Massenza Drilling Rigs has just delivered two MI12 in Asia. The rigs, mounted on a 6x4 heavy duty trucks, have reached an important coal mine and have already started to performing mineral researches for the new mining area.
The solid construction and the high quality materials and components of the rigs guarantee to the client reliability, high productivity and security, key points of all Massenza equipment.
With a 8 speeds coring rotary head, a 10,2 Tons pull-back, a powerful duplex mud pump and the wireline mounted on the mast, the new MI12 are able to drill, fast and easily, up to 580 m with HQ rods.
Thanks to a special mast support, the rigs can also drill in 45° position, allowing flexibility of operations and movements in the mining job site.
The new Massenza CORING ROTARY HEAD, thanks to its strong construction and the most innovative technological solutions, has 8 speeds and can reach a maximum torque 10.484 Nm and a maximum speed of 1.200 RPM, giving to the driller full flexibility.
Due to the high speeds it can reach, this rotary head can also perform diamond coring and the HYDRAULIC CHUCK, with BQ-NQ-HQ-PQ jaws and 12 Tons blocking capacity, speeds up the operations and increase a lot the productivity of the equipment.
