2 Crochet de grue à tonne

Product Overview

Le 2 ton crane hook is a fundamental and critical lifting component designed for safe and efficient material handling. Engineered to handle loads up to 2 metric tons (approximately 4,409 lbs), this hook serves as the primary point of connection between the crane’s hoisting mechanism and the load. It is built to the highest standards of durability and safety, making it an indispensable tool in various industrial, construction, and manufacturing settings. Its robust design ensures reliable performance under rigorous working conditions.

2 Fonctionnalités de clés de crochet Ton Crane

• 1. High-Strength Forged Steel Construction: Manufactured from high-grade alloy steel through a precision forging process, our hook offers superior strength-to-weight ratio, excellent impact resistance, and exceptional durability.

• 2. Loquet de sécurité: Equipped with a spring-loaded safety latch that automatically closes the throat of the hook to prevent slings, chaînes, or ropes from accidentally disengaging, significantly enhancing operational safety.

• 3. Precision Machined Surfaces: All load-bearing contact surfaces are precisely machined to a smooth finish. This minimizes wear and tear on lifting slings and other accessories, extending their service life.

• 4. Traitement thermique: The hook undergoes specialized heat treatment (quenching and tempering) to achieve an optimal balance of hardness and toughness, preventing deformation under full load.

• 5. Durable Corrosion Protection: Finished with a high-quality electroplated coating or durable paint, providing excellent resistance to rust and corrosion, which is essential for both indoor and outdoor applications.

• 6. 100% Tests de charge: Every single hook is proof-tested to 125% of its rated capacity (2.5 tonnes) before leaving the factory, ensuring absolute reliability and compliance with international safety standards.

2 Ton Crane Hook Manufacturing Process

The manufacturing of our 2 ton hook follows a rigorous, multi-stage process to guarantee quality and safety:

• 1. Forgeage: A single piece of high-tensile alloy steel is heated and forged under immense pressure. This aligns the metal’s grain structure, creating a part with superior strength and fatigue resistance.
• 2. Rough Machining: The forged blank is initially machined to achieve the basic hook shape and dimensions.
• 3. Traitement thermique: The hook is subjected to a controlled process of quenching and tempering. This enhances its mechanical properties, providing the necessary hardness on the surface while maintaining a tough, shock-absorbent core.
• 4. Usinage de précision: Critical areas, such as the shank thread and the load-bearing saddle, are precision-machined to ensure perfect fitment and smooth operation with other components.
• 5. Surface Finishing: The hook is cleaned and treated with a protective coating (electroplating or paint) to resist environmental damage.
• 6. Assurance qualité & Tests de charge: Each hook undergoes a thorough visual inspection, dimensional check, and a final proof load test to 2.5 tonnes. Certified test reports are available upon request.

FAQ: 2 Crochet de grue à tonne

Q1: What is the safety factor of this 2-ton hook?

UN: Our hooks are designed and manufactured with a minimum safety factor of 5:1 against yielding, in accordance with leading international standards like DIN and ASME. This means the hook is designed to withstand a force five times its rated capacity before permanent deformation occurs.

Q2: How often should the crane hook be inspected?

UN: It is recommended to perform a visual inspection before each use. A formal periodic inspection by a qualified person should be conducted at least every 12 mois, or more frequently depending on the severity of service, as per OSHA, LOLER, or other local regulations.

Q3: Can the safety latch be removed or deactivated?

UN: No. The safety latch is a critical safety device. Removing or deactivating it is extremely dangerous and violates safety standards. It must always be functional and in good condition.

Q4: What are the signs that my hook needs to be replaced?

UN: Replace the hook immediately if you observe any of the following:

• Visible cracks or nicks.

• Throat opening has increased by more than 15%.

• Hook twist exceeds 10 degrés.

• Excessive wear at the saddle or tip.

• Any deformation from its original shape.

Q5: Is the thread on the hook compatible with my hoist?

UN: Our 2-ton hooks are manufactured with standard metric or imperial threads (Par exemple, M24, 1"). Please check your hoist’s specification or contact our technical support team to confirm compatibility before ordering.
