•FRONT SHOVEL EXCAVATOR
THREE TYPES...

5. POWER SHOVEL EXCAVATOR
 Long-lasting and useful class of earth moving equipment
 Capable of excavating all types of earth except hard rock
 Size of power shovel varies from 0.375-1.05m3
 It may be crawler mounted or wheel mounted shovels

6. 6
Crawler mounted shovel:
Low speed
Effective in unstable soil
Wheel mounted shovel:
Higher speed
Effective only in firm ground

7. Power shovel deponds on:
 Class of material
 Depth of cutting
 Angle of swing
 Job conditions
 Management conditions
 Size of hauling units
 Skill of the operator
 Physical condition of the shovel 7

8. Applications:
 Suitable for close range work
 Capable of digging very hard materials & remove big boulders
 Used in digging in gravel banks , clay pits , digging cuts in road
works , road-side berms etc.

9. BACK HOE SHOVEL EXCAVATOR
 Also known as hoe , back shovel & pull shovel
 Used to excavate below the natural surface on which it rests
 Hoes used to excavate trenches , pits for basemants & grading works
 Used to establish natural slopes

10.  In strom drain and utility work the hoe can perform the
trench excavation and can handle the pipe by eliminating
a second machine
 There are special buckets for everything from light sand
to hard rock digging

12. Applications:
 Suitable for digging below the machine level
 Effectively used to dress or trim the surface avoiding the use of
manual effort for dressing the excavated surface
12

13. FRONT EXCAVATOR
 Used predominately for hard digging above track level
and loading haul units
 Loading of shot rock will be a typical application
 Shovel is capable of developing a high break out force
 The material being excavated should be such that it will
stand with a fairly vertical face
13

14. FRONT SHOVEL EXCAVATOR
 High excavation rate due to unique front shovel and side
tip operation
 Prolec laser system enables excavation to a more
accurate level – resulting in quicker excavation rates
while reducing the chance of over-digging
14

15.  Improved track quality due to the excavation action
(pushing into spoil rather than pulling it back)
 Fewer machine controllers on site meaning less risk and
safer operations

18. Factors afecting shovel excavators are:
 Class of material
 Height of cut
 Angle of swing
 Size of houling units
 Operator skill
 Physical conditions of the shovel
