Product Advantages
Unmatched Structural Stability:
The one-piece welded construction minimizes vibration and flex under extreme loads, ensuring accurate operation and extending service life.
Enhanced Digging Force:
Optimized weight distribution and rigid design maximize breakout force, enabling efficient excavation of compact soil, rock, and debris.
Low Maintenance Costs:
Fewer moving parts compared to telescopic arms reduce wear and tear, cutting down on repair frequency and operational expenses.
Universal Compatibility:
Customizable mounting brackets fit 5–30 ton excavator models, offering a cost-effective upgrade for diverse heavy machinery fleets.

Craft & Technology
Precision Cutting & Forming:
CNC plasma cutting ensures consistent arm dimensions, while cold forming preserves steel tensile strength, avoiding material fatigue caused by high-temperature processing.
Robot Welding Process:
Automated robotic welding guarantees uniform weld seams, eliminating human error and enhancing structural rigidity. All welds undergo ultrasonic flaw detection to meet industrial quality standards.
Stress Relief Treatment:
Post-welding heat treatment reduces internal stress, preventing deformation during long-term heavy-load use and ensuring dimensional stability.
Durable Surface Protection:
A 3-layer coating system (phosphatization + primer + topcoat) provides superior resistance to rust, abrasion, and harsh environmental conditions, suitable for outdoor and marine construction sites.
Application Fields
Construction & Infrastructure:
Foundation digging, trench excavation for pipelines and cables, and material loading in building projects.
Mining & Quarrying:
Breaking and loading ore, overburden removal, and slope stabilization in open-pit mines.
Agriculture & Landscaping:
Ditching for irrigation systems, land leveling, and pond excavation for farmland improvement.
Demolition & Recycling:
Structural debris handling, concrete breaking auxiliary operations, and waste sorting in demolition sites.
FAQ
Q: Can the fixed excavator arm be retrofitted to my old excavator?
A: Yes, we offer customized mounting brackets to fit most excavator brands (e.g., Caterpillar, Komatsu, Hitachi). Just provide your excavator model and tonnage for a perfect match.
Q: How does it compare to a telescopic arm in terms of efficiency?
A: The fixed arm excels in high-force, repetitive tasks like heavy digging, as it has no telescopic mechanism lag. It is more durable and cost-effective for applications that do not require variable reach.
Q: What maintenance is required for the fixed arm?
A: Regularly inspect weld seams and coating integrity; lubricate connection points monthly. Avoid overloading beyond the rated capacity to prevent structural damage.
Q: Is the product compliant with international standards?
A: Yes, our fixed excavator arms are certified to ISO 9001 quality management standards and CE safety standards, suitable for global market sales and use.
