Introduction
The standards are GB/T 15706 in the divided class C standard.
In the scope of this standard it is indicated in four forged eyebolts and associated risk factors involved, dangerous conditions and injury events.
For equipment designed and manufactured according to the class C standard, when certain predetermined criteria for Class C and Class A or Class B standard regulations vary
At the same time, it should be given priority C class standards.
General lifting four forged eyebolts
1 Scope
This standard specifies the general lifting four forged eyebolts basic parameters, performance and critical dimensions, these characteristics of the eyebolts
And compatibility with the other components equipped with necessary. Such eyebolts can be used for vertical and oblique lifting loads.
This standard specifies the size of the eye for eye bolts and shackles for the same working load limit of GB/T 25854 defined
Directly attached. Can also be designed larger size and eye, so that the chain can hook assembly have the same working load limit directly attached.
The standard Chapter 4 identified all major risk factors related to 4 eyebolts, dangerous conditions and damage events.
The standards required four eyebolts temperature range of -20 ℃ ~ 200 ℃.
This standard does not apply to non-integral forged eyebolts.
This standard does not apply to standard before publication produced four forged eyebolts.
