摘要: Described is an excavator for excavating soil in which a problematic object, such as unexploded ordnance, may be present. The excavator comprises an assembly of mutually pivotable arms which is connected to a chassis, and a pivotably arranged excavator bucket. At least parts of the excavator bucket and the outermost arm are embodied in a substantially non-magnetizable material. The excavator bucket further comprises a measuring device of magnetometers which are positioned at a mutual distance and which are configured to measure the local magnetic field vectors. The magnetometers are connected to a computer via a data and power cable with interposing of a data collection unit for collecting the magnetic field vector data measured by the magnetometers. The measuring device is further configured to determine the vector difference between said local magnetic field vectors, wherein a vector difference differing from zero indicates a disruption of the earth's magnetic field by the object, allowing the presence thereof to be detected.
