시추기를 이용한 관입력은 약 2톤 정도로 저 비용으로 연약지반에 유용하지만 관입력이 작다. 앵커를 이용한 관입장치는 20톤까지 관입 가능하고 자중이 약 3톤으로 운송 비용이 자중 20톤 장치보다 작고 연약지반에 이동 가능하다.

 

20톤 무한 궤도형 관입기 (자중 3톤)

crawler-based CPT penetrometer pushing rig with rubber tracks, Hatz 3-cylinder diesel engine incorporated in a sound insulating enclosure, load-sensing hydraulic pump, a 200 kN CPT penetrometer pusher, unique anchoring system on reaction arm. Practically all functionalities are controlled by means of a wireless remote control.

 

 

 

 

Anchor extension rods are used to increase the length of the ground anchor.
