GTR 780 Standard
GTR780 DYNAMIC PROBING/ WINDOW SAMPLING RIG
This
compact unit features dynamic probing procedures following DIN and
SPT/AFNOR standards as well as efficient window sampling operations.
Mounted on a rubber chain crawler carriage it is able to negotiate
inclinations up to 30 degrees and to handle nearly all-terrain ground
conditions. Since all functions are hydraulically assisted it is truly
laid out for one-man operation. Two lateral rod boxes and special
attachments carry all relevant accessories like rod extraction jack,
slips/ball clamps, tools etc. . The fact that all equipment necessary
for the field work is on the machine eliminates the need for additional
transport and consumption of time.
A folding mast allows very limited transport dimension so the unit can
be transported in mid-size vans like Volkswagen T4 or similar.
