The supporting parts are made of integrated cast steel parts. The robot welding guarantees more stable welding seam quality. The proprietary structural parts stress release technology gives a longer life of the machine, and the average stress is 12-15% lower than that of the same class, while the bucket rod is 18-32% lower than that the same class.

Track roller, carrier roller, sprocket, idler and crawler of a level of 150 tons and above adopted, the bearing capacity has been improved by 30% by increasing the axle diameter.

Adopting X-type high clearance chassis, equipped with standard H-frame bottom protection mechanism. Compact longitudinal beam, high passing ability chassis, high strength, good passing ability, the chassis is equipped with standard full protection chain-track protection device.

Equipped with high-performance mining engine, it is so powerful. Low fuel consumption, easy maintenance, 500h planned maintenance program available* (* Use XCMG pure engine oil, carry out the maintenance and sample inspection according to the Operating Manual and QSK23 Operation and Maintenance Manual.

The machine can adapt to the needs of a variety of working conditions, configure different operating modes and a variety of bucket specifications, achieve the best excavation conditions, and have a wider range of applications.
