FABICK CAT, based in Missouri, USA, faced a significant challenge with a Cat 773 Off-Highway Rock Truck that required repair. To address this, they turned to the hydraulic-powered CLIMAX PM4200 portable mill to repair and remachine a strut mount on the massive truck.

The CLIMAX PM4200 portable mill offers a longitudinal power feed with manually controlled cross-travel and can be directly affixed to the workpiece or a support structure. Users have the flexibility to select X-axis travel ranging from 20 to 78 inches (508.0 to 1981.2 mm).

Similar to the strut mount repair, the PM4200 portable mill is commonly used for milling large, cumbersome parts. Many customers rely on the CLIMAX PM4200 portable milling machines after welding up and re-machining worn parts on production machinery, such as stamping presses. Its versatility allows for the easy machining of long motor mount slots, often without dismantling, since the mill can be mounted right on the workpiece. Additionally, this tool excels at machining motor mounts and pump bases, especially in tight locations.
