7.5.1 Introduction. Equipment at solid waste landfills should be selecte
in relation to the following parameters:
a) Waste quantities and types to be handled, including peak waste
quantities and projected future waste quantities.
b) Daily and seasonal variations.
c) Soil excavation, haul, and cover application, including type
and quantity of onsite soils and haul distance.
d) Time requirement for waste covering and soil compaction.
e) Site conditions, including clearing and grubbing requirements,
topography, and climate.
f) Auxiliary functions, including road construction and
maintenance, construction and maintenance of drainage facilities, assista
with vehicle unloading, and movement of other materials or equipment at t
g) Standby or backup equipment needs.
h) Maintenance requirements, including maintenance history and
record at other sites, and availability of parts or of manufacturers loca
skilled maintenance personnel.
i) Operator comfort.
7.5.2 Equipment Types and Characteristics. Figure 25 illustrates the
major types of earthmoving and compaction equipment commonly found in
landfill sites. In general, sanitary landfills sized for Navy shore
installations would require one or two of the equipment units discussed
22.214.171.124 Track Machines. As a result of their versatility, track machine
are one of the most commonly used machines at solid waste landfills. The
are two types: dozers and loaders. Other common names for them are
bulldozers, crawler dozers, track dozers, track loaders, crawler loaders,
front-end loaders, and bullclams; trade names are also used. They all ha
good flotation and traction capabilities because their self-laying tracks
provide large ground contact areas. Track machines are excellent for
excavation work and moving over unstable surfaces, but they can only oper
at about 3 to 4 miles (5 to 6 kilometers) per hour, in forward or reverse
The track dozer is excellent for grading and can be economically used
for spreading waste or earth over distances of up to 300 feet (91 meters)
It is usually fitted with a straight dozer blade for earthwork; however,
solid waste, it should be equipped with a U-shaped blade that has been
fitted with a top extension (trash or landfill blade) to push more solid
Waste densities achieved with a track dozer generally range from 800
1,000 pounds per cubic yard (475 to 600 kilograms per cubic meter) or
greater, depending on the solid waste composition and skill of the operat
The track loader is able to spread less solid waste than the track dozer;
however, the track loader is an excellent excavator and can carry soil
(economically) as much as 300 feet (91 meters).
