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.

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.

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
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.

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.

TOP FLOOR

Check the top floor for loose or missing screws,
separated lamination or failing floor boards, deformed
crossmembers, rear impact 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.)

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 or missing rivets and the
general condition of connections.

Great Dane should be contacted for fastener replace-
ment 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.

INSULATED TRAILER MAINTENANCE

Proper education and knowledge by the operators and
maintenance personnel using refrigerated trailers can
be beneficial in many ways: cleanliness, sanitation,
maintenance 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.

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.

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.

CAUTION

Loose connections will cause premature failure
of the floor system. Loose connections must be
corrected as soon as they are found.

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.
