Inspection of the load chain (model C85 - roller chain)
Load chains must be inspected for mechanical damage at annular intervals. Inspect the load
chain for sufficient lubrication and check for external defects, deformations, superficial cracks,
wear and corrosion marks.
Roller chains must be replaced when the chain has elongated over one pitch ´pn´ or over 49
pitches (11 x pn) by 3 %.
Nominal dimensions and wear limits are shown in table 2. If one of the limit values is reached,
the load chain must be replaced.
