摘要

Improvements in the dynamic penetrometers for geotechnical studies, characterized by comprising a frame mounted on wheels where a drive motor of a drum is located in which is wound, in part, a cable through at the same time by a pulley located at the end of a arm, emerging with a slight inclination of the same frame, toward its upper part, the ends of the cable being joined together by a tensioner, so that it appears without continuity solution, the pulley having a longitudinal displacement on the arm when mounted on a fork provided with sliding lateral guides in grooves made in it, so that its movement in separation of the drum tense the cable and grip on the drum following its movement, and that its sliding in the direction of the drum, determines the loosening of the cable that remains sliding on the same and lacking movement.
