The Compact CPT Rig provides up to 100 kN effective pushing force and has a high reaction force due to four ground anchors. The CPT tower can be detached and then anchored to a floor, wall or ceiling when working in confined spaces. The CPT pushing rams can, therefore, be used for CPT testing separately from the Compact CPT Rig, which is used as a hydraulic power pack. www.sonicsampdrill.com
