• Check doors, hinges, lock rods, and holdback
devices for damage or distortion from impact.
• Door seals are subject to wear and damage.
They must be routinely checked and repaired or
replaced to ensure a tight, weatherproof closure
that protects cargo
.
overhead Doors
The trailer overhead door system includes door
panels, tracks, a door-operating assembly, and
locking hardware. Regular inspection of the
overhead door system is important to ensure safe
vehicle operation.
When the overhead door is in operation, the
movement is assisted with the help of a pre-
tensioned spring. When stopped, a properly
counterbalanced door should remain at any given
position. If the door leaves the floor by itself when
the latch is released, the spring tension is wound
too tight. If the door has the tendency to drop when
stopped, it should be inspected and adjusted or
repaired by qualified personnel.
Be sure to read, understand, and comply with all
instructions noted on all labels affixed to the door.
WaRNING:
High-tension springs can cause serious injury
or death. all repairs and adjustments must be
made by trained service personnel.
before operating
• Do not manually operate the door with a broken
counterbalance spring. The door will not be
counterbalanced and will free-fall when opened.
• Inspect all fasteners. Tighten or replace loose
fasteners on the lift handle, lock, pull strap, and
hinges. Inspect the pull strap and replace it if
frayed or damaged.
• Do not tie anything to the pull strap – longer pull
straps are available if required.
During operation
• Check handle movement. Lubricate the handle
with light oil if movement is stiff. Have any worn or
damaged latch/locking assembly parts replaced.
