WORKING DEPTH
CONSTANT WORKING DEPTH WITH SOFT CONTROL
The HELIOS can be equipped either with spring or hydraulic “Soft control” pressure overload protection to ensure a constant working depth over the entire width.
Perfect working depth
With the hydraulic “soft control” system, the star wheel elements are provided with the same oil pressure on the entire width. Hydraulic linkage between cylinders. This results in a constant working depth over the entire width of the HELIOS, independent of the surface. Each element maintains the same ground pressure. Additional pressure can be adjusted on the star wheels. With the mechanical version each arm is independent equipped with an infinitely adjustable mechanical spring system. The ground pressure setting (penetration force) is adjustable by tightening a nut on each element.
