilling rig can also be used for soil-mixing jobs.

Liebherr’s BAT 300 rotary drive produces 221,268 pounds-foot (300 kilonewton-meters) of torque and can withstand high-torque drilling operations. When Kelly drilling, LRB 23 operators can reference a real-time display in the cab that shows the Kelly bar’s locking recesses, along with the distance to the next locking recess. The LRB 23’s drilling assistant can also automate the concreting process with continuous flight auger drilling.

Battery-Electric Drilling With LB 30

The new LB 30 can run on battery power or be plugged into a construction site’s power supply; in either case, its performance is equal to the diesel-powered LB 30. The LB 30 offers four hours of unplugged working time when Kelly drilling. Drilling diameter is 11.2 ft (3.4 m) when the LB 30 is equipped with an optional extension for the drilling axis. Maximum drilling depth is 232 ft (70.7 m). To improve stability, an optional rear support is available, and Liebherr recently redesigned the modular rear counterweight.
