The Casagrande B275XP-2 is a multifunctional machine designed to drill large and small diameter boreholes, insert and extract long casings, to power a casing oscillator, to pile in continuous flight auger method and is also ready for conversion into diaphragm wall equipment.
"The B275XP-2 is designed to work on the most challenging sites due to its highly specialised technical characteristics including 270kN high speed winches, the new H30 rotary head with a maximum torque output of 300kNm and speeds of up to 29rpm.
The engine is controlled by a Smart Power Management (SPM) system that improved performance and productivity of the machinery by allocating maximum available power to the operation function.
The Smart Power Management (SPM) is an intelligent engine power management system that improves performances and productivity of the machinery.
The hydraulic and electronic systems on the XP-2 series are able to directly control the performance of the hydraulic pumps in order to achieve efficient, precise and rapid execution of all operations. The powerful diesel engine uses a highly efficient coupler to transmit the required power to the latest generation of hyraulic pumps whilst ensuring reduced pollution emissions and minimum fuel consumption.
The B275 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.
The XP 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 functions thanks to the back-action between pumps and distributors. It allows for management of the power demands and reduces dissipation: achieving up to the 25% of fuel saving (calculated on the basis of a theoretical working cycle).
The XP control system offers the following advantages for the operator and supervisor: 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.
