About
technical
optional

Casagrande’s new series of XP-2 in CFA Configuration 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 B400 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 467 kNm,the HD kelly bars and a powerful winch, the B400 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 600 kN and rotary head stroke of 21 m.

“Keep the operator happy in a comfortable working environment” is our formula for added productivity. The B400 XP-2 is designed to satisfy the strict European Union standards on safety and is manufactured to comply with the ISO 9001 requirements on quality.

PERFORMANCE AND PRODUCTIVITY

The Smart Power Management (SPM) is an intelligent engine power management system that improves performances and productivity of the machinery. The SPM system monitors the momentary power flows and immediately allocates the available power to the different jobs, so the operation function has always the maximum power available.

FULL LOAD SENSING TECHNOLOGY

The XP-2 hydraulic power system uses the Full Load Sensing (FLS) technology. Unlike the common hydraulic
managing systems, the FLS pressurizes only the required amount of oil requested by users thanks to the back-action between pumps and distributors. It allows to manage the power demands and reduces dissipations, achieving up to the 25% of fuel saving (calculated on the basis of a theoretical working cycle).

SAFETY & TECHNOLOGY

The B400 XP-2 has a very low sound emission level as a result of the of sound-absorbing materials and oil heat exchangers, designed for reducing the overall noise level. The layout of the machine and the wide openings of the canopy offer comfortable and easy access for inspection and maintenance. The machine conforms to the last international standards to guarantee the maximum safety of the operations.

FLEXIBILITY

The XP-2 control system offers the following advantages for the operator and the supervision of the work: monitoring of all working function, diagnostic of the working systems to ensure the constant monitoring of the status of sensors and components, easy conversion in any drilling arrangement, friendly customization of working functions e.g. mappings of torque and speed for EP rotary head, remote rigs assistance, diagnostic, monitoring of working parameters.
