INTERMODAL DRY CARGO CNTR EVALUATION
TEST QUESTIONS AND ANSWERS SET A+
✔✔Steel End-opening Container - MILVAN - ✔✔A MILVAN, or MILSPEC VAN, is a
specific type of steel end-opening container. It's a military-owned intermodal freight
container conforming to MIL-C-52661 and ISO-standard 1496 Series 1 specifications.
Unlike standard end-opening containers, MILVANs have a mechanical restraint system
built into their inner structure, and they lack forklift pockets.
MILVANS are being phased out in favor of containers requiring fewer parts and less
maintenance.
✔✔Side-opening Containers - ✔✔Side-opening containers allow easier loading and
unloading of large bulky stock, such as bombs. They are similar to end-opening
containers except for their door placement and deeper profile on their bottom side rails.
Side-opening containers come in two-door or four-door configurations and may or may
not have doors on their ends.
✔✔Open-top Containers - ✔✔Open-top containers allow room for larger, bulkier items.
Instead of a rigid roof, they use a removable canvas or reinforced vinyl tarp supported
by portable roof bows. Some have an end door that opens downward to function as a
loading ramp.
Open-top containers heights vary:
Half high (4'3")
Two-thirds high (5'8")
Full high (8'6")
,✔✔Flatracks - ✔✔Flatracks are used for large, heavy cargo that cannot be loaded into a
container with fixed sides or walls. They are similar in size and shape to typical steel
"box" containers, but they lack a roof and side walls.
These containers are being phased out and replaced with container roll-in/roll-out
platforms (CROPs).
✔✔Primary Structural Components - Corner Fitting - ✔✔Corner fittings are standardized
fittings located at the eight corners
of the container. They provide a means of handling, stacking and securing the
container. A container must have corner fittings to meet CSC standards.
✔✔Primary Structural Components - Corner Post - ✔✔Corner posts are vertical
structural members located at the four corners of the container attached to the upper
and lower corner fittings.
✔✔Primary Structural Components - Top side rail - ✔✔Top side rails are longitudinal
structural members located at the top edge of each side of the container between the
corner fittings and end frames. They provide a means for securing the roof panels to the
container.
✔✔Primary Structural Components - Bottom side rail - ✔✔Bottom side rails are
longitudinal structural members located at the bottom edge of each side of the container
between the corner fittings to form part of the understructure. They provide a means for
securing the floor cross members to the container.
✔✔Primary Structural Components - Top end rail - ✔✔Top end rails are lateral
structural members located at the top edge of the front end (opposite the door end) of
the container between the corner fittings.
✔✔Primary Structural Components - Bottom end rail - ✔✔Bottom end rails are lateral
structural members located at the bottom edge of the front end of the container between
the corner fittings.
✔✔Primary Structural Components - Door header - ✔✔The door header is a lateral
structural member located over the door opening between the corner fittings in the door
end frame. It provides structural integrity and a means of securing the top door cams,
allowing the doors to be secured.
✔✔Primary Structural Components - Door sill - ✔✔The door sill is a lateral structural
member located at the bottom of the door opening between the corner fittings in the
, door end frame. It provides structural integrity and a means of securing the bottom door
cams, allowing the doors to be secured.
✔✔End Frame Structural Components - Rear end frame - ✔✔The rear end frame is a
structural assembly at the rear (door end) of the container consisting of the door sill and
header joined at the rear corner fittings to the rear corner posts to form the door
opening.
✔✔End Frame Structural Components - Front end frame - ✔✔The front end frame is a
structural assembly at the front end (opposite the door end) of the container consisting
of top and bottom end rails joined at the front corner fittings to the front corner posts.
✔✔Understructure Components - Crossmembers - ✔✔The crossmembers are lateral
structural members attached to the bottom side rails, designed to support the container
floor and provide floor strength and rigidity.
✔✔Understructure Components - Forklift pocket - ✔✔Forklift pockets are reinforced
tunnels situated transversely across the understructure allowing a container to be
handled by material handling equipment (MHE).
(MILVAN containers do not have forklift pockets.)
✔✔Understructure Components - Forklift pocket strap - ✔✔The forklift pocket strap is a
plate welded to the bottom of each forklift pocket to help secure the forklift forks while
transporting the container.
✔✔Understructure Components - Gooseneck tunnel - ✔✔The gooseneck tunnel is a
recessed area in the forward portion of the understructure to accommodate transport by
a gooseneck chassis (a style of flatbed trailer used to transport ISO containers on land).
This feature is more common in forty foot and longer containers.
✔✔Non-structural Component - Wall panel - ✔✔A wall panel is corrugated or flat sheet
steel, aluminum sheet, FRP, foam and beam, or aluminum honeycomb material. It
forms a side or end wall, protecting cargo from the elements and providing structural
rigidity to the container. There are many variations of corrugated wall panels, depending
on material and construction.
✔✔Non-structural Component - Wall post - ✔✔A wall post is an intermediate vertical
beam riveted or welded to a wall panel, providing rigidity and strength to the wall.
✔✔Non-structural Component - Marking panel - ✔✔A marking panel is a portion of a
wall or door panel with a flat surface, designed to display container markings and
placards.
