Installation and Usage Guidelines:

Ensure the eye bolt thread is fully screwed in by using a sufficiently long thread hole.

• Manually screw the eye bolt thread securely and tightly to the contact surface; avoid tightening with tools.
• When lifting vertically, ensure the load is within reach of the loading ring.
• The product can rotate under the rated load but is not suitable for continuous rotation at full load in a 90° direction.
• All operations must strictly adhere to the product operation manual.

Acceptance Procedure:

• Dimensional Acceptance: Ensure compliance with relevant standards, absence of cracks or defects, and a clear indication of specifications, bearing capacity, and material code on the eye bolt surface.
• Thread Acceptance: Visually inspect the thread for intactness and lack of damage. Test using a thread ring gauge (drift diameter gauge, no-go gauge) with an accuracy of 6g.
• Perpendicularity Check: Verify that the thread axis of the eye bolt is perpendicular to the bearing surface. Rotate a go gauge to fit the thread root with the bearing surface without clearance, indicating acceptable perpendicularity.
• Documentation: Provide a certificate of delivery or detailed written test report for archival purposes for all accepted eye bolts.

Operation Restrictions:

• Temperature Range: The operating temperature should be between -40°C to 400°C. For temperatures exceeding 200°C, consult the manufacturer for guidance.
• Chemical Environment: Avoid contact with acid, alkali, or vapours. For applications in chemical environments, contact Vanguard Steel Ltd for guidance.
• Safety Warning: Do not exceed the maximum safe lifting load.

Installation and Operation Precautions:

• Maximum Lifting Weight: The maximum lifting weight (safe working load at limit) of the eye bolt applies only when installed on steel, cast steel, or non-cast iron parts.
• Threaded Hole Area: Keep the area around the threaded hole smooth, and ensure the hole depth is sufficient to fully lock the bolt.
• Proper Installation: Screw the eye bolt in to make the bearing surface fit closely, but do not forcefully tighten it with tools. Failure to screw it in properly may cause deformation or breakage of the eyebolt.
• Lifting Angle: Lift the goods according to the safe working load angle of the eye bolt. Install the eye bolts at different positions based on the specific lifting mode. Avoid moving the center of gravity during lifting.
• Lifting Points: Install the eye bolts according to the number of lifting points designed on the workpiece. Do not reduce the number of lifting points.
• Slow Hoisting: Slowly hoist the goods to avoid impact from fast lifting.
• Prohibited Actions: Do not engage in any illegal operations.

Storage Guidelines:

Vanguard lifting eye bolt products should be stored in a clean, dry place, free from corrosion and oil. Ensure that the threads are well protected from collisions.

Warning:

• Is there a risk of heavy objects falling off during abnormal assembly and hoisting operations?
• Falling heavy objects can cause serious injury or death.
• During installation, and before each use, a visual inspection should be done paying special attention to corrosion, wear, cracks, or deformation.
• Ensure that the thread of the bolt matches the threaded hole.
