Static penetration test CPT crawler-truck

The CPT crawler-truck is a professional equipment used for geotechnical investigation for cone penetrtion test.

The CPT crawler-truck is constructed of Track chassis, 2 sets diesel engine, hydraulic supporting system, 2sets hydraulic Anchor mechanism, controller, platform, driving mechanism.

This equipment is an ideal equipment for static penetration test, it also can perform Pore pressure static test, DMT test, vane shear test, press-in wave speed test.

The CPT test has below functions:

  1. Soil classification
  2. Classify the soil type in mechanical basis
  3. Provide the physical index of foundation correlated to depth
