Liebherr showcased its LB 30 unplugged drilling rig at Conexpo 2023. This battery-powered machine, as well as the LB 25 unplugged, are identical to their conventional version in terms of application possibilities, weight or transport; however they have the additional advantage of zero emission.
The two machines can be used for all common applications in the field of deep foundation. Thanks to the optional extension of the drilling axis, they can be deployed for drilling diameters of up to 3.4 m. The optional rear support and the new design of the modular rear counterweight ensure higher stability and longer service life.
Besides their standard design, both models are available in a low head version with a total height of 14.1 m, or as ultra-low head with only 7.7 m.
For battery operation, the charging cable only needs to be unplugged and, for unlimited operation, reconnected to the construction site power supply. The battery is designed for a working time of four hours in Kelly operation. Whether in battery or plugged-in operation, the drilling performance remains unchanged.
Another deep foundation equipment displayed at Conexpo was the LRB 23 pilling and drilling rig, which provides an engine output of 600 kW, making it suitable for common deep foundation works. Read more here.
