A brief introduction of concrete pump truck with boom

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.
original imported GERMANY STEIBEL transfer case and REXROTH pump group;
original imported slewing reductor and slewing motor;
original imported GERMANY HAWE proportional multiway valve;
original imported GERMANY REXROTH valve and valve from ITALY oil-control companies;
electric control box adopting totally imported parts while control modules like PLC are all products from GERMANY SIEMENS.

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.

Radiator

Original imported ITALY EMMEGI hydraulic oil radiator.

Pumping system
F230 big-diameter transport cylinder can afford large pumping flow and good aggregate suctionability.

Hard alloy eyeglass plate and incising ring afford long life and handy maintenance.

Bucket
Big-capacity collecting bucket affords no dead angle and easy cleaning.

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. original imported GERMANY STEIBEL transfer case and REXROTH pump group are key parts of power switch,transmission driving and pumping operation. High-pressure water pump affords strong pressure and facilitates cleaning more.
electric control box adopting totally imported parts while control modules like PLC are all products from GERMANY SIEMENS. Self-lubricating system automatically injects lubricant into bucket and all positions of concrete cylinder which need lubricating through centralized distribution valve. Original imported GERMANY HAWE proportional multiway valve;
Original imported GERMANY REXROTH valve group Filter will first fiter hydraulic oil before the oil is sucked into hydraulic oil pump from oil tank Oil pollution indicator can precisely indicate the polluted degree of filter core to facilitate timely replacement.
Imported pollution degree tester ensures hydraulic particles¡¯pollution degree all above Nas7 and greatly improves hydraulic system¡¯s using life. Buckling hose¡¯s total equipment is produced by GERMANY HYDAC. Professional and advanced baking finish considerably prolong paint¡¯s using life.
GERMANY EMB connector and ITALY MANULI hose Cycle filtering trolley with 4 sets of high-precision filters ensures the hydraulic oil¡¯s cleanliness. On-the-spot pictures at building site
