Concessions must also be made for various
winter oils regarding the pressure load and
wear protection.
Please ask your supplier about the measures
required when using its oil.
We recommend using a hydraulic oil from the
same supplier and same series, as it was filled
in for "summer operation". In these cases,
lower quality losses are generally to be
expected. However, residual oil in the system
causes the viscosity range to shift.
Should series or manufacturer be changed,
flushing with the new type of oil is required.
Thereby switching all valves several times.
Fully extend and retract all cylinders.
At temperatures below freezing point, there is
the possibility to warm the hydraulic oil using
the sturdier gear pump of the agitator circuit.
- In addition, close the ball valve 1 (Fig.: 3) on
the agitator motor.
The hydraulic oil is then routed to the tank via
the pressure relief valve and thereby warms up
faster.
The temperature of the hydraulic oil (optimal
operating viscosity) can be found in vector
control.
If the optimum hydraulic oil temperature is
reached according to diagram (Fig.: 2), reopen
the ball valve.
1.5 AIR SYSTEM
Due to its constructions, piston compressors
may not be commissioned at ambient
temperatures under +1° C (risk of damage
caused by frozen water).
Rotation compressors are usable up to -15° C,
with appropriate maintenance.
Since the vehicle air system provides the
electro-pneumatic pilot control for some truck-
mounted concrete pumps, it is, therefore, also
important to set the vehicle air system to winter
operation.
Vehicle air systems are equipped with air
dryers or frost guards to prevent condensation
water or keep water from freezing.
1.6 GEAR
A gear oil change is only required at
continuous temperatures below -10° C.
It is also possible to use a multi-purpose oil.
