Quick coupler for hydraulic pressure inspection provides easy troubleshooting. Automatic lubrication system is standard. Back To Top Increased Reliability Plate thickness of the revolving frame and center frame has been increased and stiffener plates have been added to improve durability. Boom and arm have increased section height and plate thickness, as well as continuous both-side groove welding, improving digging and side contact strength. Large-capacity triple roller bearings are used on swing circle, providing lifetime durability in the most severe mining applications.
Undercarriage is strengthened to provide excellent reliability and long life.
