The life expectancy of a greaseless bushing is one-year of earthmoving operation (about 2,000 hours).” “Their longevity is optimal in most jobsites and are easy to replace. Greaseless composite bushings work excellent and save time on daily maintenance,” says Shane Kroeker, Director of Strategic Initiatives, K-Tec. “K-Tec scrapers have two or less daily grease points, four monthly grease points, and have greaseless bushings to spend time more productively. You will probably have 10 tires on your scraper and only six on your excavator-truck combo, however an excavator’s undercarriage is one of the machine’s highest maintenance and replacement costs. When you run an excavator and a truck, you have two engines instead of one. When it comes to machine maintenance, scrapers cost less. OPERATING COSTSĭominant factors determining operating costs are machine maintenance, fuel and labor. If you need to buy both an excavator and a truck, that is the most expensive initial capital investment, however, they’re also the most versatile machines of the group, so you can use them in more than just earthmoving. A towed scraper needs a powered machine to pull it, such as a tractor.Īn excavator can’t haul the material away, so it must be paired with a truck. Self-propelled scrapers (also called motor scrapers) are expensive, but they don’t require the aid of any other machines. Scraper options include self-propelled and tow-behind scrapers. If you need to purchase the equipment, you will be spending less on a scraper. Several criteria can help you determine which method is best. Which is the best option for earthmoving applications? Excavators are designed for diverse applications including earthmoving. Scrapers, also called pans, are designed specifically for moving large quantities of earth. Complete your earthmoving projects with the right equipment.
