capacities
 DEWATERING :VACCUM FILTERS,SLUDGE
LAGGONS ,DRYING BEDS ,FILTERS PRESSES

7.  Excavation
 Digging of large quantities of earth work
 Hauling
 Placement
 Compaction
 Dozing
 Grading
 Placing of concrte

8.  POWER SHOVEL
 BACKHOE
 BULL DOZERS
 ROLLERS
 DUMPTRCUKS

12.  To excavate the earth and to load the trucks
 Capable of excavating all types of earth work
except hard rock
 Size varies from 0.375 cu.m to 5 cu.m
 Basic parts of the shovel are track
system,cabin,cables ,rack, boom, boom point
sheaves .
 For excavating blasted rocks, large size dipper will
easily handle bigger sizes.

13.  Capable of digging very hard materials
 Can remove big sized boulders
 It is used in various jobs such as digging in gravel banks,
clay pits ,digging cuts,road side berms

14.  Class of material
 Depth of cutting
 Angle of swing
 Job condition
 Management condition
 Size of hauling equipment
 Skill of the operator
 Physical condition of the shovel

17.  Also known as back shovel and pull shovel
 It is used to excavate below the natural surface on
which it rests
 Generally used to excavate trenches ,pits for
basements and also grading ,precise control of
depths
 The basic parts are boom, stick, bucket and
bucket drum, cabin etc..

18.  Backhoe loaders are very common and can be
used for a wide variety of tasks :
 construction, small demolitions, light
transportation of Building materials , powering
building equipment, digging holes, landscaping,
breaking asphalt, and paving roads. Often, the
backhoe bucket can also be replaced with
powered attachments such as
a breaker, grapple, auger

19.  It is most suitable for trenches ,footings and
basements,etc..
 It can be efficiently trim the surface avoiding the
use of manual effort for dressing the excavated
surfaces

22.  The heavy blade attached to tractor pushes the
material from one place to another place
 The tractor can be wheeled type or crawler type
 For spreading the earth fill
 For opening the pilot roads thorough
mountainous and rocky terrains

23.  Mainting and removing dirt and dust on highway roads
 Clearing land from the trees and stumps
 Back filling trenches at sites dragging the earth from one
place to another
 Clearing construction sites

24. is the process in which a stress applied to a
soil causes densification as air is displaced
from the pores between the soil grains.

25.  Smooth wheel rollers
 Sheep-foot rollers
 Pneumatic type rollers

27.  It also known plain roller
 Weighing from 5 to 15 tones
 Used for ordinary rolling work where deep
compaction is not required
 These rollers may have one front and two rear
wheels
 The rear wheels being usually larger in diameter

30.  For compacting earth work in embankments and
canals where deep compaction into the layer of
the earth is required
 These gives the best results in compaction
 The sheep-foot rollers weigh more than 15 tones
 Travel at a speed of 25kmph
 Kneading action compacts bottom to top layer
 These rollers are effective in compacting granular
soils such as sand ,gravel and gravel stones
 Self propelled type

32.  It consists of base or platform mounted between
the two axles
 The rear of which has one more wheel than the
front
 Most suitable for fine grained soils and well
graded sands
 Majorly used in asphalt roads

33.  The equipment used for the transportation of
materials are known as hauling equipment
 Haulers may operate on roadways or railways
 It involve :Transportation of building materials
 B)carriage and disposal of earthwork
 C) haulage of heavy equipment

34.  They are classified on the basis of method of
dumping the load
 a) dump trucks
 i) side trucks
 ii)bottom dump trucks
 B) Dumpers

35.  These are used for the earth moving purpose
 The selection of the type of dump trucks for a
specific job depend on the job condition
 Side trucks : these are heavy duty trucks with
strongly built body which is hinged on the truck
chassis at the rear end and one side respectively,
and can be fitted to the rear in the case of rear
dump and to the hinged side in case of the side
dump, through the action of hydraulic jacks
 These trucks are suitable for use in hauling wet
clay, sand, gravel, quarry rocks

38. These are similar to semi-trailers in which their front is
supported on the rear of the hauling tractor and their
rear is resting on their own wheels.
•The body of the truck remains in the same position
and the discharge of the material takes place through
its bottom after opening of two longitudinal gates.
•The gates are hinged to the side of the body.
•These trucks are suitable for use in hauling free flowing
material, such as, sand, gravel, dry earth, hard clay
etc.

41.  Dumpers :
 High speed pneumatic wheeled trucks
 Short chassis
 Strong bodies
 Loading, hauling and dumping is done very fast
as compared to other equipment
 Suitable for short hauls on rough roads
 Specially where a shuttle movement is required
