► Adopting whole brazing technology and new-type radiator welded by robots, and configuring positive pressure degassing type expansion tank,to improve the pump life, which can quickly remove the gas within engine and waterway, reduce the rust and meet 50t environmental operating
► The turntable adopts a rigid box structure to provide higher strength and improve the cab shock absorption ability. The engine mounting base
structure is strengthened to improve shock absorption
► With main body adopting I-beam rigid structure, the whole machine's strength is intensified, and the turntable side beam adopts the D-tube structure to improve its ability to resist external impact
► The travelling mechanism adopts strengthened key parts of the chain rails bearing stress to improve the strength and impact resistance of the chain rails, and the service life of the track is greatly improved. With strengthened X-beam section, and the strength of the end face is greatly improved by increasing the size, thickness and structure of the box beam
► The working equipment adopts the casting type single connecting rod to fully optimize the stress distribution, which greatly improves the reliability. The boom arm shaft seat adopts the forging-type shaft seat, and higher wear resistance can be achieved through the quenching and tempering treatment
► Replace the XCMG new second generation bucket to make the force more reasonable and increase the durability.
