Description
Big-diameter transport cylinder can afford large pumping flow and good aggregate suctionability.
1.Original imported GERMANY HBC wireless remote-control device with light weight and handy carrying can enable aggregate carrying pipe to take position accurately simply by manual control.
2.pumping capacity can be infinitely variably controled.
pump truck expanding speed can be infinitely controled through quicken-slow device.
3.boom slewing speed can be infinitely controled .
4.it’s 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 closed hydraulic driving system formed by double pump confluency 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 simultaneously facilitates servicing.
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 system’s 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.
