DOZER:

It is a large powerful tractor with a large blade in front flattens areas of ground.

DEFINITION

TYPES OF DOZERS

Wheel Dozer Straight Dozer (Straight Blade) Angling Dozer Semi-U Dozer U-Blade Dozer (Universal Blade)

OTHER COMMON NAMES FOR DOZERS:×Bull Dozer×Crawler 

WHEEL DOZERS are essentially tractors outfitted with dozer blades or push blocks. Used for clearing and grading land, wheel dozers are frequently used in mining applications and reclamation jobs.

STRAIGHT BLADES can be made very strong, abrasion resistant and puncture resistant for moving large, sharp and abrasive objects

ANGLING DOZER IS A BULLDOZER WITH A BLADE WHICH CAN BE PIVOTED ON A VERTICAL CENTER PIN SO AS TO

CAST ITS LOAD TO EITHER SIDE.

Semi-U Dozer

U-BLADE DOZER (UNIVERSAL BLADE)

OTHER COMMON NAMES FOR DOZERS:

Bull Dozer

Crawler 

USES OF DOZERS

Land clearing Dozing (pushing materials) Ripping Towing other pieces of

construction equipment, Assisting scrapers in loading.

THE BIGGEST EARTH MOVER IN WORLD

ABOUT EARTH MOVER(V CAT D8R)

This is the largest earth mover in the world which was built by the German company,Krupp.

It is seen above crossing a Federal highway in Germany on the way to its destination, an open-pit coal mine.

It is actually cheaper to move the large excavator than to try to reconstruct or reassemble the earth mover on site.

SPECIFICATIONS:

The mover stands 311 feet tall and 705 feet long.(height is 24 storied building)

It weighs over 45,500 tons Cost $100 million to build Took 5 years to design and

manufacture 5 years to assemble. Requires 5 people to operate it.

The Bucket Wheel is over 70 feet in diameter with 20 buckets, each of which can hold over 530 cubic feet of material.

A 6-foot man can stand up inside one of the buckets.

It moves on 12 crawlers (each is 12 feet wide, 8′ high and 46 feet long).

There are 8 crawlers in front and 4 in back. It has a maximum speed of 1 mile in 3 hours (1/3 mile/hour).

It can remove over 76,455 cubic meters each day. (100,000 large dump trucks at 40yds. each)

CONCLUSION

THIS IS THE BIGGEST MECHINE IN THE WORLD EVER SEEN BEFORE FOR THE PROCESS OF EXCAVATION OF EARTH
