•
The operating temperature of the oil
in the system is between 35 - 55°C.
•
The minimum operating tempera-
ture is -23°C while the maximum op-
erating temperature is 82°C.
Hydraulic Oil
•
Mineral based hydraulic oil should
be used in the system and it should
be replaced every 6 months.
•
The viscosity of the hydraulic oil in
the system should be 12 to 100 cSt
(mm²/s). The ideal viscosity is 20 to
40 cSt.
•
Low viscosity hydraulic oil should be
preferred in cold weather and high
viscosity hydraulic oil should be pre-
ferred in hot weather.
Filtering
•
The system must be equipped with
an oil and an air filter. The oil filter
should not be used on the pump
suction line but on the tank return or
pressure line.
•
The most efficient filtering is 10 µm.
Filtering up to 25 µm is allowed.
•
The filters should be checked and
serviced periodically.
Issues
to
be
Considered
for
Installation
•
The cylinder should be painted after
the stage pipes are well covered.
When paint adheres to the stage
pipes, the paint residues deform the
cylinder seals after drying and
cause oil leaks.
•
The brackets must be mounted on a
flat and strong surface.
•
It should be ensured that the cylin-
der and bracket connection planes
are perpendicular. Because the cyl-
inder does not work properly when
tightened; stage misalignment and
deformation of the pipe and oil leak-
age occur over time.
•
It should be mounted according to
the space that will allow the mov-
able joints to adjust themselves ac-
cording to the load and the ground.
It should be noted that the connec-
tions are made not tightly, but by
leaving a gap.
•
The closed length of the cylinder
after mounting to the tipper or trailer
must be minimum 20 mm and maxi-
mum 50 mm more than the closed
length before the cylinder is
mounted.
•
When the stages of the cylinder are
opened, care should be taken to
leave a safe distance so that the last
stages do not touch the casing.
Points to Note When Operating the
Cylinder
•
The vehicle must be on a smooth
and strong ground.
•
The vehicle should not be moved
with the tipper open.
•
The driver should not leave the ve-
hicle while it is operating.
•
The operations should be carried
out at a location with sufficient light.
•
It should be checked before unload-
ing that the rear doors are open.
•
The flowability of the load should be
checked; stable loads might give
significant damage to the system
and the vehicle.
•
No persons should be present in the
vicinity of the tipper during operation
of the cylinder. Any tripping might
result in serious and fatal injuries.
