8.3. Chains
Measure the degree of wear on chains
Notes: Regularly check wear, rust and corrosion of chains.
1
目视检查
目视检查是否存在沟槽、刻痕、焊接飞溅、腐蚀或扭曲
的链节和松弛链条。检查链节之间支撑面是否磨损。
如果链条中的链节表面存在过度凹痕、腐蚀、刻痕、沟
槽、扭曲或磨损，应使用工厂批准的链条更换。
2
测量链节厚度(d)
测量链条几个点的尺寸(d)并计算尺寸(dm)。
dm=(d1+d2)/2≤0.9*dn
dn=标称
t=节距

Visual Inspection
Visually inspect whether chain elements have grooves,
scratches, weld spatters, or corrode, twist or get loose. Inspect
whether the supporting planes are worn between chain
elements.
In case of excess pitting, corrosion, scratches, grooves,
twist or wear on chain elements, the chains must be replaced
by those approved by the factories using such chains.
2
Measure thickness of chain elements (d)
Measure the diameter (d) and dimensions (dm) of chains at
several points.
dm=(d1+d2)/2≤0.9*dn
dn=nominal diameter
t=pitch
