The Duoprob 60 is a hydraulically powered unit that’s also used for extremely hard soils. It’s known for its excellent price-performance ratio.
The DUOPROB 60 operates very rapidly – one work cycle takes about 20 - 25 sec.
This machine assures professional soil sampling. Control of the unit is done by a control unit with a counter.
Functional Description:
|
Impact-ram system. The boring rod is hammered up to 75 cm (30“) deep into the ground by a high frequency (2500 blows/min.) hydraulic hammer
|
|
|
Then the boring rod is rotated and pulled up 30 cm (12“)
|
|
|
The soil sample from the range of 0-30 cm (12“) is put into Container I
|
|
|
The soil sample in the range of 30 – 60 cm (12“ to 24“) is placed into Container II by the automatic movement of two containers
|
|
|
The remaining 15 cm (6“) is discarded
|
|
|
It’s also possible to extract soil samples from 25-30 cm (10“-12“) deep without layer separation. In this case a mixture of 15 single bore samples is filled into each container
