Hook connecting parts
The hook is mainly used in a component on the lifting equipment. So what do you need to use when connecting the hook to the lifting equipment? Shackles are required when connecting hooks. So how are shackles used? What are the basic things to pay attention to?
How to use the shackle series products and what to pay attention to
Before operation, check whether the shackle types used can match and whether the joints can be robust and reliable.
Prevent the use of bolts or metal rods instead of pin shafts.
There are no major impacts or bumps during the lifting process.
The pin shaft should be transformed and active in the bearing hole, and no clamping is allowed.
The shackle body shall not bear lateral bending moment operation, that is, the bearing capacity shall be within the plane of the body.
When the bearing capacity in the body plane has different angles, the maximum working load of the shackle is also adjusted.
The maximum angle between the two leg riggings carried by shackles shall not be greater than 120°.
The shackle should correctly support the load, that is, the force should be along the axis of the middle line of the shackle to avoid bending and unstable loads, and should not be overloaded.
Avoid shackle-pain loads.
When shackles are used to bind the rigging with the wire rope, some of the cross pins of the shackle should be connected to the cable eye of the wire rope to avoid the conflict between the wire rope and the shackle when the rigging is lifted, forming the cross pin and the buckle to disengage.
A reasonable punctual inspection should be determined based on the frequency of use and the degree of harsh working conditions. The punctual inspection period should not be less than half a year, and the maximum length should not exceed one year, and inspection records should be made.
If used in high temperature environments, load reduction should be considered, see the following table:
Temperature: New load after load reduction due to temperature increase
-40℃~200℃: 100% of the original rated load
200℃~300℃: 90% of the original rated load
300℃~400℃: 75% of the original rated load
