EARTH MOVING 
EQUIPMENT
EARTH MOVING EQUIPMENT 
 TRACTOR 
 BULL DOZER 
 SCRAPER 
 RIPPER 
 GRADER
SCRAPER 
•Unique machine for digging and long-distance 
hauling of plough able materials. 
• self-operating machine 
• It is not dependent on other equipment. 
• Wheels of machine cause some compaction. 
• The basic parts of scrapers are the bowl, apron 
and tail gate or ejector.
SCRAPER
BULL DOZER 
The heavy blade attached to the tractor pushes 
the material from one place to another. 
The tractor can be of the crawler or the wheeled 
type. 
Classification of bull dozer 
1. Position of blades 
A. Bull dozers in which the blade perpendicular to the 
direction of movement 
B. Angle dozers in which the blade is set at an angle with the 
direction of movement.
2. Based on mountings 
A. Wheel mounted 
B. Crawler mounted 
3. Based on the control 
A. Cable controlled 
B. Hydraulically controlled
Applications 
Bull dozers are mainly used for the following 
Operations 
1. For spreading the earth fill 
2. For opening up pilot roads through mountainous 
and rocky terrains. 
3. Clearing construction sites. 
4. Maintaining haul roads 
5. Clearing land from the trees and stumps. 
6. back-filling trenches at construction sites by 
dragging the earth from one place to another
Tractor 
Multi-purpose machines used mainly for pulling and pushing 
the other equipment. 
Tractors may be classified as 
a) Crawler type tractor- Used to move bull dozers, scrapers. 
The crawler has a chain by which these tractors can be very 
effective even in the case of loose or muddy soils. The speed 
of this type dose not exceed 12 kmph normally. 
b) Wheel type tractor- The engine is mounted on four wheels. 
The main advantage is higher speed, sometimes exceeding 
50 kmph it is used for long-distance hauling and good roads.
