1. are specially designed for conducting high quality CPT(U) soundings under various operation constraints;

2. crawler type and wheel type;

3. can be equipped with data acquisition system.

4. 150KN, 200KN, 250KN;

Wheel type CPT vehicle (TPC-15W, TPC-20W)
Wheel type CPT vehicle uses hydraulic transmission system to penetrate, anchor, level and lift car body, etc.
The hydraulic system's oil is supplied by a large flow and high-pressure gear pump with an advanced directioncontrolling combination multi-way valve which is installed in the console center. Each a hydraulic valve controls one circuit. On the right of multi-way valve, the relief valve is installed to control the oil pressure.
The operation panel has two layers. The upper is the main control circuit while the lower is oil cylinder control circuit. On the upper layer there are three control rods: the left one to control penetration system; the middle one to control the anchor system; the right one to control the hydraulic props. The lower four rods is to control oil cylinder.

Crawler type CPT Vehicle (TPC-20L/TPC-25L)
Crawler type CPT vehicle shares the same working principle with other CPT machine. It uses Hydraulic transmission technology and uniformly pushes CPT cone attached with electric resistance strain chip to the soil. The electric resistance strain chip will transduce the resistance between the cone and the soil layer to electrical signal which will be transmitted to data acquisition system for reading, recording and confirming the mechanical parameters of foundation design.
Novel and compact design, small size with high power -- all in crawler type CPT vehicle the features of which are as set
forth below:
1.By using this vehicle, operating CPT test in severe environment (such as beach, river bank, sand fi eld, paddy field, etc) becomes so easy. Driving on icy roads also won’t be a problem.
2.Advanced hydraulic system: with direction-controlling combination multi-way valve, it is compact, small and easy to install.
3.Unique hydraulic anchoring device: high-power motor directly runs the screw mandrel to anchor which is handy and time-saving.
4.Gliding rod case: while penetrating, it can be glided out effortlessly. This could enlarge the working space and make loading and unloading convenient. Also it can be pulled back easily while the vehicle’s walking.
5.This vehicle is ideal not only for CPT test but also other in situ tests, with corresponding attachments and accessories,
like CPTu test, PMT, DMT, VCT, WVT, etc
