CPT - Vane tester for CPT & VST driven by manpower though handle and chains is of the lightest and most convenient CPT apparatus which even can be moved to testing site by only two persons.

It is not only a CPT apparatus but also a perfect VST apparatus. So it supports both CPT and VCT.

It can be used in narrow field because of its small size and light weight. In addition it also works well even without power supply by using human power.

Rated penetration force: 30KN ( 3t ); Available depth: 30m (soft earth)

For CPT investigators should choose a single-bridge cone (only penetration resistance can be measured) or double-bridge cone (both the tip resistance and local friction can be measured), also you can choose the piezocone (pore pressure can be measured) for CPTU.

Vane Shear Test (VST) measuring range: 0 to 130KPa;

Vane size: 75× 150 ( mm ) (normal) or 75× 100 ( mm ) (special)
