Excavator Arm Repair: Heavy Equipment Maintenance

The repair process addresses stress cracks in the 20mm thick HY80 steel, restoring 95% of original load capacity (8,500kg). Includes replacement of 4 hydraulic cylinders (250bar working pressure) and pivot bushings. Proper repair extends service life by 5,000 operating hours while preventing 80% of potential hydraulic failures. Requires post-weld heat treatment to maintain 345MPa yield strength. Though labor-intensive, this maintenance prevents $15,000 replacement costs.
