10 Dimensões do gancho de guindaste

For a 10-ton crane, understanding its hook dimensions isn’t just technical trivia; it’s critical for safety, compatibility, and optimal operation. As a leading global crane manufacturer, Weihua designs and produces hooks engineered for reliability, adhering to stringent international standards (like DIN, ISO, Fem). Let’s break down the key dimensions you need to know for a typical Weihua 10 gancho de guindaste.

Why Dimensions Matter

Before diving into numbers, remember why these dimensions are crucial:

1. Load Security: The throat opening must be large enough to accommodate slings, shackles, and the load itself securely.

2. Strength & Segurança: Dimensions directly relate to the hook’s structural integrity and Working Load Limit (Wll).

3. Compatibility: Hooks must fit correctly onto the crane hook block or lifting attachment.

4. Rigging Efficiency: The right size hook makes rigging faster and safer.

5. Wear Monitoring: Knowing initial dimensions allows you to measure wear over time (critical for inspections).

Key Weihua 10-Ton Hook Dimensions (Typical Range)

It’s vital to understand that exact dimensions can vary slightly depending on the specific Weihua crane model (Por exemplo, single girder, double girder, hoist type), the hook design (Por exemplo, standard eye hook, clevis hook), and the applicable standard. However, here are the core dimensions you’ll encounter for a standard 10-ton (Wll) forged hook commonly used on Weihua overhead cranes and hoists:

• 1. Throat Opening (A): This is the horizontal distance across the widest part inside the hook’s curve.

  • Typical Range for Weihua 10-ton Hook: Approximately 75 mm - 85 mm (3.0 in – 3.3 in)
  • Why it matters: Dictates the maximum width of slings, shackles, or load attachments that can fit inside the hook safely.

• 2. Hook Height (B): The vertical distance from the bottom of the hook tip to the top of the hook shank (where the nut sits or where it attaches to the swivel/lifting block).

  • Typical Range for Weihua 10-ton Hook: Approximately 170 mm - 200 mm (6.7 in – 7.9 in)
  • Why it matters: Affects the overall hook profile and clearance under the crane structure or near obstacles.

• 3. Shank Diameter (C): The diameter of the threaded portion at the top of the hook.

  • Typical Range for Weihua 10-ton Hook: Approximately 50 mm - 60 mm (2.0 in – 2.4 in)
  • Why it matters: This is a critical strength component. It must match the thread size of the hook nut or the attachment point on the lifting block. Proper torque on the nut is essential for safety. Wear on the shank threads is a serious inspection point.

• 4. Hook Tip Width (D): The thickness of the hook at its tip.

  • Typical Range for Weihua 10-ton Hook: Approximately 40 mm - 50 mm (1.6 in – 2.0 in)
  • Why it matters: The tip experiences significant wear and stress. Minimum tip thickness is a key parameter checked during inspections to ensure structural integrity hasn’t been compromised.

• 5. Hook Throat Depth (E): The vertical distance from the center of the throat opening down to the lowest point inside the hook’s curve.

  • Typical Range for Weihua 10-ton Hook: Approximately 80 mm - 100 mm (3.1 in – 3.9 in)
  • Why it matters: Determines how deeply a sling or load can sit within the hook, affecting stability and reducing the chance of the load slipping out.

Important Considerations for Weihua Hooks

• Trava de segurança: Most Weihua 10-ton hooks come equipped with a spring-loaded safety latch as standard or as a critical option. Ensure the latch functions correctly and is not damaged.

• Material & Marking: Weihua hooks are forged from high-quality alloy steel. Look for the mandatory markings:

  • Wll (10 T or 10000 kg)
  • Grade (Por exemplo, M, P, S – indicating material grade per DIN/ISO)
  • Manufacturer’s Mark (Weihua or WH)
  • Unique Identification Number

• Giratório: Many Weihua hooks incorporate a swivel mechanism above the hook itself. This allows the load to rotate without twisting the wire rope. Dimensions given above usually refer to the hook below the swivel. The overall height including the swivel will be greater.

• NEVER EXCEED WLL: The 10-ton rating is the absolute maximum safe working load under defined conditions. Never lift beyond this limit.

• Consult the Manual! The definitive source for the exact dimensions of the hook on your specific Weihua crane or hoist is the original equipment manual or product datasheet. Contact Weihua or your authorized dealer if this documentation is unavailable.

• Inspection is Paramount: Regularly inspect the hook for wear, deformação, cracks (especially at the tip and shank), corrosion, and proper latch function. Measure wear against the original dimensions. Replace the hook if wear exceeds allowable limits or any defects are found.

While the typical dimensions outlined above (Throat ~75-85mm, Height ~170-200mm, Shank ~50-60mm) provide a solid guideline for a Weihua 10-ton crane hook, always prioritize the specifications for your exact equipment. Understanding these dimensions empowers safer lifting operations, ensures compatibility with rigging gear, and provides the baseline needed for critical inspection and maintenance. When in doubt about the condition or specifications of your Weihua crane hook, consult a qualified inspector or contact Weihua directly. Remember, the hook is your critical link to safety – treat its specifications and condition with the utmost importance.
