Material Quality
High-strength steel (such as LG700 or Q355B) offers durability while keeping the arm lightweight.
Reinforced pivot points and multi-layer welding enhance structural strength.
Excavation Depth & Reach
Choose an arm with an optimal telescoping range to suit your worksite requirements.
Some high-quality arms provide an additional 20 cm of digging depth compared to standard models.
Hydraulic Cylinder Design
A double-slider cylinder design helps reduce vibrations and ensures stable movement.
Well-sealed cylinders prevent oil leakage and extend service life.
Bucket Compatibility
Ensure the arm is compatible with different bucket types for various tasks like dredging, deep excavation, or demolition.
Ease of Maintenance
Look for models with an external bucket cylinder design, making replacements and repairs more convenient.
A double-layer hose casing reduces pipeline wear and increases longevity.
