ABSTRACT:
A penetrometer frame for mounting on, for example, a truck and comprising a fixed part provided with slides which guide a moving part in the form of a frame which itself serves as a guide for a driving hammer and which may be raised or lowered by two hydraulic rams. The fixed part of the frame is pivoted on a platform about a horizontal pivot offset from the point where tubes are inserted or removed. The arrangement is such that extending the rams causes the penetrometer frame to pivot and allows access to the position at which tubes are inserted or removed.
