Simplified Maintenance

• Segmented upper arm pipe design
  → Enables rapid component replacement without full disassembly

​

Primary Applications:
Driving/extracting:

• Sheet piles (Larsen/FZ types)

• Steel rail piles

• H-beam piles
  Critical foundation projects:

• Flood control barriers

• Embankment reinforcement

• Drainage systems

• Retaining walls

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.
