Engine Room Crane; Double-Jib Crane - Man B&W S50ME-B9.3-TII Project Manual

MAN B&W

Engine room crane

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
cross-hatched 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.

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 is used, it may not fit directly to the overhaul tools, and the use of an interme-
diate 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 H).
2) The hatched area shows the height where an MAN B&W Double-Jib Crane has to be used.

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 separate
drawing with information about the required lifting
capacity for overhaul of turbochargers.
