Useful drilling depth equal to 18 meters, like the stroke of the rotary, which can become 24 meters. through the use of a rear truss fixed directly on the mast, combined with a through spindle installed on the same rotary. Mast equipped with a device for supporting and tensioning the hydraulic pipes and for transporting drilling fluids to prevent them from resting on the ground, without ever interfering with translation and drilling operations. Remarkable qualities of high maneuverability, reliability and productivity, even in case of use in extremely severe conditions, all thanks to the adoption of numerous innovative technical solutions and an accurate sizing of all structural parts. Active and passive protection devices always guarantee maximum safety conditions for the operator and for any other people working on the machine. peculiarity, versatility and power • Drilling tower designed to have a very high structural stiffness to prevent bending effects of the tower itself due to its own weight. • Articulation groups of innovative conception that allow, by means of hydraulic jacks connected to a mechanical device with levers, a continuous rotation of over 180 degrees of the telescopic columns supporting and positioning the drilling tower. The telescopic columns between them can be positioned for perforations inclined with respect to the vertical axis of 30 ° and 30 ° with respect to the horizontal axis. To increase the horizontal drilling height by 2100 mm, two counter skids are installed under the telescopic rods. • Tracked undercarriage equipped with a fifth wheel that allows the positioner to be rotated by 95 degrees parallel to the excavation face, to facilitate positioning within the same drilling face. • Electric remote control or, if required, radio control of all movement and work functions to always guarantee conditions of maximum safety while maintaining maximum productivity and operating reliability. • Automatic power distribution system with "Load Sensing" main hydraulic pump to optimize the performance of the drilling rig to maintain very high machining productivity. • Hydraulic crane with 7.5 ton capacity and max extension. 11mt. The operator can operate on the crane via radio remote control directly from the basket or directly from the ground. • Adoption of automatic devices that make it easier to use the machine even by less experienced personnel. • Generous oversizing of the structural parts that takes into account critical conditions generated by any errors by the operator himself. • Double hydraulic system, the first running with an electric motor, the second with a diesel engine equipped with a diesel particulate filter at the exhaust. The adoption of a 200 hp diesel engine and a 132kW (180 hp) electric motor make available an exceptional power that allows you to reach unparalleled levels of productivity. • Rotary wheels with max. Torque are applicable. up to 32000 Nm, with high specific power that allows simultaneous operation with high torque values and rotation speed even in the case of external hammer + rotary application. • Device for inserting fiberglass elements. • Device for inserting reinforcement pipes. • Automatic system for the extraction of the lining tubes. • Laser for alignment of the drilling axis. The drilling rig complies with CE standards, specifically UNI EN 791. Technical characteristics subject to modifications without notice. The worldwide diffusion of the product illustrated here requires, due to the different regulations, the use of images and illustrations that are purely indicative, therefore not binding.
