High Quality Demolition Arm for Cat320 Excavator Construction Machinery Part

Product Specification

Product Description

DEMOLITION BOOM CORE ADVANTAGES (Engineered for Power & Durability):

Superior Materials & Construction:

• Seamless Precision Hydraulic Tubing: Ensures structural integrity and leak-free operation under high pressure.

• Integrated Centralized Lubrication System: Reduces wear at critical pivot points and extends component life.

• High-Strength Boom Base: Features monolithic (one-piece) forged base sleeves for maximum load-bearing capacity and rigidity.

• Premium Wear Components: Graphite alloy copper sleeve at high-stress pivots for superior wear resistance and longevity.

Optimized Design for Performance & Serviceability:

• Modular Hydraulic Line Design: Facilitates faster maintenance and component replacement.

• Structural Reinforcement: Internal transverse reinforcement ribs within the middle box section significantly increase tensile strength.

• Oversized Bucket Cylinder: Provides increased breakout force and productivity for demanding demolition tasks.

• Protected Hydraulic Routing: Key pipelines are routed internally for impact protection, preventing crushing damage.

• Heavy-Duty Pivot Pins: Employs 90mm diameter hardened pivot pins to eliminate shear failure risk.

Enhanced Geometry & Reach:

• Stress-Optimized Geometry: Boom, intermediate arm, and stick lengths are proportionally engineered for optimal force distribution and structural efficiency.

• Maximum Articulation: Achieves a working angle approaching 180° between boom and arm, maximizing reach and versatility in confined spaces.
