MDT 60 B
The MDT 60 B is a powerful and very compact drill rig, developed especially for heavy site works, offers exceptional manoeuvrability, reliability and productivity, thanks to the adoption of many innovative technical solutions.
The MDT 60 B rig was made for satisfying numerous demands in search of the right equipment that would permit to implement different works in reduced space conditions.
So it became possible to carry out micropiles, tie rods and consolidation rods, by using jet grouting technologies as well.

High extraction force that is not affected by any reduction in cue-lift thanks to the hydraulic piston.
Mast vertical axis rotation system to drill in parallel position to the crawlers.
Portable electric remote-control desk, that guarantees the maximum safety condition and comfort to the operator, during placement, working phases and moving; in particular when climbing and drifting down from the transport carriage on the road.
Automatic power division system in order to improve the rig’s performance and maintain the productivity at a high level.
Automatic devices’ application makes easier the use of the rig itself also by less experienced personnel.
Ample oversizing of structural parts taking in consideration possible critical conditions due to eventual operator’s mistakes.
The drilling machine meets the CE norms, especially the UNI EN 791.

Even though the dimensions remain reduced, the possibility to install the engine of 102 hp with exceptional capacity permits to reach unequalled productivity levels.
For high performance the rotary may be applied, with torque max. up to 14000 Nm, without decreasing significantly the rotation speed.

The articulation is based on parallelogram with mast lateral positioning system. Mast rotation is moved by two independent hydraulic cylinders equipped with control valves, it is possible to achieve a continuous mast rotation equal to 91,5° for each side to achieve an overall mast rotation equal to 183°.
A lateral swing allows positioning of the hole centre out of the track increasing a versatility of the drilling unit. Mast vertical axis rotation system to
drill in parallel position to the crawlers allows to execute drilling works near the walls with the minimum crawler truck’s movement.
The substantial rigidity of the structure and of the joints, allows a precise positioning of the mast in addition to the drastic reduction of undesired movements due to the stresses during use rotary trolley speed and thrust force can be controlled independently.
The mast, made of high yield point steel, is equipped with lateral guides made of special steel for the rotary head trolley sliding and for longitudinal movement of the mast itself allows as well a quick installation of the necessary accessories for grouting jetting.
Hydraulic piston, installed inside, activates the jack chain of the rotary trolley developing maximum extraction force equal to 7 T.
The trolley is equipped with a piston for the lateral displacement of rotary, letting free the borehole axis for the reinforcement insertion.
