Hydraulic system features:
Free flowing closed hydraulic driving
system formed by double pump confluency has such advantages as large output
power with small wearing, and smooth reversal with no impact.
Intelligent
control system makes driving oil flow incessantly and directly enter driving oil
cylinder without any loss.
No fussy middle reversal control valve piece
lessens reversal impact, avoids too high oil temperature and simultaneously
facilitates servicing.
Compared with large-oil-tank open system, closed
system needs a smaller tank and the tank oil liquid flows gently with no easy
emulsifying;
Unique buffer technology can lower the system`s high-pressure
peak value. In spite of high-output-flow situation, the aggregate carrying pipe
vibrates little with the tail pipe steady. Electric proportional variable
adjustment makes concrete output flow pour according to actual needs.
HONGDA concrete pump truck is developed by applying modern advanced computer
simulation techniques and systematically analyzing what effect the change of
such various parameters as stress,displacement,natural frequency,etc. pump truck
structure receives has on boom`s fatigue life on HONGDA GROUP`s drawing on
advanced experience both at home and abroad. Meantime, the group optimized
hydraulic system`s design,adopted latest free fluid technique,greatly lessened
pumping reversal`s impact on boom,and won many patents on pump truck boom
structure`s optimization and hydraulic system`s design. Perfect product quality
control,perfect product making,and absolutely adequate quality inspection make
HONGDA pump truck achieve CHINA`s leading level and international advanced
level. Pump system adopts steel plates all from SWEDISH SSAB, which have been
treated by high-strength coldrolling with yield strength beyond 900Mpa, to
ensure boom system with high-strength and light weight. The system`s aggregate
carrying pipe,landing leg,and oil tank,etc. all have been treated by 100% stess
removing after welding. Every welding seam has been treated by 100%
nondestructive evaluation or X radial check to avoid any tiny defect and to make
the machine more enduring.
The boom system adopts slewing bearing from
GERMANY ROTHE ERDE or imported ITALY product, which have higher strength and
longer using life with texture to be 42CrMo.
Accurate data support from
finite element analysis and dynamics simulation analysis act as design basis to
ensure boom system with a scientific structure and excellent property. Stess and
strain test are conducted by national test center to verify the agreement
between boom structure calculated analysis result and actual working
condition.
HONGDA pump truck adopts international buying with key parts
all from international famous brand which have the following
features:
Big-diameter transport cylinder can afford large pumping flow
and good aggregate suctionability.
1.Original imported GERMANY HBC wireless
remote-control device with light weight and handy carrying can enable aggregate
carrying pipe to take position accurately simply by manual control.
2.pumping
capacity can be infinitely variably controled.
pump truck expanding speed can
be infinitely controled through quicken-slow device.
3.boom slewing speed can
be infinitely controled .
4.it`s equipped with emergency brake device and
diesel engine auto-control-speed device to lower oil-consumption.
