Dynamic Probing Rig DPL, DPM, DPH, DPSH and SPT

Dynamic penetrometer is very universal device for soil testing acc to EN standards. The probing rig can be used for soil-bearing capacity tests, compaction tests and for soil sampling.

It allows for DPL, DPM, DPH and DPSH soil investigation. Also using the additional tools , the SPT probing can be carried out.

This dynamic probing rig can be transported manually on robust pneumatic-tyred wheels. At the probing point the mast is erected and is set up to the correct vertical position by means of three crank legs (SPT) and an air bubble level.

Various rod systems according to local standards can be employed, a blow counter helps with taking the reading. The conversion to different weight and drop standards is quickly achieved by mounting or removing of additional drop weight bodies or drop height adaptors.

The drop weight assembly is lifted by means of a rope winch with hand crank or by hydraulic motor (LMSR-Hk version).

The penetrometer is also suitable for WINDOW SAMPLING up to 80 mm !

Sampling is carried out by using window sampling tubes or slotted probing rods which are driven into the soil by means of the a drop weight.
