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.
