UNDERGROUND CONSTRUCTION DEVICE
An underground construction device includes a hydraulic assembly having an internal combustion engine and a hydraulic pump driven by the internal combustion engine, a work device connected with the hydraulic assembly in a hydraulic circuit for introducing material to be pile-driven into the ground, a clamping apparatus connected with the work device for holding a material to be pile-driven, in clamped manner, which device has a hydraulic clamping cylinder, as well as a controller for opening and closing the hydraulic clamping apparatus. A further hydraulic pump for building up the clamping pressure of the clamping cylinder of the clamping apparatus is provided, which pump is operated by an electric motor. A method operates such an underground construction device.
