| The Scraper is controlled from the tractor cockpit,
with the double effect remote controls that the tractor is fitted
with. Therefore, all standard machines are designed to performe their
movements through two double effect controls, the first governing
the lifting and lowering movements through the front articulated
cylinder (which can be also set for laser functioning) the second
for opening and closing the bulkhead. When controls reach their end
run position, they cause overpressure: oil flows
through a sequence valve to the back cylinder which in turn moves
the hatchback forward or backward according to need.
If a customer wishes to remove the sequence valve from the standard
version, then it is necessary to install three remote controls
to operate the machine three main movements.
The front articulated cylinder serves to perform the machine loading
operations: the blade cutting depth will be set according to the
nature of the soil and the power of the tractor.
At the same time, the other remote control allows to operate the
bulkhead, choosing the opening size which is most suitable to collect
the earth that is being cut by the blade.
Once the Scraper is loaded, the bulkhead is closed while the whole
machine is lifted to be transported. At the unloading site, the
amount of earth to be unloaded can be adjusted widening or reducing
the space between the blade and the ground; then the bulkhead is
opened, and the earth starts being dumped. When the bulkhead reaches
its maximum opening, the remote control button must not be released
until the machine is completely empty: the pressure of bulkhead
cylinders will be transmitted to the back cylinder operating the
hatchback, which will push the soil to the blade thus unloading
the machine completely.
After unloading is completed, the same remote control will operate
the machine in reverse order, closing the bulkhead tight and putting
the hatchback back into its normal position, ready to start a new
loading cycle.
