Móc nâng nặng thuế

Nhóm Woleua, một nhà lãnh đạo được công nhận trên toàn cầu trong các giải pháp nâng và nâng, brings decades of specialized engineering expertise to every Heavy Duty Lifting Hook they manufacture. Choosing Weihua means investing in:

• 1. Engineered for Maximum Load & Sự an toàn: Every Weihua heavy duty lifting hook undergoes rigorous design analysis and testing, far exceeding international standards like ISO 9001, Nữ, and ASME B30.10. They boast exceptional safety factors (tiêu biểu 5:1 hoặc cao hơn), providing a critical buffer for unexpected stresses.
• 2. Ultra-High Load Capacities: Designed to handle the most challenging lifts, Weihua heavy duty lifting hooks are available in an extensive range of Working Load Limits (WLL), spanning from several tons to several hundred tons. Specific capacities are precisely matched to your application requirements.
• 3. Premium Forged Alloy Steel Construction: Forged under intense pressure from high-grade alloy steel, these hooks possess superior grain structure, maximizing strength, impact resistance, and fatigue life compared to inferior cast or cut hooks. This forging process is fundamental to their heavy-duty performance.
• 4. Advanced Safety Latches (Where Applicable): Many Weihua heavy duty lifting hooks feature robust, spring-loaded or positive locking safety latches. These latches are engineered for secure engagement, preventing slings or load attachments from accidentally dislodging, a vital feature for overhead lifting safety.
• 5. Optimized Hook Geometry: The precise throat opening and tip design ensure easy and secure engagement with shackles, chuỗi, or slings. The smooth, radiused profile minimizes stress concentrations and wear on slings.
• 6. Enhanced Durability & Longevity: Móc cần cẩu Weihua undergo specialized heat treatment processes (quenching and tempering) to achieve the perfect balance of hardness and toughness. High-quality finishes (often electro-galvanized or other corrosion-resistant coatings) protect against rust and abrasion in harsh environments, extending service life significantly.
• 7. Seamless Integration: Weihua heavy duty lifting hooks are designed to integrate flawlessly with Weihua’s own cranes, vận thăng, and winches, as well as other major brands of lifting equipment. Shank types (clevis, eye, ramshorn) and sizes are standardized for universal compatibility.
