In some congested areas, plows pile snow too high
to see around at intersections, and the pile has to be
removed. A wheeled loader is best-suited for this job.
Care must be taken when moving snow piles with a
loader. Fireplugs, electrical and telephone boxes, and
other utilities may be buried in the snow. If you are not

Most snowplows are equipped with a sand spreader,
commonly called a sander. Sand spreaders can be
truck-mounted (fig. 14-42) or towed (fig. 14-43).
Spreading hot sand over ice with conventional sand
spreading equipment (fig. 14-43) is considered to be one
of the most effective ways of producing traction on iced

surfaces. In this operation, the particles of hot sand
embed themselves in the surface and thus resist removal
by traffic and wind.
For best results, the heated sand
should be applied to the iced surface as quickly as
Loose sand, applied with the sand spreader, is also
used to produce traction on iced surfaces. This method
is generally satisfactory, but because the sand is not
firmly bonded to the ice, it is blown off the surface by
wind and traffic. This method is more effective when
applied to surfaces that are wet and when freezing
temperatures are expected.
