EARTHMOVING TRENDS TO WATCH IN YOUR BUSINESS

A REVIEW IS PRESENTED OF EARTHMOVING TRENDS ON SCRAPER FLEET MAKE-UP, MACHINE SIZE PREFERENCES, SELF-LOADING SCRAPERS, ALL-WHEEL-DRIVE /TWIN-ENGINE/ SCRAPERS, TANDEM BOWL RIGS, CRAWLER-DRAWN PANS, RIPPING, EARTH COMPACTORS, AND A FEW WORDS ABOUT THE ROLE OF THE COMPUTER IN THE EVOLUTION OF EARTHMOVING INTO SOME SEMBLANCE OF A BUSINESS- LIKE BUSINESS. A MACHINE THAT MERITS INCREASED CONSIDERATION IN THE LARGER EARTHMOVING FLEETS IS THE TWO-ENGINE UNIT WITH POWER ON TWO AXLES. THE TWIN SCRAPER HAS ESTABLISHED ITSELF AS A LOW-COST PRODUCER ON A WIDE RANGE OF JOBS. TWO-ENGINE SCRAPERS ARE ALSO BEING CONSIDERED FOR THEIR VALUE IN HELPING TO REDUCE UNBALANCED PUSH-LOADING, AS WITH THE PADDLE SCRAPERS. A NEW IDEA THAT WILL CAUSE SOME REFIGURING IS THAT OF LINKED, PADDLE-TYPE SCRAPERS. THIS RESULTED FROM THE NEED FOR REDUCING PUSH-LOADING COSTS AND PLANNING THE OVERALL FLEET TO MAKE PUSHER SERVICE MORE EFFICIENT. GREATER USE OF THE LARGE RUBBER-TIRE TRACTOR SHOVEL, FRONT-END LOADER, WHEEL-LOADER IS RECOMMENDED. LARGER, SELF-PROPELLED COMPACTORS THAT REALLY DELIVER THE YARDAGE AND KEEP UP WITH BIGGER SCRAPERS ON THE FILL ARE IN CONSTANT USE NOW. THE USE OF THE ELECTRIC COMPUTER TO CLOSE IN ON THE COMPLEXITIES OF EARTH-MOVING EQUIPMENT PRODUCTIVITY AND COST ANALYSIS IS THE MOST RECENT DEVELOPMENT. IT IS EMPHASIZED THAT IT IS IMPORTANT TO HAVE THE BEST EQUIPMENT FOR THE JOBS AT HAND FOR THE MARKET OUTLOOK OF COST REDUCTION.
