The HR 260 is a self erecting, 75 ton drilling rig particularly suitable for drilling great diameters using the kelly bar system and with casing tubes directly with the rotary. 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) & 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 it’s force on the rotary, and is principally utilized for drilling large diameter bore holes. The rotary is able to work with a stroke of 6.100 mm (20 ft) approx. The HR 260 CP uses a parallelogram system of articulation guaranteeing a notable range or motion 1.000 mm (3.3 ft).
HR 260 THD – available upon request, The THD system moves the rotary by utilizing a crowd winch, allowing the rotary to be used along a larger stroke of the mast, 10 m (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.
The HR 165 is a multipurpose compact drilling rig, projected to realize several drilling techniques and suitable for medium to large diameter drilled shafts in any kind of soil by using a rotary system with Kelly bar, augers and bucket.
This model of hydraulic rig combine the high quality and reliability from MAIT experience with a design with renewed line. The cabin has been designed to offer maximum efficiency and comfort for the operator and equipped with air conditioning and heating system. The HR 165 comes with graphic interface on a LCD display that permits to control functional parameter in a easy and direct way and to manage some electronically controlled operations.
The HR 165 is mounted on widening crawler track and does not require disassembling for transporting making faster the displacement from job to job.
The MC 45 has been designed to guarantee better productivity for drilling of small and medium diameter bored piles, with maximum running economy. Thanks to it’s compact size, the MC 45 is easyily transported with no need to remove the kelly bar. This significantly allows the customer to reduce transport costs & set-up time, therefore increasing productivity on the jobsite.
