The JT-20 crawler static penetration tester is composed of a crawler chassis, a diesel engine, a hydraulic jacking system, and a controller, all assembled on a frame.
1. Main features
1. This machine has a wide range of use and can be used interchangeably with static probe components, reducing the number of personnel, reducing labor intensity and saving costs.
2. It is suitable for complex terrain and landforms such as beaches, river beaches, sandy land and paddy fields.
3. The unique hydraulic small crane structure can easily load and unload the penetrating cylinder when excavating miscellaneous soil.
4. The main component combination of the bulk static probe machine is adopted, which can also use the user's original bulk equipment to reduce costs.
5. Single cylinder power system, low fuel consumption.
6. This machine is not only an ideal equipment for static penetration testing, but also equipped with accessories, which can be used for hole pressure static testing, flat shovel side expansion, cross plate shear, and press-in wave velocity test.
7. The handle is centralized and easy to operate.
