Product Features

● The eyebolt can rotate 360° and pivot up to  230° for lifting. A 4× safety factor is guaranteed in any permitted force direction.
● Forged from high-strength Cr-Mo alloy steel,quenched and tempered to ensure sufficient strength and toughness.
● Manufactured and tested in accordance with EN1677-1 and other relevant standards;certified with EuroCert CE for quality and safety compliance .
● Metric threads meet DIN EN 13 (M-6g),UNC threads comply with ASME/ANSI B18.3.1M (UNC-2A).100% go-no go tested,with a 6g outer diameter tolerance grade.
●100% magnetic particle inspected to ensure zero cracks.
● Withstand at least 20,000 cycles of dynamic fatigue test under 1.5 times the working load limit.
● The products are subject to dynamic fatigue limit test for 20,000 times under 1.5 times of working limit load.
● The eyebolt base with hexagonal design is easy to install and disassemble.

User Instructions
● Ensure the tapped hole has sufficiently threaded length to engage the eyebolt shank fully;
● The eyebolt thread shall be  securely fastened and tightly fitted  to the contact surface (Tighten manually; no tools shall be used for fastening);
● When the loading ring is oriented for vertical lifting direction, the maximum load capacity can reach.
● The eyebolt can rotate under rated load. However, it is not suitable for permanent rotation at full load in 90°direction.
● Strictly follow the operation manual during use.

User Instructions
● Ensure the tapped hole has sufficiently threaded length to engage the eyebolt shank fully;
● The eyebolt thread shall be  securely fastened and tightly fitted  to the contact surface (Tighten manually; no tools shall be used for fastening);
● When the loading ring is oriented for vertical lifting direction, the maximum load capacity can reach.
● The eyebolt can rotate under rated load. However, it is not suitable for permanent rotation at full load in 90°direction.
● Strictly follow the operation manual during use.

Acceptance Procedures
1. The overall dimensions shall comply with the corresponding standards to ensure there are no cracks or defects, and its specifications, load capacity and material code shall be clearly marked on the eyebolt surface;
2. Acceptance of thread: visually inspect threads are full and free of scratches or impacts,test with the thread ring gauges (go/no-go gauge) to ensure accuracy of 6g.
3. The thread axis of the eyebolt must be perpendicular to the bearing surface. Rotate a go gauge to fit the thread root with the contact surface without clearance,that is, the perpendicularity is acceptable;
4. Acceptable eyebolts shall be provided with a manufacturer's certificate or a detailed testing report for filing.

Usage Restrictions 

1. Operating temperature range: - 40 ℃ to 400 ℃ (please consult the manufacturer for use beyond 200 ℃);
2. Eyebolts should not be immersed in acidic solutions or exposed to acid fumes or other chemicals.For any application in a chemical environment, please contact the Technology Department of PINGLI.
3. Warning: Do not exceed the maximum safe working load.

Precautions for Installation and Operation

1. The maximum lifting capacity (safe working load limit) of the eyebolt is only applicable when the eyebolt is installed on steel, cast steel or non-cast iron workpieces for operation;
2. The contact surface around the tapped hole must be kept flat,and  the drilling depth shall be sufficient to fully secure the bolt in position;
3. The eyebolt must be screwed in until the bearing surface is tightly fitted, but no tools are allowed to apply force for tightening; if not screwed in place, the eyebolt will be deformed or fractured;
4. Please lift according to the safe working load angle of the eyebolt. The eyebolts must be installed in different positions according to different lifting methods and do not move the center of gravity during lifting.
5. Please strictly install the eyebolts for lifting according to the number of designed lifting points  on the workpiece, and do not  reduce the number of lifting points for lifting.
6. Use slow lifting during hoisting to avoid rapid impact lifting.
7.It is strictly forbidden to operate in violation of regulations,including:
● Altering the structure of the eyebolt;
● Subjected the eyebolt to lateral force;
● The eyebolt is obviously deformed or severely worn;
● The thread is damaged;
● The eyebolt is not fitted with the bearing surface;
● Lifting method is within the marked range.

Maintenance and Periodic Examinations

1. Enterprises are required to conduct an internal safety inspection quarterly each year and keep inspection records;
2. A thorough examination shall be performed by competent person  in accordance with national standards annually, if used frequently,the periodic examination frequency shall be shorten as ppropriate and inspection records shall be kept;
3. The eyebolt surface shall be cleaned before inspection to ensure clear examination;
4. Pay attention to signs that may affect safety and functionality , such as: thread defects, cracks, grooves, deformation, obvious signs of overheating or the cross-section wear exceeds 10%.
5. If ant signs that may affect the safety and functionality of the eyebolt are found during examination, the eyebolt should be eliminated and scrapped;
6. In case of any doubts or damage to the eyebolt, please stop the operation immediately and request a professional inspection.

Warehousing

PINGLI lifting products shall be stored in a clean, dry, corrosion-free and oil-free environment. The threads must be properly protected from collision.
