36.3.7 Outline wear
H2
P = Pitch
H2 = Nominal disc height.
H3 = Minimum disc height.
A new lift chain has a specific nominal disc height, defined as H2 in the
figure. As the truck is used the lift chain wears radically, on the side that
runs over the chain sprocket. The minimum disc height is define as H3
in the figure and denotes the minimum permitted value of the disc
height.
Maximal permitted outline wear is 5% of the height H2. If a lift chain
reaches the maximum level of wear, the chain should be replaced.
The nominal and minimum disc heights for respective lift chains are
stated in the table in the chapter "Stretching".
36.3.8 Stretching
The amount of stretch on a lift chain is measured on the part of the
chain that runs over the chain sprocket. The amount of stretch may, at
the most, be 2% on the most worn section of the chain. Measurement is
suitably made over 300-1000 mm of the chain.
The nominal and maximum permitted chain lengths for lift chains are
stated in the table below.
