Geotechnical site investigation rigs for static cone penetrometer with 200 kN pushing capacity

The crawler type static probe works in the same way as other hydraulic static probes; it uses hydraulic transmission technology to automatically press the probe probe into the soil layer at a constant speed, using the resistance of the probe to contact the soil layer, and transforming it into a power signal through resistance strain. On the ground, the instrument is used to measure, record, and determine the relevant mechanical parameters of the soil for basic design. It is suitable for working in soft soil, cohesive soil, old clay, loess, and sandy soil.

HW-20E hydraulic crawler static vehicle adopts many advantages of similar products at home and abroad, with novel design, compact structure, small size and high power, and has the following characteristics:

1. With track support and walking, static exploration work can be carried out in harsh environments such as beaches, river beaches, sand fields and paddy fields, and road surface ice can still walk.

2. The hydraulic system is advanced, and the multi-way reversing valve is divided into multiple parts. The structure is compact, the volume is small, the installation is convenient, the pressure loss is small, and the pressure overload characteristic of the relief valve is good.

3. The unique sliding hydraulic anchoring device is adopted. When the static penetration work is carried out, the hydraulic lower anchor device is gently slipped outside the vehicle, and the high-power anchor motor rotates the lower anchor. After the work is finished, the device can be recovered. ,Convenient,

4, the machine can be used in a multi-purpose machine, not only the ideal equipment for static penetration testing, configuration accessories, can be extended for pore pressure static testing (CPTU), self-drilling side pressure (PMT), flat shovel side expansion (DMT) In-situ tests such as cross-plate shear (VCT) and press-in wave velocity (WVT).
