The document discusses three types of shovel excavators: power shovel excavators, backhoe shovel excavators, and front shovel excavators. Power shovel excavators come in various sizes and can be crawler or wheel mounted. They are useful for excavating different soil types except hard rock. Backhoe shovel excavators are also known as hoes, and are used for excavating below the machine, such as for trenches, basements, and grading work. Front shovel excavators are predominantly used for hard digging above track level and loading haul units. The document provides details on the applications and operation of each type of shovel excavator.

4 POWER SHOVEL EXCAVATORS BACK HOE SHOVEL EXCAVATOR FRONT SHOVEL EXCAVATOR THREE TYPES...
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 5
6 Crawler mounted shovel: Low speed Effective in unstable soil Wheel mounted shovel: Higher speed Effective only in firm ground
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
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. 8
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 9
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 10
Parts of a back hoe excavator 11
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
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
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
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 15
