The penetrometer pusher is powered by a diesel-hydraulic power-pack. The power-pack comprises an electrically started Hatz 1-cylinder direct-injected diesel engine (9.6 kW @ 3000 RPM) incorporated in silent-pack housing.

The engine, installed on 4 shock-absorbing engine supports, drives a Linde hydraulic pump by means of a propeller shaft and flanges. Large hydraulic oil reservoir with effective 2-stage filtering system.

• Engine performance: 9.6 kW (13.1 HP) at 3000 RPM acc. to DIN ISO 3046
• Fuel type: Diesel
• Fuel tank: 9 litres

• Noise level: 70 dB at 1500 RPM (CPT testing conditions)

• Starter type: Electric start
• Battery: 12 Vdc – 60 Ah

• Hydraulic tank: Capacity approx. 153 l with built-on combined hydraulic filter with air-breather, and magnetic element
• Hydraulic oil: Unil Hydro HVD46

4 ground anchors, which are screwed into the ground before testing and screwed out after testing, provide in general sufficient reaction force for the 200 kN pushing force of the penetrometer pusher when anchored in suitable grounds. Extra reaction force is obtained by using extension rods, anchors with larger blade diameter or by placing more anchors.

Anchor extension rods are used to increase the length of the ground anchor. They are most useful at sites where the soil at the surface is very weak, but the strength of the soil increases with a little depth. The extension rods can be invaluable at a site where there is a layer of fill covering stronger native soil. The extension rods have a female hexagonal drive on the bottom that pins to a ground anchor. On top it has a male hexagonal drive. The anchor extension rod is connected to the ground anchor using a high-strength bolt and nut (both included).

The CPT penetrometer set comes with a specially designed, two men operated hydraulic wrench for quick and effective placing of the ground anchors. The rotary drive (torque 1700 Nm) is mounted in the centre of the reaction arm of this hydraulic wrench. The wrench can be manoeuvred freely around the pusher and the ground anchors can be placed at that spot that suits the operator best.

The ground anchors are available with 3 different blade diameters, i.e. 220, 300 and 400 mm.

Only well places ground anchors can provide sufficient reaction force to benefit in full from the 200 kN pushing force of the CPT penetrometer pusher.

Anchor extension rods are used to increase the length of the ground anchor. They are most useful at sites where the soil at the surface is very weak, but the strength of the soil increases with a little depth. The extension rods can be invaluable at sites where there is a layer of fill covering stronger native soil.

Because of the conical shaped soil body on top of the anchor blade, it is recommended to respect a certain distance between the individual anchors in order to obtain optimum anchoring results. The greater the distance between the ground anchors, the more effective the anchoring in fact will be.

The 200 kN stand-alone CPT penetrometer set can be supplied with the following accessories and CPT equipment:

• Electrical CPT system with standard or piezocone
• Mechanical CPT system (continuous or discontinuous) with automated read-out
• Mechanical CPT system (discontinuous) with manual read-out
• CPT sounding tubes, casing tubes and cutting shoe
• Tilting construction, axle with large wheels and towing hook for easy manoeuvring on site (note: this is not suitable for on-road use)
• 2-axle trailer for transport of the diesel hydraulic power-pack, anchoring beams and tubes
• Pre-drill auger (D = 220 mm) to be used in combination with the hydraulic wrench and the extension rods in order to make a pre-drill hole, if required, prior to CPT testing
• Toolbox with toolset for maintenance and repair
• Manual in Dutch, English, French, German, Spanish or Portuguese

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.
