FD60 – Hydromill

The Casagrande Hydromill FD60 is the model that suits the widest range of requests for special foundations. A version is available with special motors to increase the wheels torque. The hydromills are designed by Casagrande to match today’s demands of diaphragm wall construction

The equipment consists of a heavy steel frame with two drive gears, attached to its lower section, which rotate in opposite directions around horizontal axes. The soil, or rock, is “milled” by the cutting wheels from the bottom of the trench and continuously moved, mixed with slurry, and removed by a powerful fl ushing pump.

The hydromills utilizes a wealth of engineering expertise gained by Casagrande in many years of geotechnical available for the application of electronics to record depth, verticality and cutting force and to provide with instant information to control performance and maximize on production. The all-round ruggedness of hydromills are complemented by attention to details. The suspension of the hose reels by automatic winches and the fi tting of a powerful flushing pump to remove cuttings.

Whether in hard or soft soils, a choice of cutters is available to match every condition and demands of different wall width scan be easily met, simply by changing the cutter wheels and the interchangeable guides. All models of the hydromills are designed to work on the principle of reverse circulation. Cutting chains are used enable the equipment to cut through hard strata, to guarantee the cut throughout the wall width and to provide better joints and excellent interlocking.

Technical Innovation

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 hydraulic power system uses Full Load Sensing (FLS) technology. Unlike more common hydraulic management systems, the FLS system supplies only the required amount of oil requested by the functions thanks to the interaction between pumps and distributors. It allows optimal management of the power demands and reduces losses, achieving up to the 25% of fuel saving (calculated on the basis of a theoretical working cycle)

SAFETY & TECHNOLOGY

The canopy design of the B125XP offers maximum accessibility and safety for maintenance tasks: · Side door with automatic electro-hydraulic openings · Complete opening of the engine and winches compartment for maximum accessibility · Side folding ramps (as option) · The lifting sides become safety rails during maintenance activities on the upperstructure

FLEXIBILITY

The XP control system offers a number of advantages for the operator including: · Monitoring of all working functions and parameters, · Diagnostics of the working systems to ensure constant monitoring of the sensor and component status. · Easy conversion to any drilling arrangement using the control system: there is no need for manual intervention when changing drilling settings. · Customization of the working parameters. · Remote rig assistance, diagnostics, monitoring of the working parameters.
