) The lifting tools for the engine are designed to t together
with a standard crane hook with a lifting capacity in ac-
cordance with the gure stated in the table. If a larger
crane hook is used, it may not t 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
DoubleJib Crane has to be used.
079 43 11-5.1.0
The crane hook travelling area must cover at least
the full length of the engine and a width in accord-
ance with dimension A given on the drawing, see
crosshatched area.
It is 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 this drawing.
The crane hook should at least be able to reach
down to a level corresponding to the centre line of
the crankshaft.
For overhaul of the turbocharger(s), trolley mount-
ed chain hoists must be installed on a separate
crane beam or, alternatively, in combination with
the engine room crane structure, see ‘Crane beam
for overhaul of turbochargers’ with information
about the required lifting capacity for overhaul of
turbocharger(s).
