Compared with the previous generation of excavators, the complete XE215CA hydraulic excavator can have its fuel consumption reduced by about 10% and its working efficiency increased by more than 5%, with its earthwork working efficiency highest among its peers. Its reinforced chassis system can have the complete excavator achieve stronger adaptability to mining conditions and a longer service life; its larger fuel tank volume increased by 15% compared with the previous generation can enable the machine to work much longer at one time, the brand-new cab subject to injection molding is configured with standard laminated glass featuring lower noise, its new air-conditioning system can have its air output increased by 23% to achieve a better warming and cooling effect as well as more comfortable operation. This machine is mainly applicable to municipal construction, highway bridges, housing construction, road engineering, construction of water conservancy works, port construction, mines, and other earthwork construction at the advantage of sufficient flexibility, good controllability, low fuel consumption, high construction efficiency, powerful digging strength, comfortable driving environment, wide range of application and other outstanding characteristics.
