W
inter is coming, and storm response
crews are preparing. When ice and
snow hang on the power lines and
knock out electrical service, utility
linemen have to be ready to go at a
moment’s notice. One of the most critical tools they bring
along to restore your power is a bucket truck. Operating in
freezing temperatures means the equipment has to stand
up to harsh elements. Sub-zero temperatures, moisture, and
slippery roads are only a few of the challenges bucket truck
crews may face. Many of the problems bucket trucks can
experience in the winter are associated with the chassis: the
battery, engine oil, spark plugs, thermostats, and door locks.
Additional precaution should be taken when operating a
bucket truck in cold weather.
We are always glad to see those heroes who wear hard hats
when they arrive to restore power, phone, and cable TV. Let’s
look at a few of the things operators need to consider check-
ing on their equipment in advance, before loading up trucks
and heading out to restore the electricity.
When preparing to leave for a lengthy trip, check these
items, to avoid equipment trouble:
Hydraulic Equipment
- Hydraulic unit and used bucket
truck accessories that should be monitored during winter
temperatures include the hydraulic system, control panels,
bearings, lines, and fittings. Many units have electronic
“over-stow” switches that can remain engaged when ice is
present and prevent the boom from functioning properly. Hot
water and a rubber mallet can help free up the switch and
get the boom back in action. Insure proper maintenance and
lubrication of your bucket truck to keep it in top condition
for years to come.
Winch Lines and Cables
- Inspect the cables and ropes
that are regularly used to hoist materials into place, looking
for damaged areas. It is better to find and replace any dam-
aged lines in the shop rather than out in the cold weather.
Engine Fluid Levels
- Inspect each fluid to ensure it is at
the proper level, and consider carrying along extra, if permis-
sible. Remember, there are hydraulic system fluids that power
the unit, as well as the typical truck chassis fluids, including
windshield washer fluid, coolant, transmission fluid, differen-
tial fluid, etc.
Truck Batteries
- Most batteries are rated to a specific
sub-zero temperature. Know the temperature for which the
battery is rated and be prepared to take additional precau-
tions if traveling in temperatures below that limit. Make sure
the battery is in proper working condition with clean, non-
corroded terminals to protect against any starting problems.
Tire Pressure
- Before taking a trip, tires need to be
checked for proper inflation. Changes in temperature cause
the tire pressure to increase and decrease. Check with your
tire manufacturer to get the recommended operating pressure
levels for the conditions in which you will be driving. Both
under-inflated and over-inflated tires will affect handling abil-
ity and fuel efficiency.
Windshield Wipers
- Clear visibility is very important
during colder weather. Check wiper blades for damage and
replace them with new blades if needed. Remember that the
windshield washer fluid needs to have de-icing capability.
This will help increase your visibility when precipitation is
falling as well as prevent the wipers from freezing during
sub-zero weather.
Vehicle Body
- Ice, rocks, and road salt can damage the
exterior paint of the bucket truck, which can lead to corro-
sion. A coat of “winter wax” can help preserve the paint.
Wash the bucket truck frequently during the winter to re-
move any corrosive materials that can get stuck on the truck
from roadways.
Door Lock Lubrication
- Locks can freeze during frigid
temperatures. Lubricating the hood latch, door, and any other
locks is necessary to help prevent sticking. Apply lubricants
to prevent ice forming and to keep the locks working freely.
Always follow the operators and maintenance procedures
as directed by the equipment manufacturer.
