200 kN CPT Penetrometer Skid for Trucks

The 200 kN CPT penetrometer skid is an economical rig with full CPT testing capabilities. It can be mounted easily by the client on a carrying truck converting it into a CPT penetrometer truck. The CPT skid is suitable for both electrical and mechanical CPT testing.
 
The skid is fully autonomous due to its diesel-hydraulic power pack. The 200 kN CPT penetrometer pusher and the diesel-hydraulic power-pack are removable, so they can also be used for other kind of jobs as well (like e.g. nearshore CPT testing).
 
The skid comprises a 200 kN 2-cylinder CPT penetrometer pusher, a diesel-hydraulic power-pack with load-sensing pump, manually operated valves, mounting frame, stainless-steel housing for datalogger and computer, etc. Gouda-Geo can send over an experienced engineer to help mounting the unit on to the carrying truck.
 
 
CPT Penetrometer Pusher
 
A hydraulic CPT penetrometer pusher with a push capacity of 200 kN, comprising 2 vertical hydraulic cylinders, simultaneously operated with a stroke of 1350 mm. A thrust block connects the two cylinders and is capable of driving and pulling the CPT sounding tubes and casing tubes into and out of the ground.
 
A hydraulic control unit, mounted on a console near the CPT penetrometer pusher, allows the operator to control all functions.
 
The unit comes complete with a guiding tubes, to be applied between the penetrometer and ground level.
 
 
Power-Pack
 
The CPT penetrometer pusher is powered by a diesel-hydraulic power-pack. The power-pack comprises an electrically started Hatz 1-cylinder direct-injected diesel engine (9.5 kW @ 2800 RPM) incorporated in silent-pack housing. The engine, installed on 4 shock-absorbing engine supports, drives a Linde load-sensing pump by means of a propeller shaft and flanges. Large hydraulic oil reservoir with effective 2-stage filtering system.

International Standards, Safety and CE Marking

The CPT penetrometer rig is designed and built in accordance with national and international standards and regulations. It complies with the provisions of the EC Directive 2006/42/EG and is provided with CE marking certifying that it meets EU consumer safety, health and environmental requirements.
 
The rig is equipped with a 200 kN CPT penetrometer pusher suitable to accommodate the measuring equipment for all kinds of Cone Penetration Tests with a maximum pushing force of 200 kN, such as:

• Piezocone CPTU testing
• Electrical CPT testing with standard electric CPT cone
• Dissipation testing (when using a piezocone)
• Seismic SCPT(U) testing with a triaxial seismic adapter
• Magnetometer soil investigation
• Continuous and discontinuous mechanical CPT

The Cone Penetration Tests can be performed according to international standards like ISO 22476-1, ISO 22476-12, NF P94-113, Eurocode 7, ISSMGE standard, ASTM D3441-05, ASTM D5778-12, ASTM D6067-96, ASTM D7400-08, and alike. This includes of course Class 1 piezocone CPTU tests and dissipation tests.
 
The operating procedures of the machine are described in detailed, easy-to-read and well-illustrated user manuals.
