1. the work horses of the construction industry crawler (tracklaying) doz-
ers
2. an advantage of a wheel-type dozer as compared with higher speed
a crawler dozer is
3. they are designed to provide high drawbar pull and crawler dozer
tractive effort
4. the crawler dozer exerts adding to low ground-bearing pres-
its versatility sure
5. dozer tractors equipped with a blade are standard excavating
equipment for
6. dozers equipped with special clearing blades are used land clearing
for
7. dozers equipped with push blades or blocks are used assisting scrapers to load
for
8. a dozer can have a rear mounted ripper for loosing and breaking up
rock
9. 2 examples of dozer blades: tilted
angled
10. ideal production values (lcy/hr) are based on the fol- 100% eflciency
lowing conditions: Power-shift machines
11. ideal production values (lcy/hr) are based on the fol- Coeflcient of traction:

12. ideal production can be based on hydraulic controlled
blades
13. when a machine pushes material within a narrow slot dozing
"slot" created by previous passes minimizing side
spillage and maximizing the amount of material
moved per pass
14. more focused, efficient method for moving material slot dozing
by creating a contained path
15. involves pushing material alongside another machine side-by-side dozing
often used for larger volumes but with less efficiency
due to potential material loss to the sides
16. broader approach with potentially more material loss side-by-side dozing
17. dozer: haul, than short
less
