Product Description
ZHONGHE Sliding Arm: Precision Engineering for Demanding Applications
Core Technical Advantages
Dual-Limit Vibration Control System
• Industry-first design eliminates operational vibration
• Significantly reduces operational vibration of telescopic cylinders
• Prevents cylinder over-extension damage(The cylinder is also protected by double seals.)
→ Substantially enhances cylinder durability 
Wear-Resistant Slider Innovation
• Replaced pulley mechanism with wear plastic sliders
• Modular design enables quick replacement and maintenance
→ Reduces downtime costs by 40% vs traditional systems
Reinforced Structural Design
Single-Plate Cover Technology
• Critical load-bearing covers CNC-cut from single steel plates
• Precision machining ensures deformation control under load
→ Eliminates structural deformation risks
Active Corrosion Prevention
• Strategically positioned drainage holes in arm tubes
→ Effectively mitigates internal water accumulation and corrosion
Ideal Applications
• Subway tunneling • Foundation excavation • Caisson construction
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.
