A five-tool player

It is powerful but not bulky, it is agile but does not lack in stability. HPM125 Standard is one of the machines favoured by our customers due to the compact dimension, the performance and the ease of setup. The perfect machine for any kind of needs, especially for drilling foundations, ratholes and landfills.


A five-tool player

HPM125 is the ideal machine for foundation, rathole and landfill drilling.
The compact dimension and the ease of setup, the HPM125 is a machine with very low operating and haulage cost.
It can be easily converted from standard to short mast configuration by simply replacing mast, pull down cylinders and kelly bar.

HPM125 is a strong, powerful drilling machine mounted on the new CAT 323 Narrow base and CAT expandable undercarriage. Equipped with a CAT C7.1 engine that meets U.S. EPA Tier 4 Final and EU Stage IV, together with the retractable undercarriage is the result of a machine with low operating cost and ease of transport.

Automatic functions like auto-verticalization of the mast, return to drilling point with one button, automatic rig-up from transport to working phase will ensure safety, reliability and high drilling performances.

Counterweight Lifting System

This HPM can be assembled by itself without the need of assistant cranes.

This patented feature gives contractors the ability to quickly and easily reduce the overall weight of the rig during the transport phase, making it possible to utilise a standard-sized trailer and reduce then hauling costs and avoids oversize/overweight permits.

Auxiliary House Lock

The operator can make the full use of the whole torque without having the machine swinging from side to side.

This patented feature can be automatic or enabled through a button on the joystick. The enabling of the brake offers increased comfort for the operator as the vibrations when drilling on rock are reduced to almost zero.

Low-headroom Configuration

This HPM can be quickly and safely converted in Short Mast configuration allowing it to work in limited heights job sites, such as under bridges or below power lines.

Comfort Cabin

The HPM cabin is equipped with a comfy and wide adjustable seat. The standard automatic air conditioning keeps the cabin at the ideal temperature throughout the day.

All machine interfaces are ergonomically positioned and designed for optimum control and efficiency. The easy accessible keyboards allow the operator to quickly get the rig ready to drill.

Automatic Functions

Automatic functions allow the operator to reduce rig-up time and get the most in productivity.
With a push of a button, the operator can make use of automatic functions, including: Verticality of the mast, Automatic Rig-up, Automatic return to drilling point and rotary auto drive.

Expandable Tracks

The retractable undercarriage allows to reduce width of the machine for transport phases, reducing hauling related costs and avoiding transport permits. Once expanded, the undercarriage provides great stability at any working radius for a 360° drilling capability.

Drilling Cruise Control

The HPM software includes the enabling of the drilling cruise control. When the system is enabled, the operator can preselect the rotary gear so it’s speed. With a push of a button the system can be activated and the operator can also lock the crowd pressure for a complete automatic drilling mode. Safety systems can disable the function immediately.

Remote Control

Increase safety and flexibility when loading or unloading the equipment. The operator can make use of different viewing angles while moving the machine from outside the cabin. Having a complete view of the rig during these phases allows the operator to make sure that hoses, wirings and wire ropes are safely positioned. Drilling functions are enabled through the remote control for a safe service and maintenance of the rig.
