3-2 USING THE LIGHT TOWER
OVERVIEW
Allmand light tower trailers are intended to be used for
job site illumination and electrical power. The diesel
engine drives a generator, which provides power for
the light fixtures and the power outlets. When the lights
are not in use, all of the generator power is available at
the outlets. When all four lights are on, they consume
approximately 4.5 to 5.5 kilowatts (kW) of power
(depending on the rating of the light fixtures equipped
on your light tower), leaving the remainder of the
generator power for the outlets. The amount of power
available depends on the generator with which your
light tower is equipped.
Most controls for the light tower are accessed through
the door on the left rear of the trailer. Access for
inspection and maintenance of the engine, generator,
and other components is through the side doors.
WORK SITE CONSIDERATIONS
Prior to starting and operating the light tower, you must
determine where to place it on the work site. The best
possible light coverage and illumination is attained
when the light tower is located on the same level as the
work area to be illuminated. When placing the light
tower trailer, consideration must be given to overhead
clearance, ground conditions, and wind.
As the operator, it is your responsibiity to ensure that
the light tower trailer is properly positioned on the work
site. Proper placement on the work site will provide for
safe and stable operation of the light tower.
OVERHEAD CLEARANCE
Before positioning the light tower trailer on the work
site, make sure that there are no overhead obstructions
where you intend to place the trailer. If the work site is
in an enclosed area, such as a building, keep in mind
that, when vertical and extended, the light tower mast
requires a minimum of 36 feet (11 m) from ground level
to the top of the light fixture.
Always keep well clear of any overhead power lines or
buss bars.
Keep well clear of any loose cables, ropes, or
obstructions that could interfere with the light tower
mast.
GROUND CONDITIONS
You must place the light tower trailer on a firm, stable
surface that will support the total weight of the trailer,
as well as each of the five stabilizer jacks. Make sure that
the surface where the light tower is to be positioned has
enough area to allow full extension of all outriggers. We
recommend that the trailer be positioned on a level
surface, however, if it is necessary for the trailer to
positioned on a grade, do not exceed a grade of 5% (2.9°
incline) in any direction. Grades greater than 5% may
exceed the extension limits of the stabilizer jacks,
preventing contact of one or more of the jacks with the
ground.
WIND
When the light tower is vertical and extended, wind can
exert a powerful force on the light tower trailer. When
you position the trailer on the work site, be aware of
ground obstructions such as buildings, structures, or
trees that may direct wind toward the light tower or
cause buffeting around the light tower.
With the outriggers and stabilizer jacks properly
deployed on stable ground, and the light tower trailer
properly leveled, the light tower is designed to
withstand sustained winds of 53 mph (85 km/h)
without the danger of rollover.
DANGER
Contact with overhead electrical
wires will result in death or serious
injury. Always maintain a minimum
distance of 45 feet (14 m) from
overhead wires to the light tower.
WARNING
Raising the light tower without properly positioning
the outriggers and stabilizer jacks first could cause
machine rollover, resulting in death or serious injury.
Always deploy the outriggers and stabilizer jacks on a
firm, level, and stabile surface before raising the light
tower.
