2. HIGH AMBIENT
TEMPERATURES
2.1 GENERAL
In principle, it is useful to "keep an eye" on the
temperatures of the pumping line, individual
aggregates and fluids at high ambient
temperatures.
It is also possible to place the machine such as
to protect it from direct sunlight.
Machine and pumping line should be painted
brightly.
Relocate separate pumping lines preferably in
the shade, cover, if necessary.
Make sure that the VECTOR control of our
truck-mounted concrete pump monitors the
hydraulic oil temperature and reduces the
power of the concrete pump as of +85° C. The
concrete pump switches off at +95° C.
Furthermore, the temperatures of the motor
coolant and compressors can also be
monitored.
This monitoring can also be combined with a
switch off function.
It is, therefore, useful to ensure optimum
cooling:
- Fill all the oils, as well as the coolant up to the
max. marking.
INFORMATION
Do not fill too much! Liquid expands during
heat and the reservoirs overflow.
- Keep the slats of the motor- And hydraulic
fluid clean.
Clean more often with high dust
accumulation.
- Change the insert of the motor air filter, if
necessary.
- Do not open the maintenance flaps in order to
improve the cooling effect.
This could interfere with the air circulation
and have the opposite effect.
- Ensure correct adjustment of the hydraulic
system. For example, a too low setting of a
pressure relief valve will cause the oil
temperature to increase because oil is
continuously discharged under high pressure
through a small cross-section.
- Replace the water in the water box with fresh
water when it warms up excessively.
- Sprinkle the differential cylinders of the
concrete pump with a water hose.
INFORMATION
Do not spray water onto the hydraulic oil box.
This would cause strong water condensation in
the box.
- Do not feed with maximum stroke rate.
High stroke rates increase the temperature of
the hydraulic system and are extremely
pointless for stiff concrete, as they are then
sucked in poorly.
CAUTION
Sucking in air increases the risk of an
accident caused by a troubled boom and
pounding of the end hose!
Reduce the stroke rate and make sure that
the filling hopper is always filled by 2/3.
- Run the system in idle during pumping
breaks.
This will continue pumping the hydraulic oil
through the radiator, and the motor oil
transporting the heat away from the hot turbo
charger.
