Berthoud Raptor self-propelled sprayers, developed by Berthoud specialists in France, were presented at the Innovagri show in September 2008 near Paris.
The company's engineers successfully combined the features of the earlier Boxer self-propelled model with new elements of the Tenor trailed sprayer in a machine with impressive design and capabilities.
The high-clearance design of the Berthoud Raptor self-propelled sprayers (1.8 m) with a smooth underside includes active air suspension on both the front and rear axles, guaranteeing high stability. Exceptional manoeuvrability comes from the triangular articulated design of the rear oscillating axle.
The spacious air-conditioned cab gives the operator good visibility and comfort, and the rear-mounted sliding entry door keeps dust and noise out of the sealed cab. An air-suspended seat provides operator comfort.
The twin-section Omega centrifugal pump with an output of 550 l/min needs virtually no maintenance. It is included as standard.
Outlet and drain pipes at the bottom of the diamond-shaped main tank reduce chemical residues after spraying. Lockers for protective clothing, containers and tools, as well as the induction hopper, are hidden behind hinged side panels.
Models are available with 3,200 l, 4,200 l and 5,200 l tanks and booms from 24 m (Axiale) to 42 m (Ektar). Power comes from 6-cylinder Deutz engines of 200–270 hp with Common Rail injection and Tier 3a emissions. There are two working speed ranges plus a transport range of up to 40 km/h! Two Rexroth hydrostatic pumps drive four hydraulic motors built into the wheels. HydroPilot cruise control is standard. The operator can steer two or four wheels and also has so-called «crab» steering.
valve for adjusting suspension air pressure according to load;
hydraulic shock absorbers on each wheel to limit unwanted oscillation.
differential locks as standard;
high-speed variable-displacement motors: flexibility and adaptability;
HYDROPILOT cruise control as standard;
3 speed ranges: 0-18 km/h - 0-25 km/h - 0-40 km/h;
motors built into the wheel legs.
AXIALE boom – legendary stabilisation
Perfect boom stabilisation at high speed and in turns, on difficult uneven terrain, on hills and slopes.
The boom pivot is at the boom’s centre of mass. In operation the boom always stays horizontal, parallel to the ground surface. Truss design along the entire boom length. The nozzles are protected by the truss structure. Boom stabilisation can be adjusted by tensioning the springs (only on BERTHOUD). A breakaway joint at the boom tip works in 3 planes.
The boom is at the rear. Less oscillation. The cab stays clean. Operator health protection. Better visibility. The boom, engine and tank are balanced so that the centre of gravity is in the middle of the sprayer.
Available in working widths from 24 to 33 m.
OMEGA pump
Centrifugal twin-turbine pump – a double centrifugal effect. A genuine output of 550 l/min at a working pressure of 3 bar (with spraying and agitation on). Maximum pressure up to 8 bar. The cast-iron housing means greater corrosion resistance and the ability to apply UAN.
DUNLOP air suspension:
BOSCH REXROTH hydrostatic drive:
2 pumps, each responsible for a separate axle. The hydrostatic drive takes up little space and the underside is completely smooth. Large hydraulic motors deliver high power at low pressure. The hoses are protected by a metal cover.
EC TRONIC computer. Fast response, full valve rotation in less than 3 sec. Easy to use. Three programming levels (protection against accidental errors). Works with precision farming systems from Trimble, TeeJet, N-Sensor, Satplan and others.
One monitor for all chassis parameters: Engine speed, working speed, gear, fuel level, tilt angle, drive mode, track width, ground clearance, etc.
Engine:
– RAPTOR models are fitted with DEUTZ engines meeting TIER 3A emission standards. Engine power for the different models is 200-270 hp.
– New ECO MOD engine mode. New optimised speed control = efficient fuel use. When ECO mode is selected on the panel, the engine chooses the optimum setting for the situation (each time the speed changes): optimum torque, engine speed and hydraulic oil flow for the transmission.
Example. When spraying on flat ground, engine speed can drop to 1,200 rpm. Engine speed adapts automatically, smoothly and precisely between 1,200 and 1,900 rpm.
Rear-mounted boom. Less oscillation. The cab stays clean. Safer for the operator’s health. Better visibility while driving. With a front boom, herbicides stay on the wheels. The boom, engine and tank are balanced so that the centre of gravity is in the middle of the sprayer. The cab sits behind the front wheels rather than above them – operator comfort thanks to better cushioning, and a better forward view along the rows.
