HYDRAULIC SIDE OFFSET (GRADER)
It is useful in case of having to shift the material sideways (to the right or to the left) as to the advance sense of the machine.
CENTRAL FULCRUM TROLLEY
It allows to execute transversal slopes on the right and on the left (in case the area to be levelled is not wide enough) by lifting the blade on the desired side and thus getting to have a sloping plain as to the horizontal plain. This way of operating guarantees the best precision during the work.
With manual control
=> the blade gets to be lifted on one side and on the other one (graduated reference mast with central "0").
With dual mast and dual receiving system
=> the slope is set by means of a quota (mm)
=> it is used to level sidewalks, tracks etc.
With slope sensor
=> the slope is set by means of a percentage (degrees)
=> it is used to level roads etc.
It is operated with manual control and it allows to lift one side of the blade, so that you can level correctly near the embankments and in the corners of the fields.
When the ram is at the end of the stroke and it is completely closed, the blade is parallel to the trolley.
