side and roof panels — vans
Side and roof panels are critical structural members
of the trailer. Small holes can be patched using an
over- lay panel with blind rivets. Large holes may
require panel replacements. When repairing large
holes or when replacing full panels, use solid rivets of
2117-T4 aluminum for aluminum panels, or solid rivets
of type 302HQ for stainless steel panels.
FIBERGLASS-REINFORCED PLYWOOD (FRP)
FRP panels are of a composite construction where
plywood is overlaid with fiberglass cloth, resins and
gelcoats. It's very important that any cuts or scrapes
through the outer glass coatings be repaired immedi-
ately to protect against water intrusion into the plywood
core. If the plywood core is exposed to moisture for any
period of time delamination and/or rot may occur.
FRP panel connections to rails, front, and rear frame
connections are sealed with a high-grade sealer at the
time of manufacture. As with any coating or sealer, this
sealer may deteriorate due to age and weathering and
rear frame, doors and hardware
REAR FRAME
The rear frame should be inspected at regular intervals
for damage to the frame, doors and hardware from
impacts with loading docks, abutments or other devices
in the loading area. An area of particular concern is
damage to the rear posts at hinge butts. This can cause
binding, door distortion, and eventual failure to the door,
door hinges, or both.
DOORS
Check rear doors for damage or warpage to panels,
frame or hinges. Compression seals should be checked
to see if the seals need to be repaired or replaced to
ensure a tight closure. The seals around vent doors,
should be checked and maintenance performed as
needed. Interior linings or insulated doors should be
checked for damage or loose or missing fasteners and
repaired as required.
Safety equipment in the rear frame area (such as door
hold backs, grab handles, steps, ramps and slip-resist-
ant materials) should be inspected at TPM. If necessary,
they should be repaired or replaced.
HARDWARE
1. Check anti-rack rear door locks for damaged,
distorted, or cracked tubes resulting from impacts.
2. Check operation and engagement of cams
into keepers.
3. Inspect bearing plates for loose or
missing fasteners.
4. Check tamperproof fasteners in gravity
keepers and the top and bottom hinge.

should be inspected and resealed as necessary after 24
months in service.
A Great Dane FRP repair manual is available upon
request.
BONDED ROOF
Your equipment should be directed to your qualified
Great Dane branch or dealer repair shop for proper
repairs. If this is not possible, you should contact Great
Dane for proper repair instructions and information on
necessary bonding materials.
warning
No attempt should be made to repair a bond-in-
place roof bow/roof sheet assembly without
a complete understanding of the design,
materials and the equipment needed to achieve
the proper repair.
5. Check the operation and engagement of the
third-point lock (on some models).
6. On insulated trailers, inspect the interior sealing
surfaces (PVC wedging) to be sure that the thermal
efficiency is maintained. Repair or replace any
components as needed.
OVERHEAD DOORS
If the door becomes difficult or impossible to operate,
have it repaired or adjusted by a qualified mechanic.
1. The door spring is constantly under extreme ten-
sion. Repairs and adjustments, especially to the
door counterbalance assembly, are potentially dan-
gerous and must be performed by qualified service
personnel only.
2. Clear any obstruction from the door tracks and the
base of the mounting angle where the door comes
down to the floor.
3. Perform regular inspection and maintenance on the
following items:
a. Be certain that all nuts and bolts are tight and
secure.
b. Check cables full length and at attachment
points and replace all frayed or otherwise
damaged cable.
c. Check cable drums for tightness against
bearings.
d. Check all rollers for smoothness of operations
and have all sliding or otherwise damaged
rollers replaced.
e. Replace frayed, damaged or severely worn pull
straps.
f.
Check the door lock to be sure that it is free,
and fully operational.
entry and exit
Regardless of who may have manufactured or installed
the access equipment, it has been installed for the
safe entry and exit of persons and/or products. It is
necessary that these items be included in your regular
Trailer Preventive Maintenance (TPM) Program.
These items must be checked for proper safety
operations. Welds and fastener connections must
floor system
The floor system should be inspected regularly so that
the fail-safe rating that was manufactured into the floor
system can be maintained.
warning
Trailer floors can become slippery. Be careful
when walking in or on the trailer. When floors
become slippery, they should be properly
cleaned and degreased, rather than using salt
or other chemicals to increase traction.
TOP FLOOR
Check the top floor for loose or missing screws,
separated lamination or failing floor boards, deformed
crossmembers, rear impact area damage from forklift
traffic, weld separation, or fatigue cracks in aluminum
floors.
Undercoating on wood floors should be checked
periodically and re-undercoated if necessary.
(Every 24 months.)
insulated trailer maintenance
Proper education and knowledge by the operators and
maintenance personnel using refrigerated trailers can be
beneficial in many ways: cleanliness, sanitation, mainte-
nance of reefer exteriors and interiors, lining finishes,
insulation efficiency, operation of doors, and mechanical
refrigeration units. Safety and profitable operation are
closely related, and they are dependent on the normal
operation care and thoroughness of the maintenance.
CLEANING
Steam Method: Live steam does a good job of cleaning
and deodorizing. However, steam is harmful to wood
liners, sealers, and exposed vapor barriers, and it is not
recommended. If steam must be used, a waterproof
sealer should be applied to both sides and all edges to
protect the trailer.
g. Replace broken or damaged hinges.
h. Periodically use a light lubricant (not grease)
on rollers, counterbalance hinges, and lock, as
necessary, to maintain a smooth door operation.
be checked and corrected as necessary. Latches,
hold downs, etc. must be checked and must function
correctly. These items must be kept clean and free
of materials that may cause them to become slippery.
These items must be cleaned and degreased as
necessary for a safe operation.
CROSSMEMBERS
Deformed, twisted, or damaged crossmembers should
be removed and replaced with original equipment.
End-clip crossmember connections to bottom side rails
should be checked for loose, damaged or missing rivets
and the general condition of connections.
CAUTION:
Loose connections will cause prema-
ture failure of the floor system. Loose connections
must be corrected as soon as they are found.
Great Dane should be contacted for fastener replacement
information. If this information is not available, Grade 5
(minimum) bolts and Grade B (minimum) locking type
nuts may be used but must be torqued properly.
Detergents: If detergents are used, they must be mild,
and they must be properly rinsed after application.
All joints should be resealed as required to maintain
a watertight seal.
CAUTION:
Insulated and refrigerated trailers are
designed to transport food and food products.
The vehicle must be clean before loading.
DO NOT transport products or use cleaning
agents in these trailers that could cause
contamination of any food product.
