Casagrande’s new series of XP-2 hydraulic piling rigs are designed and built using the latest state-of the-art techniques. A range of machines engineered to satisfy the needs of the most demanding contractor with emphasis on performance, reliability and economy.
The Casagrande B420 XP-2 is a multifunction machine designed to drill boreholes, to insert and extract casings, to power a casing oscillator, for piling by the continuous flight auger method and ready for conversion in diaphragm wall equipment.
Due to the high torque of the rotary head of up to 470 kNm, the HD kelly bars and a powerful winch, the B420 XP-2 can rapidly drill deep and large piles in hard soils. The crowd winch will drive casings deep into the ground with extreme accuracy having a line pull of 690 kN and rotary head stroke of 26 m.
“Keep the operator happy in a comfortable working environment” is our formula for added productivity. The B420 XP-2 is designed to satisfy the severe European Union standards on safety and is manufactured to comply with the ISO 9001 requirements on quality.
