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);
● Strictly follow the operation manual during use.

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.

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.

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 not 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;
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%.

2. A thorough examination must be carried out by competent person in accordance with national standards every 12 months, if used frequently,the periodic examination frequency may be increased as propriate and inspection records should be kept;

3. The eyebolt surface shall be cleaned before inspection to ensure clear examination;

5. If any signs that may affect the safety and functionality of the eyebolt are found during inspection, 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.

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

Caution
The plane of the eye of each of a pair of eyebolts should ideally be within ± 5° of the plane containing the axes of the two eyebolts (see the figure). If at first this condition is not fulfilled, it can be achieved by the insertion of shims (spacing washers) which should not exceed in thickness, half the pitch of the relevant screw thread, or by machining the contacting surface. Under no circumstances should the eyebolt be over-tightened in an attempt to achieve correct alignment. Care should also be taken to avoid an alignment whereby the application of the angular load tends to unscrew the eyebolt from its seating.
