1) The lifting tools for the engine are designed to fit together
with a standard crane hook with a lifting capacity in accordance
with the figure stated in the table. If a larger crane
hook <strong>is</strong> used, it may not fit directly to the overhaul tools,
and the use of an intermediate shackle or similar between
the lifting tool and the crane hook will affect the requirements
for the minimum lifting height in the engine room
(dimension B)
2) The hatched area shows the height where an MAN B&W
Double-Jib Crane has to be used.

The crane hook travelling area must cover at least
the full length of the engine and a width in accordance
with dimension A given on the drawing, see
cross-hatched area.
It <strong>is</strong> furthermore recommended that the engine room
crane can be used for transport of heavy spare parts
from the engine room hatch to the spare part stores
and to the engine. See example on th<strong>is</strong> drawing.

The crane hook should at least be able to reach
down to a level corresponding to the centreline of
the crankshaft.
For overhaul of the turbocharger(s), trolley mounted
chain ho<strong>is</strong>ts must be installed on a separate crane
beam or, alternatively, in combination with the engine
room crane structure, see ‘Crane beam for overhaul
of turbocharger’ with information about the required
lifting capacity for overhaul of turbocharger(s).
