The LB 25 unplugged is a deep foundation machine with an alternative drive concept. During operation the drilling rig can be connected to a conventional electric supply or powered by battery without a cable, therefore “unplugged”. There are no restrictions in performance and application of the machine when compared to the conventional version with diesel engine.
