24 There were not so many electric examples around in other machines except cars and the LB 16 unplugged was the first machine in this deep construction business. That machine allowed us to gain experience and it also showed that it was the right time.” Drivetrain The LRH 100.1 unplugged, and its bigger brother, the LRH 200, are the world’s first battery-powered piling rigs. The deep foundation machines can be connected to and powered by a conventional electric supply – as with many other vehicles of the Liebherr brand – but they can also be powered by battery, without a cable – hence the nomenclature, unplugged. Compared with the conventional diesel engine version, there are no restrictions in performance. The bulk of the machine is made up of the carrier, which includes the cab and also houses the electric drivetrain – positioned in the same locations where the diesel engine and gearbox used to be, with a pair of battery packs on the upper deck. Protruding from the front of this carrier is a tall mast, the leader, in front of which is the hammer and hydraulic rig that is used to drive the piles into the ground against soil resistance. The piling operation simply involves using the electric motor to power the hydraulics that lift and accelerate the drop of a ram weight to deliver the impact energy multiple times until the piling is complete. “In the cabin, the operator has two joysticks and they can tell the system the ram stroke and the impacts per minute.
