Place of Origin:
38X-5RZ ZOOMLION 6X4
3.1.1 Chassis:This truck-mounted concrete pump adopts BENZ chassis.
3.1.2 Intelligent rotation buffer technology for boom
Introduce flexible control when boom is started, rotated and stoped, this reduces the impact and vibration for the boom ,which make the whole machine work more steady ,reliable and safe.
Boom,swivel head,swivel framework,base structure and outriggers consist boom system.
3.2.1 Wide placing range: the 38X-5RZ placing boom’s horizontal radius is 34m, and the maximum vertical reach is38m.
3.2.2 Light weight: strong rigidity Boom frame is made of high strength alloy steel, which designed with the newest structure. Thus the placing boom becomes less weight with better mechanics performance and much stronger rigidity.
3.2.3 More steady: equipped with slewing reducer, slewing bearing which with advanced technique in world and electro-hydraulic proportional direction valve, etc. All of these ensure the boom’s motion of slewing and extension more steady.
3.2.4 High reliability: electro-hydraulic proportional valves and compensation valve with secondary pressure relief valves are all original ones imported from Germany HAWE. This prevents boom going at excessive speed while it being folded back. And this also prevents boom being damaged in case of the increase of pressure in boom cylinders caused by outside force. So, the reliability of the whole machine is improved effectively.
3.3.1 The pumping unit optimize design by ZOOMLION: when the suction area and stroke have increased,it can make the suction efficiency achieve to over 80% of the academic numerical value and higher 10%-15% than trade.
