Excavators price ratio analysis. In general, a simple comparison of fuel from the device, imported machine-made machine than the fuel-efficient, fuel-efficient aircraft original machine than the joint venture, the Japanese fuel-efficient aircraft than European and American systems. 60 Similarly Shanghai Komatsu excavator from Europe and America in general terms of engine power lines prevail. Now made little digging Department meteoric rise, although higher configuration of high-priced way, from the engine to the fuel tank is almost dependent on imports (basically for the domestic steel body) 60 Jiangsu Komatsu excavator, now mostly a lack of core technology. Core technology is not simply look at how much the well-known parts, but look at the whole assembly of excavators match to what extent, how the stability of the sample. 60 Anhui Komatsu excavator, Komatsu excavator 60, Kim Ho-hand excavator sales by Shanghai Jin Hao Used Construction Machinery Co., Ltd ..
