Ryder's Olson says tire pressure monitoring systems
(TPMS) can also help. They feature temperature and
pressure sensors that provide real-time notifications
of slow leaks to help prevent complete tire failure and
expensive road service.
"High temp[erature] warnings could also be an indication of developing brake or wheel-end component
failures," Olson adds.
Speaking of brakes,
Olson says thorough
inspections are key and
should include:
Ü	Checking inside and
outside of wheel-end
components for signs
of fluid leaks or worn
brake linings
Ü	Checking brake lines
that connect tractor
to trailer, as well as
all lines feeding the
braking components
Ü	Proper lubrication of
all brake components

crimp terminal connectors that have heat-shrink sealing. Finally, never do more than one repair for every
five feet of wire [10 to 20-gauge size]."
The liftgate is another area that needs to be closely
maintained in order to maximize trailer ROI. Olson
says he has recently noticed an increase in battery
failures during high-cycle routes.
"With some fleets, the impact from COVID had


shortened their runtime in a day - to the point that
it was preventing proper charging of liftgate batteries," Olson relates. "After a few days, the battery
would fail. This was not anticipated when initially
spec'ing the trailers. So that means looking at solar
charging and available charging components such as
the refrigeration unit and tractor supply to increase
the daily charging amperage demanded."

Lighting systems can
also create ROI challenges. They are prone
to damage from striking elevated objects
such as tree branches.
Additionally, water is
a common culprit that
fleets need to be especially vigilant about.
