For Grade 8

Nominal diameters and pitchs in brackets should be avoided with new constructions.

-Perfect fit of a chain to the sprocket-wheel will be secured, if the sprocked-wheel is placed at manufacturer''s disposal.

-The chain link must not be streched by the joining element of the hoist conveyor in the last link of the chain multiple pitch length.
