The Hongda Truck-mounted Concrete Pump with Boom is developed by Hongda Group on the basis of drawing on advanced domestic and foreign experience and using advanced modern computer simulation techniques to systematically analyze the effect of changes in various parameters like stress, displacement and natural frequency on the boom's fatigue life. Meantime, Hongda Group optimized the design of the hydraulic system, adopted the latest free fluid technique and greatly lessened the impact of pumping commutation on the distributing boom. In the boom structure optimization and the hydraulic system design, Hongda Group has obtained many patents.
We can supply you truck-mounted concrete pump with booms as below:
1. Truck-mounted concrete pump 37 m
2. Truck-mounted concrete pump 42 m
3. Truck-mounted concrete pump 45 m
4. Truck-mounted concrete pump 48 m
5. Truck-mounted concrete pump 52 m

With Chinese HOWO truck chassis or Imported Japan ISUZU truck chassis, all with EUROIII standard engine.
The design of HONGDA Pump Truck adopts an international purchase strategy, and all its key components are world-famous brands which have the following features:
The big-diameter conveying cylinder has a strong suction ability and can afford large pumping flow.
The HBC wireless remote-control unit imported with original German packaging is light in weight and easy to carry. The operator can put the distributing boom in place simply by operating the handle bars.
The pumping capacity can be regulated through the stepless control device.
The stretching speed of the distributing boom can be regulated through the quick-and-slow stepless control device.
The slewing speed of the boom can be regulated through the stepless control device.
It is equipped with the emergency brake device and the automatic speed-control device for the diesel engine to reduce oil consumption.
Equipped with the STEIBEL transfer case and the REXROTH pump unit imported with original German packaging;
Equipped with slewing reducers and motors imported with original packaging;
Equipped with HAWE proportional multi-way valves imported with original German packaging;
Equipped with originally-imported REXROTH valves and valves made by Italian oil-control companies;
It is equipped with an electric cabinet with totally-imported components; Control modules like PLC are all products from the German company SIEMENS.
Features of the Hydraulic System:

The closed free fluid power system formed by double pump confluence has the features of large output, small depreciation and smooth commutation with no impact.
The intelligent control system makes the driving oil flow incessantly and directly into the driving oil cylinder without any loss.
As there are no fussy middle commutation control valves, the commutation impact is reduced and excessively high oil temperature is avoided. Meanwhile, it makes maintenance easier.
Compared with the open system with a large oil tank, the closed system needs a small oil tank. The oil in the tank flows gently, which reduces the chance of emulsification.
The unique buffering technology can lower the system's high-pressure peak value. Even at the time of high output, the distributing boom vibrates little and the tail pipe remains stable.
