High-Strength Excavator Standard Arm for 50 Ton Machines

Anti-Corrosion Coating Used for Cat 349 CAT352 50 TONS MACHINE

The Caterpillar CAT 352 is a large hydraulic mining excavator renowned for its robustness, productivity and

reliability in demanding applications such as heavy excavation, quarrying and topsoil removal. The key

component determining its working radius, digging depth and lifting capacity is the standard boom (digger arm)

configuration.

• High Breakout Force: The robust boom structure effectively transfers the hydraulic power of the boom cylinders into tremendous digging (crowd) force at the bucket, essential for fracturing hard ground and rock.

• Significant Lifting Capacity: The standard boom allows the CAT 352 to lift substantial loads (often exceeding 30+ metric tons, depending on radius and configuration) safely and efficiently, crucial for handling large boulders or heavy materials.

• Durability & Long Life: The combination of high-strength materials, robust construction, and effective reinforcement ensures the standard boom delivers exceptional durability and a long operational life, minimizing downtime in critical mining operations.

• Stability: The boom's weight and strength contribute significantly to the overall stability of the machine during digging and lifting, especially when combined with the large undercarriage.
