3 Crane inspection points
The inspection instructions that are specific to the hoist should primarily be applied when inspecting the
hoist. The table below lists some general crane inspection points and inspection methods. The inspection
interval for a crane in continuous duty is 1 week. Cranes in intermittent duty should be inspected before
being used. The measurements to be taken at the inspection points are necessary if other methods do
not produce an adequate result. If any defects or abnormalities are observed, they must be investigated
and corrective action must be taken in accordance with the instructions specific to that device.
