Power unit 3 is filled on this smaller in power type selecting；The third, high capacity, huge discharge pumping operating mode (are mainly built including height
Build pumping construction), chassis power unit 1 is difficult to meet construction power demand, now upper dress power unit 3 and chassis power unit
1 works simultaneously, and chassis power unit 1 and upper dress power unit 3 drive respective oil pump, the first oil pump 4 and the 4th oil pump simultaneously
Main system 14 and oscillator system 13 are acted on behind 63 interflow, it is common to drive pumping mechanism 8 to work, now, upper dress 3 need of power unit
Part power of the construction power demand peak value higher than the maximum output power of chassis power unit 1, therefore upper dress power are provided
Unit 3 is operated alone the high power of the work of pumping mechanism 8 without the need for providing, therefore can be less in power type selecting, and this
Mode of operation is relatively reasonable in power utilization, it is to avoid the phenomenon of " low load with strong power ", and energy-conservation is obvious.In addition, above-mentioned enforcement
The upper dress power unit 3 mentioned in example can also be provided separately power for low-rise building construction, now because construction height is relatively low,
Power demand is little, as long as upper dress power unit 3 meets demand；Preferably, the rated power of upper dress power unit 3 is less than
The output of the 4th oil pump 63, now can be achieved with reducing the purpose of energy consumption, it is, of course, also possible to according to actual condition, according to
Construction experience, is that upper dress power unit 3 selects a rational dynamic range so that energy-conservation becomes apparent from.
