Figure 11-27.-Slot dozing.
Side-by-side dozing (fig. 11-26) and slot dozing
(fig. 11-27) maximize the amount of earth drifted by
reducing or preventing spillage around the outer edges
of the blade.
SIDE-BY-SIDE DOZING. In side-by-side
dozing, two dozers work abreast with blade edges as
close together as possible, preventing spillage around
one blade edge on each dozer. Side-by-side dozing
requires time-consuming maneuvering of the dozers;
therefore, it is impractical for hauls of less than 50 feet
and more than 300 feet.
SLOT DOZING. Slot dozing is done by first
building a pair of windrows with the spillage of several
passes. As shown in figure 11-27, the windrows serve
as barriers to prevent spillage around the dozer blade
ends. Under favorable conditions, slot dozing can
increase production up to 50 percent.
