Frame
Designed to overcome the limitations associated with high speeds on the road and in the field, the ALPHA chassis achieves the maximum working comfort.
The chassis is made of high tensile steel (DOMEX® Swedish steel) and consists of U-shaped beams with riveted cross-members to offer lightness and flexibility.
The position of the main components (engine, main tank, rinsing tank, tanks, pump etc.) has been specially studied to optimize the weight distribution between the front and rear axles, which guarantees the best driveability and preserves the soil structure.
All the variable loads are situated at the centre of the machine.
Spring suspension
Simplicity and reliability are maintained with the HARDI suspension principle, which offers a very natural and optimal movement over obstacles. It allows an excellent follow-up of the ground for optimum traction and increases the operator’s comfort.
This mounting is a great benefit, limiting the strain on the chassis and increasing the longevity.
The front axle works with two helical springs, while in the rear a helical spring with an adjustable shock absorber is built in at the centre of the chassis. Due to its anti-roll design the rear axle movements do not disrupt the stability of the boom.
(Coil suspension is only available for ALPHA 3500 & 4100)
FloatRide suspension
By equipping the ALPHA with the optional FloatRide, the standard coil spring suspension is replaced by airbags. This ensures even more boom stability and maintains balance of the ALPHA in strong slope. The chassis’ height will be maintained whatever tank volume.
By allowing for individual wheel movement, the ALPHA provides a maximum comfort, even at high spraying speeds through a wheel travel of 185 mm.
(Basis on ALPHA 5100 – Optional on ALPHA EcoDrive 3500 and 4100)
Hydraulic track width Adjustment
The ALPHA evo EcoDrive with FloatRide suspension can be equipped with Hydraulic Track width Adjustment. This Hydraulic Track width Adjustment axle allows a track width from 180 to 280 cm or from 210 to 320 cm (depending on tire dimensions).
The driver will set his track width from the cab display and will be ready to drive in no time. This will allow changing track width from the road to the field and from cereal crop to maize, row crop or vegetable with a variation of 1 m between minimum and maximum.
Steering systems
Four-wheel drive / two- and four-wheel steering
The three different steering systems make the ALPHA evo versatile in operation. On the road you drive as usual with the front axle steering, whereas during spraying operation the advantages of the all-wheel steering or the manual crab movement steering is used.
In four-wheel steering the turning radius measured in the middle of the machine is only 462 cm, which is extremely small. This ensures a maximum manoeuvrability, even in small fields, and in addition increases the area output. On the other hand, on slopes, the use of the manual crab movement steering allows, for example, to steer against the rear wheels to stabilize the track following.
Turning radius
Due to the small tyre and bracket dimension of only 56 cm, the narrow turning radius and a 100 % alignment of the wheels, the crop damage is reduced to the absolute minimum.
The turning radius with four-wheel steering and 2 m track width is only 462 cm measured in the middle of the chassis.
Four-wheel steering is possible with boom folded in.
The wheel base of the ALPHA evo is 375 cm. This ensures a stable machine when driving, also in rough terrain.
Superb surface treatment
The high-technology surface treatment contains 13 treatments, including a pre-treatment and powder coat painting of all major components.
Together with the Delta/Magni treatment of nuts, bolts and other items, we supply high corrosion protection of our products.
