200 kN CPT Penetrometer Pusher for Use on Excavator

• Dimensions (L x W x H): 1390 x 465 x 2290 mm
• Weight (without accessories): 580 kg

• Hydraulic cylinders: 2 double-acting cylinders ● Bore ø = 90 mm ● Piston rod ø = 45 mm

• Calibrated CPT testing speed: 20 mm / sec
• Unloaded speeds (continuously variable): 0 – 165 mm / sec downwards, 0 – 125 mm / sec upwards

• Hydraulic capacity (max.): 200 kN (20 tons) during CPT testing, 260 kN (26 tons) during pulling
• Stroke of the hydraulic cylinders: 1350 mm

• Hydraulic valve 1: CPT testing speed – up and down
• Hydraulic valve 2: Unloaded speed – up and down
• Hydraulic valve 3: Hydraulic catch – engage and disengage (if fitted)

• Pressure gauge 1: Measures the pushing force (ø = 63 mm, glycerine-filled, range 0 – 250 kN)
• Pressure gauge 2: Measures the pulling force (ø = 63 mm, glycerine-filled, range 0 – 250 kN)

• Catching clamp (option): Cylinder 63/40/40, pressure reduced to 35 bar. Provided with a corrugated hardened tip and a pressure accumulator

NOTE:  The maximum effective pushing capacity of the stand-alone CPT penetrometer pusher depends on the effectiveness of the anchoring.

The 200 kN CPT penetrometer pusher 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
• 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.
