USER INSTRUCTION MANUAL MEGA EYEBOLT
The installation must be carried by a competent person. Eyebolts must be
operated in compliance with the 2006/42/CE standard (new machinery
directive) with following adjustments.
1. Check eyebolts’ location to assure the load be evenly distributed to
each eyebolt.
2. If the load is asymmetric, increase the eyebolt size or have engineer to
design the lifting points if it is needed.
3. Check object material. The minimum depth of the threaded hole must
be achieved. Factor of depth to diameter of the eyebolt is as following
and a longer bolt is needed if the factor is over 1.
• Steel/Stainless Steel – 1
• Cast iron – 1.25
• Aluminum alloy – 2
• Aluminium magnesium alloy – 2.5
4. The material of the object matched with the lifting eyebolt must have a
tractive resistance equal or over the standard tractive resistance of steel
in EN 10025 S235JR.
5. The thread must be perpendicular to the surface of the object being lifted.
6. Eyebolt should be tightened with a torque wrench as to the below chart.

USER INSTRUCTIONS
All liftings eyebolts shall have a regular inspection and it shall be recorded
with following information.
1. Visual inspection for corrosion, crack and other deformations. Marking
should be clearly visible.
2. Check threads worn by thread gauge for old eyebolts. The designed
thread tolerance is 6g, worn threads will affect WLL.
3. The load to be lifted must not exceed the working load limit.
4. Check for excessive wear on the bearing
area of the eye; it must not be used if the
diameter of the bearing area has wear of ≥ 5%,
compared to the original size.
5. After the eyebolt is xed in object, check the
eye movement to make sure it can rotate
freely, and it can swivel in specied angle
range.
