OEM-Quality Caterpillar 6030 Track Frame Assemblies

Restore undercarriage structural integrity and alignment on your 300-tonne hydraulic excavator with heavy-duty Caterpillar 6030 Track Frames (Side Frames). Precision-manufactured for Caterpillar 6030 / 6030 FS (formerly Bucyrus RH120-E / O&K RH120) excavators and face shovels, these heavy structural side frames provide the primary load-bearing foundation for the entire lower undercarriage.

Built from heavy-section steel plates welded under strict structural standards, these track frames are fully stress-relieved to resist fatigue, twisting, and cracking under severe digging leverage, continuous track recoil loads, and rough bench movement.

Key Features & Benefits

• Heavy-Section Steel Box Construction: Fabricated from high-tensile, impact-resistant steel plate to absorb severe lateral loads and high torsional stress during heavy digging cycles.

• Precision-Machined Roller & Final Drive Mounts: Line-bored and CNC-machined mounting locations ensure exact alignment for travel final drives, front idlers, bottom rollers, and carrier rollers—preventing uneven track chain wear.

• Integrated Hydraulic Track Tensioning Guides: Precision-machined internal guide channels house the hydraulic track recoil cylinders and front idler yokes for reliable track tension maintenance.

• Stress-Relieved Weldments: Fully heat-treated/stress-relieved structure to eliminate internal residual weld stress, preventing frame cracking in cold-weather or high-impact mining applications.

• Direct OEM Carbody Bolt-In: Precision-drilled connection flanges ensure direct bolt-on fitment to the central carbody cross-member on standard Caterpillar 6030 lower undercarriages.
