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.

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

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

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

                                  Graphite alloy copper sleeve                                                                                                    Steel sleeve

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.

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.

Precision Manufacturing Process: Strength Built on Quality

ZHONGHE's manufacturing prowess is the foundation of our product excellence. We implement a strictly controlled, lean production process:

1. Precision Design & Material Selection:

Professional structural design and stress analysis based on application requirements.

Strict sourcing of top-tier global steel (e.g., Hardox wear plate, BS700/Q690D/Q355B structural steel).

2. High-Precision Cutting & Forming:

CNC plasma/flame cutting ensures dimensional accuracy with minimal thermal distortion.

Large structural components are precision-formed using heavy-duty press brakes and plate rollers.

3. Advanced Welding Technology:

Operated by internationally certified senior welders.

Extensive use of high-strength processes like GMAW (Gas Metal Arc Welding).

Critical joints feature double-beveled groove preparation (45°) with gas-shielded welding.

Key structural areas utilize double-pass welding.

4. Precision Machining & Assembly:

Large double-sided floor boring mills ensure high concentricity (±1mm tolerance) for pivot booms, extending lifespan.

5. Triple-Check QC Protocol: Zero Tolerance for Defects:

Design Review: Rigorous approval of drawings and technical plans.

In-Process Verification: 100% inspection after each manufacturing stage, checking prior process outputs. Problems are halted before proceeding.

Final Inspection: Our independent QC Department performs comprehensive checks, including:

Weld quality.

Critical dimensional accuracy (CMM - Coordinate Measuring Machine, ±1mm tolerance control).

Hydraulic system pressure and seal integrity tests.

Functional tests (range of motion, limit switch protection).

Only products passing all three mandatory quality gates receive shipment authorization.
