The mechanism (motor and gear; not applicable to wearing parts) of the ST chain hoist is
classified according to ISO. The theoretical full load lifetime in hours shown opposite (D)
is applicable for normal hoist applications.
If the full load lifetime (D) minus the lifetime expired is nought, the wire rope hoist must
be overhauled by the manufacturer.
