CARGO HANDLING (PRELIM) Flashcards
Stronger variant of web lashing used for securing heavier RoRo
cargoes such as trailers, roll trailers, and truck vehicles; hence
their alternate names truck lashing / trailer lashing
Features: Uses elephant foot hooks, or slings at the ends
Securing Process: Tighten by hand as much as possible first before
using the ratchet
Typical Length: 3 meters
Maximum Securing Load (MSL): Between 5 and 6 tons
Roll Lashing
Considered to be the base form of all lashing material made from
synthetic fiber
Features: Equipped with hooks at both ends
Securing Process: Produced using a ratchet
Typical Length: Approximately 10 meters
Maximum Securing Load (MSL): About 2 tons (20 kN)
Web Lashing
Roll Lashing FEATURES
Uses -elephant foot hooks-, or -slings- at the ends
A lighter variant of web lashing used for securing delicate cargoes
such as luxury cars, vans or other light vehicles
Securing Process: Attach hooks to securing points, then tighten by
pulling the loose end. Close the handle after tightening
Typical Length: 3 meters
Maximum Securing Load (MSL): 1 ton (10 kN)
Car Lashing
For vehicles not equipped
with appropriate lashing
points, may be
used, typically by
attaching them to the rims
of the wheels.
Slings
Lashing to be used for the heaviest possible cargo load such as
heavy vehicles, machineries, project cargo, and steel products
Features: Uses elephant foot hooks
Securing Process: Achieved using a tensioning lever or
turnbuckle. May be used with the tensioning lever to increase
pre-tension
Typical Length: (varies from cargo to cargo)
Maximum Securing Load (MSL): 50% of MBL
Chain Lashing
Chain Lashing feature
uses elephant foot hooks
tensioning lever or
turnbuckle
used to lash cargo or vehicles to the
deck of a vessel in combination with a
shackle and lashing chain or can be
attached to a chain turnbuckle to
create a lashing system
elephant foot
To keep vehicles from moving,
Ideally, these should be positioned
under the vehicle’s unbraked axle
Chocks
are specifically used for
vehicles stored across the width of the
ship or on inclined ramps
Chocks
Used to distribute the
pressure of securing
equipment over a wider area
Corner Protectors
Used to prevent lashing
equipment (particularly web
lashings) from getting
damaged by sharp edges
Corner Protectors
highest load to
which cargo securing equipment may
safely be subjected
Maximum Securing Load (MSL):
Also referred to as Lashing
Capacity(LC
indicates the tested minimum breaking
strain of the equipment in unused
condition
Minimum Break Load (MBL)
Also referred to as Break Load (BL)
are sometimes
manufactured with stripes of thread
in contrasting colors, corresponding
to the MBL by one ton per stripe
Web lashings
It is “an adjustable device consisting of
three primary components: a body, a
right-hand threaded end fitting, and a
left-hand threaded end fitting”
(American, 2014)
Turnbuckles
a piece of hardware used to eliminate
slack and adjust tension in a rope,
cable, or other tensioning system
Turnbuckles
also known as pipe bodies—encase
the threads in a closed frame to
create a slimmer profile that fits in
tighter spaces
Closed body turnbuckles
more traditional type where the
threads are visible through the
body frame
Open body turnbuckle
is used to create temporary connections
and are easy to quickly connect and disconnect.
should never be used in connections where tension could
unexpectedly release
Hook end
consists of a jaw and bolt secured together by a nut or a
pin.
Jaw end
used to connect to components that cannot be opened,
such as an eye bolt
Jaw end
a closed loop that can be connected to a shackle or quick
link
Eye end
