Product Description
Manufactured from first-class Q355B wearable steel, this extended reach structure undergoes advanced forging processes to resist extreme mechanical stresses in earth-moving operations. The heavy machinery boom assembly is treated to achieve a surface hardness of HRC52-58 with an 8mm to 12mm hardening depth, directly mitigating abrasive wear during river dredging or deep ditch excavation. Integrated with precisely machined bucket cylinders, high-pressure hydraulic hoses, and specialized H-linkages, the entire digging geometry is engineered for optimal payload retention. Furthermore, structural integrity is strictly verified through mandatory welding quality inspection and dimensional testing, preventing micro-fractures under heavy lateral loads.
Application
The two-section long reach boom and arm is engineered for heavy earth-moving jobs where extended working range and structural stability are critical. Available in both two-section and three-section configurations, this assembly performs exceptionally well in deep excavation and waterway maintenance where standard excavator attachments cannot operate effectively.
Typical Applications:
- Construction transportation of sand and concrete materials
- Slope repairing and grading for expressways
- Dredging and desilting operations in river courses
- Earthwork excavation for large building foundations
- Deep ditch trenching and complex earth-moving tasks
