HR 260 Drilling Rig
Drilling large diameters and great depths with augers or buckets
Execution of direct rotary drilling with casings and casing oscillator
Continuous flight auger (CFA) and diaphragm walls
Execution of double head drilling
The HR 260 is available in the following two versions:
HR 260 CP: The standard version is equipped with a pull-down cylinder which exerts its force on the rotary allowing a rotary stroke of 6,100 mm (20 ft) approx. It is principally utilized for drilling large diameter bore holes. The HR 260 CP uses a parallelogram system of articulation guaranteeing a notable range or motion up to 1,000 mm (3.3 ft).
HR 260 THD: Available upon request, the THD system moves the rotary by utilizing a crowd winch, with a longer stroke of the rotary along the mast, 10,000 mm (33 ft) approx. The THD version is particularly useful for driving and extracting casing tubes directly by the rotary and, without a doubt, increasing your daily productivity.
on request with main bigger winch
The HR 260 is a self-erecting 75-tonne drilling rig for drilling large diameters both by the conventional kelly bar drilling system and by execution of direct rotary drilling with casing tubes and even use a casing oscillator as an optional. The HR 260 is able to perform the following applications:
Drilling large diameters and great depths with augers or buckets
Execution of direct rotary drilling with casings and casing oscillator
Continuous flight auger (CFA) and diaphragm walls
