Transit Cases
Transit cases are extremely durable cases which are used to transport
sensitive electronic, scientific or military equipment across rough terrains.
Although transit cases come in a wide variety of standard and custom
configurations designed by different manufacturers, they are classified by
their hard, waterproof outer shell and their shock-absorbing interiors.
Protection from shock and vibration as well as from elements such as moisture,
salt spray, dust and water immersion are essential functions for transit cases,
which may face rugged environmental conditions in various military, business
and civilian travels.
Most transit cases were designed originally as military
transport cases, as the military frequently transports highly sensitive
technical equipment across jarring, dusty or wet environments. Many modern explorers,
journalists, photographers, industrial manufacturers, scientists and medical
personnel are commonly faced with similarly harsh travels, during which keeping
sensitive equipment working properly is essential. Transit cases are manufactured
to transport electronic modules, computer components, laptops, satellites,
scientific equipment, photo equipment, sensitive military equipment and many
other parts and equipment which require sensitive handling.
Transit cases are fabricated from fiberglass
reinforced thermoset, fiberglass reinforced polyester (FRP), carbon fiber,
rotationally molded polyethylene or LLDPE with hinges, reinforcements and
hardware made out of either the same materials or aluminum extrusions. Many
transit cases are reinforced along seams and edges with aluminum extrusions,
but not all; nearly all fiberglass, carbon fiber or rotomolded cases contain
custom-cut foam inserts to protect contents from jarring and vibration. These
types of cases also come with 100% waterproof seals.
The other common category of transit cases is the rackmount
transit case; this case is usually paneled with FRP and reinforced with extruded aluminum
and aluminum or steel hardware. Rackmount cases are unique in design in that they
do not usually require foam inserts; instead, interiors are equipped with
elastomeric shock mounts attached to an internal frame of aluminum channels.
This interior aluminum frame holds equipment secure, while the frame's shock
mounts protect the frame and equipment. As with typical foam-filled rotomolded
transit cases, rackmount transit cases are impervious to water, moisture, dust
and dirt, and may protect equipment as sensitive as multi million dollar
satellites.
