The
process of snow removal may be hazardous duty. Removing the
effects of a winter storm in the midst of traffic and physical
hazards is a job that requires highly skilled operators who
must be alert to their surroundings and thoroughly familiar
with their equipment.
Snow
removal equipment, in spite of its rugged appearance, is susceptible
to damage. This damage may seriously affect not only its operating
efficiency, but also the operating safety of the unit. Daily
maintenance or pre-route maintenance is a must. An alert operator
sensitive to the condition and operating characteristics of
his or her vehicle is most important in order to catch small
problems before they manifest themselves as major calamities.
Snow
removal equipment, or any equipment, should not be subjected
to uses for which it was not designed. Example: Do not use
a snow wing as a ditch cleaner or a snowplow as an ice scraper.
a.) Snow wing operation is designed to assist the snowplow
in moving loose snow from the shoulder of a roadway or to
provide additional first pass clearing where conditions permit.
b.) Snowplow operation is designed for wet or dry snow conditions.
The Falls SnowPlow may be tilted forward for a harder scraping
action to assist in the removal of compacted snow.
Extreme
Caution should be used when attempting removal of compacted
snow. The inconsistency of material and the pressure on the
cutting edge may cause the prime mover vehicle to move suddenly
in an unexpected direction. Physical hazards must be avoided.
Obstructions such as curbs, manholes, fire hydrants, bridges,
concrete pillars, and frozen piles of snow and ice may cause
damage to a snow plow or snow wing. Tripping devices and shear
pins are designed to minimize the damages, not to prevent
them.
The
question about safe operating speeds requires a lot of input:
- What
type of road surface is being plowed?
- How
many lanes of traffic?
- What
time of day?
- What
is the weather condition?
- What
is the present condition of the road? Icy? Snow-packed?
- How
much traffic is present?
- What
is the moisture content of the snow?
- What
type of vehicle is being used as the prime mover? Motor
grader? Front end loader? Single axle truck? Tandem axle
truck?
- What
is the experience of the operator?
- What
has been the historical practice?
- What
is the policy of the governing agency in regard to speed
and what is the policy as to how clear the road surface
is to be plowed? Bare pavement?
All
of these questions must be answered to begin to suggest a
safe operating speed. Even if all the data is known and a
reasonable operating range is defined, accidents may still
occur and the process by which such a range was derived will
be questioned.
