Product Details
Hongda concrete pump truck is a product of Hongda Group's drawing on advanced experience at home and abroad, using modern advanced computer simulation technology to systematically analyze the impact of stress, displacement, natural frequency and other parameters changes on the pump truck structure on the fatigue life of the boom. At the same time, Optimize the design of the hydraulic system and adopt new free fluid technology to reduce the impact of pumping reversal on the boom. We have obtained a number of patents in the structural optimization of the pump truck boom and hydraulic system design to improve product quality control. , excellence in product manufacturing and meticulous quality inspection have made Hongda pump trucks reach domestic leading and internationally advanced levels. All steel plates in the boom system are made of high-strength cold-rolled steel plates from Swedish companies, with a yield strength above 100%, ensuring high strength of the boom system. , light weight, boom system boom, legs, fuel tank, etc. are subjected to post-weld stress relief treatment. Every weld of the rack system has been subjected to non-destructive flaw detection or photo-photography to eliminate any defects that hide any details, and the durability performance is even better
The slewing bearing of the boom system is made of products from Germany's Rotter Eide or Italy's Lario Lisa, made of 100% material, which has higher strength and service life
Accurate data support through finite element analysis and dynamic simulation analysis As the design basis, ensure that the boom system has a reasonable structure and excellent performance. The national testing center conducts stress and strain testing to verify that the boom structure calculation and analysis results are consistent with the actual working conditions. Hongda pump trucks adopt international procurement, and all key components are imported from international Well-known brand, has the following characteristics
Large diameter conveying cylinder, good material suction, large pumping flow rate
Original imported German infinite remote control device, light weight, easy to carry, only use the handle to control the cloth boom It can be accurately positioned
, the pumping volume can be adjusted steplessly
, the extension speed of the pump truck can be steplessly adjusted in fast and slow gears
, the boom rotation speed can be steplessly adjusted
, equipped with Emergency braking device, diesel engine automatic speed up and down device, saving fuel consumption
Original imported German transfer case and German Rexroth pump set
Original imported slewing reducer and slewing motor
Originally imported from Germany Wei proportion multi-way valve
Original imported valves from German Rexroth and Italian oil control companies
All imported components, electric control box, and other control modules are products of German Siemens
Hydraulic system features< br/> The free-flow closed hydraulic drive system formed by the confluence of two pumps has the characteristics of large output power, low loss, and smooth reversal without impact
The intelligent control system ensures that the driving oil flow is continuous and uninterrupted, and Directly input the drive cylinder work without loss
No need for cumbersome intermediate reversing control valve block, reducing reversing impact, avoiding excessive oil temperature, and making maintenance easier
With a huge oil tank Compared with the open system, the closed system requires a smaller fuel tank, and the oil in the tank flows gently and is not easy to emulsify. The unique buffer technology can reduce the high-pressure peak of the system. Even when the output is very high, the boom vibration is small. The tail pipe is stable
The electric proportional variable is adjusted so that the concrete output can be poured as needed
