This Presentation is about Construction Equipment which are required for various construction works like site clearing, excavation, transportation, spreading, watering & compaction.

2. EARTHWORKS
The moving or processing a parts of earth surface involving
quantity of soil or unformed rock.

3. EARTHWORK MACHINERY

4. EXCAVATION EQUIPMENTS

5. Bull Dozer
(earth clearing equipment)
• Best for shallow excavation
work
• Can hauling the earth for
relatively short distances
• Versatile machine for many
construction projects
• Used for clearing site
• Opening up pilot roads
• Moving earth for short haul
distances of about 100m
• For spreading & excavation of
earth
• Several other jobs

6. Scraper
(earth moving equipment)
• Self-operating
• Can dig, haul & discharge
the material in uniformly
thick layer
• Can also haul the earth for
long distance up to 1500m
• Struck Capacity of scraper
is ideal for highway works
• Not capable of digging very
stiff material
• Can also combined with
dozer

7. Power Shovel
(earth excavating equipment)
• Excavate earth of all classes
except rocks
• Effectively operate from
lower level where it stands
& when the depth of the
face to be excavating is not
too shallow.

8. Dragline
(soft earth excavating equipment)
• Used to excavating soft
earth & to deposit earth in
nearby banks or to load
into wagons.
• Can operate on natural
ground while excavating
from a pit with the bucket;
not necessarily to go into
the pit (as in case of power
shovel)

9. Clam shell
(excavating equipment-except for
stiff earth)
• Buckets of two halves or
shells
• May be attached to shovel
or a drag line
• Open calm-shell bucket is
thrown on the top of the
loose material to be dug as
bucket is lifted, the two
halves close entrapping the
material in to the bucket

10. Hoe
(stiff excavating equipment)
• Excavating equipment of
power shovel family
• Capable of having precise
control of depth
• Can exert high tooth
pressures
• Excavate below the natural
surface where machine is
stationed
