EARTH MOVING

EQUIPMENTS



EARTH MOVING EQUIPMENTS

EARTH MOVING EQUIPMENTS IS USED IN THE CONSTRUCTIONINDUSTRY TO :• TO SHIFT AMOUNTS OF EARTH• TO DIG FOUNDATIONS AND LANDSCAPE AREAS

TYPES OF EARTH MOVING EQUIPMENTS INCLUDE ..• POWER SHOVELS• BACKHOE• SCRAPERS• BULLDOZERS• TRATOR• DUMPERS• GRADERS• TRENCHERS• LOADERS

"re#$hers



• TRENCHERS ARE SIMILAR TO E;CAVATORS IN THE EARTH3BREAKING SOIL AND ROCK3 AND REMOVE IT FROM THEGROUND.

• TRENCHERS DIFFER FROM THE E;CAVATORS 3 IN THAT THESOIL IS REMOVED IN ONE CONTINOUS MOVEMENT.



USESUSED FOR DIGGING TRENCHES FOR PIPES%



lo!ers



•A LOADER IS A HEAVY EQUIPMENT MACHINE OFTEN USEDIN CONSTRUCTION3 PRIMARILY USED TO LOAD MATERIAL

<SUCH AS ASPHALT3 DEMOLITION DEBRIS3 DIRT3 SNOW3FEED3 GRAVEL3 LOGS3 RAW MATERIAL3 ROCK3 SAND3 ANDWOODCHIPS= INTO OR ONTO ANOTHER TYPE OF MACHINERY<SUCH AS A DUMP TRUCK3 CONVEYOR BELT3 FEED6HOPPER3OR RAILCAR=.



•A SKID LOADER OR SKID STEER LOADER IS A SMALL RIGID

FRAME3 ENGINE6POWERED MACHINE WITH LIFT ARMS USED TOATTACH A WIDE VARIETY OF LABOR > SAVING TOOLS ORATTCHMENTS.• THOUGH SOMETIMES THEY ARE EQUIPPED WITH TRACKS3 SKI6STEER LOADERS ARE TYPICALLY FOUR6WHEEL VEHICLES WITH THE WHEELS MECHANICALLY LOCKED IN SYNCHRONIZATION ON

EACH SIDE3 AND THE LEFT6SIDE DRIVE WHEELS CAN BE DRIVENINDEPENDENTLY OF THE RIGHT6SIDE DRIVE WHEELS.

SKI STEER LOAERS



•A CRAWLER LOADER COMBINES THE STABILITY OF THECRAWLER TRACTOR WITH THE ABILITIES OF A WHEEL

LOADER.•HOWEVER3 TO CONSTRUCT A RELIABLE CRAWLERLOADER IT REQUIRES MORE THAN SIMPLY ATTACHING ALOADER BUCKET ONTO A CRAWLER TRACTOR. IT MUSTBE DESIGNED WITH ITS SPECIFIC PURPOSE IN MIND TOENSURE IT HAS THESTRENGHT TO WITHSTANDHEAVY E;CAVATING.

CRAWLER LOAERS



• THE INTRODUCTION OF HYDRAULIC E;CAVATORSDIMINISHED THE MARKET FOR THE CRAWLER LOADER

BECAUSE IT WAS UNABLE TO MATCH THE E;CAVATOR?SLIFTING POWER AND FLE;IBILITY.•HOWEVER3 CRWLER LOADERS ARE CAPABLE OFMANEUVERING ACROSS THE ENTIRE CONSTRUCTION SITEUNDER ITS OWN POWER3 WHEREAS MOST HTDRULICE;CAVATORS REQUIRE TOWING OR TRANSPORT. WHILECRAWLER TRACTORS ARE STILL BEING MANUFACTURED TODAY FOR NICHE MARKETS3 THEY REACHED THEIR PEAKOF POPULARITY IN THE @# .

CRAWLER LOAERS



• A POWER SHOVEL < ALSO STRIPPING SHOVEL OR FRONTSHOVEL OR ELECTRIC MINING SHOVEL = IS A BUCKET6EQUIPPED MACHINE3 USUALLY ELECTRICALLY POWERED3USED FOR DIGGING AND LOADING EARTH OR FRAGMENTEDROCK AND FOR MINERAL E;TRACTION.• POWER SHOVELS AREUSED PRINCIPALLY FOR

E;CAVATION ANDREMOVAL OFOVERBURDEN INOPEN6CUT MININGOPERATIONS3 THOUGH ITMAY INCLUDE LOADING

OF MINERALS3 SUCH ASCOAL. THEY ARE THEMODERN EQUIVALENTOF STEAM SHOVELS3AND OPERATE IN ASIMILAR FASHION.

WHEELE LOAING SHOVELS



•A SHOVEL?S WORK CYCLE3 OR DIGGING CYCLE3 CONSISTS

OF FOUR PHASES:

•DIGGING•SWINGING•DUMPING•RETURNING
