Optimized Excavator Boom Design for Heavy-Duty Performance
The excavator boom is fabricated from high-strength Q355B steel, delivering exceptional durability and structural stability. The extension arm sleeve utilizes 45# steel as the base material, further reinforced with a 40Cr bushing lining to improve wear resistance and prolong component lifespan.
To reduce shear stress generated by repeated shaft-sleeve rotation, a butter grease lubrication system is integrated, effectively minimizing friction and enhancing longevity.
A standout innovation in this design is the hydraulically driven extension arm, strategically positioned between the body support and working arm. Powered by dedicated oil cylinders, it works in synchronization with the bucket cylinder to maximize operational efficiency and power output.
The system features dual control interfaces (both inside and outside the cockpit), allowing independent operation of each hydraulic cylinder set for precise, responsive maneuvering.
Ideal for Demanding Environments:
Mining & quarrying operations
Port logistics & bulk material handling
Emergency flood control & disaster rescue missions
This cutting-edge design marks a significant leap in excavator technology, offering unmatched performance, durability, and reliability in the most challenging working conditions.
