The new MR-P 400 is a crawler piling rig for the execution of bored piles and CFA piles. The compact dimensions and the remarkable power of the MR-P 400 allow to realize bored piles up to 1200 mm (47.2 in) in diameter with max. depth of 27 m (88.5 ft), and CFA piles up to 750 mm (29,5 in) in diameter with a max. depth of 11 mt (36 ft).
The innovative hydraulic and electronic systems developed by Marini increase safety, performance, reliability and facility of use thanks to the new operator / machine interface.
Mainly suitable to work in restricted areas and LHR (Low Head Room) conditions thanks to the compact mast and articulation design that allows flexible positioning options.
Another novelty that the MR-P 400 brings is the presence of the renewed system of diagnostics and machine control from Marini named “M-TRONIC” is the new interface for the operator equipped with a high-definition touch screen, to keep an eye on all parameters and settings of the drilling rig.
