The hydraulic system
4.6.1 Using the hydraulic system tilting the load-carrying body
The hydraulic mechanism is used for automatic unloading of the Trailer by tilting the
load-carrying body backwards or to the sides. The hydraulic system of the tilting mechanism
is supplied with oil from the tractor's hydraulic system.
The hydraulic system consists of a plug for the coupling valve, hydraulic hoses, a
single-acting hydraulic cylinder, and a shut-off valve, as well as fastening and fixing
components. A valve block in the tractor's hydraulic system is used to control the raising and
lowering of the Trailer's body.
CAUTION
CAUTION!
Check that the oil in the Trailer's hydraulic system and the oil in the
tractor's external hydraulic system are of the same type and grade.
The use of different oil grades is not permitted.
CAUTION
CAUTION!
Hydraulic oil can heat up to high temperatures during operation.
The Trailer's hydraulic system Trailer must be completely leak-proof. The tightness of
the hydraulic system must be checked with several-seconds of overloading the system by
tilting the load-carrying platform to the rear. Tighten the couplings if there is an oil leakage in
the hydraulic hose lines. If this does not remove the fault, the line or coupling elements must
be replaced with new ones. If there is an oil leakage outside the coupling, replace the leaking
components in the hydraulic system. Any mechanical damage to the component necessitates
its replacement with a new one.
The condition of the hydraulic system should be monitored on an ongoing basis while
the Trailer is in use. When connecting the Trailer's and tractor's hydraulic systems, observe
the required cleanness of the connectors.
CAUTION
CAUTION!
Inspect the hydraulic system on a regular basis, every 6 months.
Check the condition of the hydraulic lines.
Replace the hydraulic hoses every 5 years, even if undamaged.
