Product Features & Material Specifications
The excavator three-section extended arm is manufactured from high-strength Q690 steel, offering excellent load-bearing capacity, wear resistance, impact resistance, and corrosion resistance, ensuring long-term reliable operation even under extreme conditions. Key features include: a multi-stage telescopic mechanism with synchronous hydraulic control for smooth and precise movement; reinforced pivot points with wear-resistant alloy bushings; and a modular design for easy maintenance. The surface is sandblasted and coated with two layers of anti-corrosion coating (epoxy primer + polyurethane topcoat) to enhance durability even in humid, dusty, or coastal environments. All hydraulic components comply with ISO 9001 standards, ensuring leak-free performance and stable operation.
