COMPREHENSIVE QUESTIONS AND ANSWERS SET

✔✔Non-structural Component - Roof bow - ✔✔Roof bows are lateral, non-structural
members attached to the top side rails designed to support the underside of the roof
panel. Aluminum open-end containers use permanent roof bows to support their rigid
roof panel while open-top containers use removable roof bows to facilitate cargo loading
through the top of the container.
✔✔Non-structural Component - Roof reinforcement plates - ✔✔Roof reinforcement
plates are metal plates designed to protect the roof from damage. Striker plates are
attached to each corner of the roof panel, protecting it from misaligned handling
equipment. The sling pad, installed in the center of the roof panel, protects it from
lowered handling equipment.
✔✔Non-structural Component - Steps - ✔✔Folding steps are found on some ISO
shelters and are used to gain access to the roof. They must be folded up prior to
transporting the shelter.
✔✔Open-top Container Roof Components - Removable roof bow - ✔✔Removable roof
bows are lateral members placed between the top rails of open-top containers. They
support the removable cover (tarp) when in place but can be removed to facilitate the
loading of cargo through the top of the container.
✔✔Open-top Container Roof Components - Tarp - ✔✔The tarp (or tarpaulin) is a
flexible, waterproof fabric used to cover the top of an open-top container. This cover is
referred to as a "tilt" in some countries.
✔✔Open-top Container Roof Components - TIR cable - ✔✔A TIR cable is a plastic-
sheathed cable threaded through the welded loops of an open-top container designed
to secure the tarp to the container. TIR stands for "Transport international de
,Marchandises par la Route," and refers to an international customs agreement
concerning the transport of goods.
✔✔Non-structural Component - Flooring - ✔✔Container flooring is constructed of
laminated wood planks, plywood sheets, welded steel or aluminum sheets, sandwich
panels, or a combination of metal and wood screwed or bolted to the cross members,
forming a load-bearing surface for cargo.
✔✔Non-structural Component - Threshold plate - ✔✔A threshold plate, also called a
crash plate, is a metal plate mounted forward of the door sill designed to protect the
entrance area of the container floor from cargo-handling activities.
✔✔Non-structural Component - Door panel - ✔✔The door panel consists of corrugated
or flat sheet steel, plymetal, aluminum sheet, sandwich panel, or FRP panel. It's hinged
on one side and has locking mechanisms, seals, and other necessary hardware
mounted to it. Each container has an inner door that closes first and an outer door that
closes over the inner door.
✔✔Non-structural Component - J-Bar - ✔✔The J-Bar is a portion of the exterior edge of
the door frame corner that encircles and supports the door hinges. Although the J-Bar
and the corner post are manufactured as one piece, they are inspected and repaired as
separate components. Corner post defects are much more critical than J-Bar defects.
✔✔Non-structural Component - Hinge and hinge pin - ✔✔The hinge assembly is
comprised of a blade permanently joined to the door and a lug integrated into the corner
post structure. They are joined together by the hinge pin, allowing the door to pivot open
and closed. Hinge pins are often welded on the end to prevent thieves from removing
the doors.
✔✔Non-structural Component - Locking bar and mount - ✔✔The locking bar is a vertical
rod mounted to each door panel with cam locks fitted at each end. When rotated, it
engages the cam retainers on the doorway frame to lock the doors. On some open-top
containers with ramp type doors, this rod is horizontal.
✔✔Non-structural Component - Cam and retainer - ✔✔The cam is an offset fitting on
each end of the locking bar that engages the cam retainer to lock the door. One cam
retainer is attached to the door sill and header for each locking bar and cam.
✔✔Non-structural Component - Door locking handle and retainer - ✔✔The door locking
handle is attached to the door locking bar; rotating it will open or close the doors.
, The door locking handle retainer, when engaged, locks the door locking handle in the
closed position. It also provides a means to place a lock and/or security seal on the
doors.
✔✔Non-structural Component - Anti-rack hardware - ✔✔Collectively, the locking bars,
locking bar mounting brackets, cams, cam retainers, door locking bars, and door locking
bar retainers are referred to as anti-rack hardware. Their purpose, in addition to keeping
the doors closed, is to strengthen the open end of the container.
✔✔Non-structural Component - Customs catch - ✔✔A customs catch is a rod or plate
attached to the center edge of the outer door to prevent the inner door from opening
when the outer door is closed. It is used on door assemblies that are not designed with
an overlapping edge on the outer door.
✔✔Non-structural Component - High-security hasp - ✔✔A high-security hasp is a heavy
steel enclosure surrounding the door lock hasp designed to prevent someone from
cutting the lock off with a bolt cutter or other device. It's used on containers transporting
dangerous material or cargo requiring additional security.
✔✔Non-structural Component - Door seal gasket - ✔✔The door seal is a flexible plastic
or rubber gasket attached to the door edges with rivets and adhesive. It provides a
waterproof seal between the doors and door frame.
✔✔Non-structural Component - Rain gutter - ✔✔The rain gutter is a channel attached to
the door header on some containers to divert water away from the doorway.
✔✔Non-structural Component - Three-point latch - ✔✔A three-point latch is a latch
system used on tactical shelter/mobile facility doors to secure the door using three roller
cams. This provides additional security and allows the door to be latched from the
inside.
✔✔Non-structural Component - Chain and foot bolts - ✔✔A chain bolt is a spring-loaded
bolt used to lock the upper portion of the double doors on a tactical shelter/mobile
facility. A foot bolt is a spring-loaded bolt used to lock the lower portion of the double
doors on a tactical shelter/mobile facility.
✔✔Non-structural Component - Door hold backs - ✔✔A door hold back is a small hook
or loop attached to the side of a container to hold the door in the fully open position. It
prevents the doors from blowing closed on personnel performing container inspections
or maintenance. Not all containers have door holders.
✔✔Cargo Restraint - Restraints - ✔✔MILVAN containers have an integrated cargo
restraint system consisting of eight slotted horizontal rails on the container walls, a pair
of slotted vertical rails on the door ends, and 25 movable shoring beams that lock into
the rail slots. These components are deigned to stay with the container at all times.
