DECK CRANE

DESCRIPTION:
D" crane, short for deck crane is a type of crane mounted on a
ship's deck. These cranes are essential for various lifting
operations, including moving cargo between the ship and the
dock handling equipment on the deck and assisting with the
launch and recovery of smaller vessels.

PURPOSE: Deck cranes serve the primary purpose of efficiently


loading and unloading cargo transferring equipment, and handling
materials between vessels and shore facilities. Seamen
particularly those in deck department roles, are often involved in
the operation maintenance and safe use of these cranes. They
ensure the cranes are used properly for lifting, moving and
securing items during various marine operations.

Loading and Unloading:


Are crucial for quickly transferring cargo, such as containers, bulk
materials, and other goods, between ships and docks.

Equipment Handling:
They facilitate the movement of equipment on and off vessels
between different ships, and onto offshore structures

FUNCTION:
Deck cranes, found on ships and offshore platforms are primarily
used for lifting and transferring cargo equipment, and supplies
between the vessel and docks or other locations. They are also
vital for transferring provisions and personnel to and from tenders
and other smaller boats. Their versatility and lifting capacity make
them essential for efficient and safe marine operations.

LOCATION :
Deck cranes are typically located on the ship's main deck, often
between holds or near hatch covers, to facilitate efficient cargo
handling. They can be positioned on the centerline or transversely,
and some are mounted on hatch covers for movement along the
coaming. The specific location depends on factors like the ship's
design, the type of cargo, and the desired reach

 . Centerline vs. Transverse:


Cranes can be placed on the centerline of the ship, but for
ships with a wide beam, a transverse (side-to-side)
placement might be more practical.

 Hatch Cover Mounting:


Some cranes are mounted on hatch covers, allowing them
to travel along the coaming (the raised edge of the hatch).
 Fixed vs. Mobile:
Cranes can be fixed in position or mobile, with some
capable of rotating 360 degrees for optimal access to
different areas of the deck.
