Used Scrapers For Sale
When you think about a scraper, one of the first things that comes to mind is the small scrapers that wood-workers use to plane the material they’re finishing. Larger scrapers work on the same fashion, just on a much, much larger scale overall. Tractor scrapers are able to move large amounts of earth, often times much more than a smaller grader can, and are perfect for large scale roadways or jobs where you are going to need to lay out large foundations of concrete. You can find these pieces of machinery in used condition, if you have a large construction company that requires them, at much cheaper prices than what you would pay for a brand new machine if you went down to the dealership.
Even though the construction industry has settled down over the last few years, the grader and scraper markets have actually grown quite a bit. The larger machines are being produced with newer, and more technologically advanced models coming out every year. There are two main classifications for these types of machinery: pull-type and self-propelled scrapers. Depending on how much earth you are needing to move, and what other types of machines that you have available, one style of scraper is going to be better for you than the other.
Pull-Type Scrapers – Pull-type scrapers work in tandem to each other, being “pulled” behind a tractor or train in the lead. These scrapers generally have a higher capacity than self propelled scrapers because of their design. Their design allows them to carry much more dirt than self-propelled scrapers.
Pull-type scrapers offer a few distinct advantages over self-propelled scrapers. For instance, there is no need for support equipment, such as bulldozers, because each small scraper in the train loads efficiently on its own. They also do not necessarily need to have multiple scrapers in sync to be able to work to their full capacity, even though most operators will use more than one scraper in tandem with each other.
The design of pull-type scrapers helps them move more soil at a much lower cost per yard than self-propelled scrapers. This means that along with getting more work done, when coupled with the lower price tag of each individual pull-type scraper unit, the average operating costs are substantially lower than when you look at self-propelled scrapers.
Because pull-type scrapers are able to handle a much higher capacity, and are cheaper at moving larger amounts of dirt, you are able to get more work done each day and get the job completed much quicker. These types of scrapers also work much better in softer soils which allows you to squeeze more working days out of the year than you could when using a self-propelled scraper during the wet or rainy seasons. Their ability to work under wetter conditions makes them much better suited for soft soil or sandy areas where motorized, or self-propelled scrapers may encounter problems.
Another distinct advantage that pull-type scrapers offer is that you are able to top-load them if you have a dozer around. Self-propelled scrapers may not contain this capability. The flexibility of the pull-type scrapers also means that you can pull single, double, or triple scrapers if the job that you are working on requires more earth moving.
Self-Propelled Scrapers – Self-propelled scrapers excel in areas where you require power efficiency, rimpull and travel speed because they are able to load the material up to 20% faster, when compared yard for yard, than a pull-type loader is able to. They may not have quite the capacity of the pull-type scrapers, but they make up for it in the versatility that they provide.
The design of the self-propelled scraper makes them slightly more expensive than a pull-type scraper, but the entire unit is self contained. This means that you only have to load one machine when you are traveling from job site to job site, rather than loading multiple trailers with different scraper machines. The hydraulics on the self-propelled scrapers also allow each component of the machine to function independently, which means that you can easily dump material and lift the bowl to make sure that it is completely emptied out, while also positioning the entire machine much more easily.
Because of the higher cost of this type of machinery, you are going to want to avoid purchasing a brand new machine in favor of finding a lightly used tractor that may still contain a factory warranty. Whatever machine you purchase you will want to make sure that it contains a detailed list of all of the work that has been completed on it, from major repairs to routine maintenance. If you are purchasing through eBay the seller should have contact details available so that you can easily retrieve all of this information while you are bidding.
