21.8t excavator dual flow hydraulic piping kit in stock
FR220D2 adopts a YA-NMAR engine excellent in environmental protection and energy saving. Moreover, it uses a load sensitive hydraulic system, able to guarantee operator's better controlling of the machine and better movement coordination, reduce the demand for operation proficiency of the driver; in addition, the reliability of this system has been recognized by the majority of users. The stress analysis and structure optimization of such key components platforms, swing arms, bucket rods and lower chassis has fully guaranteed the reliability of the structural members. The daily maintenance is sufficiently convenient and you only need to open the rear hood for maintenance of the engine oil, fuel and air filters.
