Plate wear
P = Pitch
H2 = Nominal plate height.
H3 = Minimum plate height.
A new lift chain has a specific nominal plate height, indicated by H2 in
the figure. As the truck is used, the lift chain is subject to radial wear on
the side that passes over the chain wheel. The minimum plate height,
H3 in the figure, indicates the minimum permitted value of the plate
height.
Maximum permitted plate wear is 5% of the H2 height. If a lift chain
has reached the maximum degree of wear, the chain must be re
-
placed.
The nominal and minimum plate heights for the relevant lift chain are
specified in the table in the section "Elongation".
