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.
3.2 Boom system
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 Pumping system
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.
