A brief introduction of Hongda series concrete pump with boom
Bringing in advanced experience both at home and abroad, HONGDA concrete pump with boom is developed by applying modern advanced computer simulation techniques and systematically analyzing the influence condition of the boom fatigue life because of the change of various parameters such as stress, displacement, natural frequency etc. The series products won many patents on boom structures optimization and hydraulic systems design.
Perfect product quality control, perfect product making, and absolutely adequate quality inspection make HONGDA pump truck achieve Chinas leading level and international advanced level.
---Pump system adopts steel plates all from Swedish SSAB, which have been treated by high-strength cold rolling with yield strength beyond 900Mpa, to ensure boom system with high-strength and light weight. The systems aggregate carrying pipe, landing leg, and oil tanker, etc. all have been treated by 100% stress 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 capability. Stress and strain test are conducted by national test center to verify the coherence between boom structures calculated analysis result and actual working condition.
HONGDA concrete pump with boom adopts international purchasing for the key parts all from international famous brand:
---Original imported Germany HBC wireless remote-control device with light weight and handy carrying enable aggregate carrying pipe to take position accurately simply by manual control. Pumping capacity can be infinitely variably controlled. Boom expanding speed can be infinitely controlled through quicken-slow device. Boom slewing speed can be infinitely controlled.
---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 close hydraulic driving system formed by double merging pump 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 leading to the maintenance easier.
---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 systems 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.
