Scrapers

On any construction site, you will see a wide variety of heavy equipment, and one of the largest is scrapers. While some machines you see on sites, such as bulldozers and backhoes tell you just what they are designed to do by their appearance, the scraper, with its upfront cab pulling a large wagon, doesn’t give anything away.

Within that large, heavy wagon section of any scraper is a gated front with a blade at the bottom. With the gate open, the blade scrapes up material as the machine moves forward, forcing the excavated material into the wagon itself until it is filled. The gate is then closed, and the scraper can transport that material away to be disposed of. If you imagine a carpenter’s plane as it shaves off wood, that is the best way to describe how a scraper operates.

It is important to remember that there are several other machines that would at first glance seem to do the same job, a bulldozer for instance, but when it comes to scraping a surface nothing is as efficient as the scraper itself. The ability to scrape and remove material in one go with a single machine sets the scraper apart on site, but it betters the alternatives in other ways too.

Tasks

Scrapers are used for several tasks, most commonly for earth removal on construction sites or even in mining operations. Here, the big blade and ability to remove its own waste material make this purpose-designed machine much more effective than other equipment. In addition, unlike all other earth-moving options that require dry conditions, scrapers can easily move wet soil, which can save a huge amount of time for contractors. In fact, the scraper is particularly suited to heavier soils or other tough materials, and its efficiency advantage increases even further in those conditions.  In today’s world, scrapers have another significant advantage, offering up to a 30% reduction in fuel consumption compared to alternatives, again, reducing costs significantly for contractors.

With all those advantages, it is no surprise that scrapers, and scraper operators, are in high demand. With a skilled operator, scrapers can dig, load, haul and dump with just that one machine, whereas in the past, they may have taken as many as three machines. From volume earth moving to surface preparation on site, the scraper has proved itself a machine that can reduce costs and speed up operations. It may look odd, but it does its job perfectly.

They can be one of the larger pieces of heavy machinery on any site, but the tractor-scraper has managed to be one the least appreciated machines in the industry too. Designed to move large quantities of earth, and consists of a tractor and rear truck, which is a hopper that can be moved up and down as required, and features a sharp blade at the front. When lowered, the blade cuts into the earth and shaves off the top, pushing it into the hopper. When full, the hopper can be emptied at a drop-off point, usually through a hydraulic pusher that forces the collected earth out of the back.

While it may not attract as much attention as the huge dump trucks or the more interesting backhoes and so on, the scraper is an important element of any construction site, moving earth for construction work to begin. Scrapers come in many sizes, although even the smallest capacity would be considered a large piece of heavy equipment by anyone’s standards, and there are variations of the design too. Elevating scrapers use a conveyor belt system to transfer scraped earth into the bowl, or hopper, further back, making loading much simpler, and they are very popular on smaller projects.

From the smallest, 10-yard sizes to the huge mining scrapers, operators can find themselves in all kinds of construction projects, from roadworks or commercial construction projects to huge mining sites or even agricultural use, scrapers are found on all kinds of sites and endless different projects.

Until recently, scrapers seemed to be losing their appeal for construction firms, preferring the multi-tasking capabilities of other machines, however, by incorporating clever technology and features that aid accuracy, speed, and ease of use, modern scrapers from the likes of CAT and Terex are seeing a resurgence in their use. The latest scrapers, featuring computer-controlled unloading features and other operator assistance features, provide a more efficient, cost-controlled earthmoving solution that provides real moving power for construction needs.

However, there are limitations to the scraper’s talents, and you are unlikely to see them used on the smallest of sites, simply due to their size, while they also operate at their best when the distance between loading and unloading is kept to manageable distances. A scraper is not the solution for the long-distance movement of material. However, with the aid of modern technology and improved maneuverability, the scraper today provides efficient earthmoving for a variety of construction, including road and building works and even in agriculture.

For heavy machinery operators, modern scrapers are fantastic machines, with computer aids to help load and unload, and damped hydraulics to smooth the ride on even the harshest site, these machines are in demand and used on most major construction works, offering great career prospects.

Construction sites are full of heavy equipment, each with its own set of tools and purposes. A scraper is a good machine to have around for moving dirt, sand, gravel, ice, and other natural and unnatural materials out of the way when you need to clear an area.

When a backhoe or bulldozer won’t do, call in the scraper!

The issue for construction site managers is having someone on the work site who is qualified to operate a scraper. You need at least one person who is dedicated to the scraper and qualified to operate it under any conditions. When you have such a person on your construction crew, you’ll feel a lot more at ease no matter what challenges you may face.

When you take heavy equipment training from a committed company like Associated Training Services, you’ll be fully qualified to operate a scraper and plenty of other heavy equipment.

Of course, there are different types of scrapers. There are self-propelled scrapers, wheel tractor-scrapers, trailed scrapers, and more. The more of these machines you know how to operate, the more secure your job will be on the construction site.

Learn To Operate A Scraper

Why not enroll today in Associated Training Services’ heavy equipment school and learn how to operate a scraper the right way.

Why scrapers are useful heavy equipment to have on a construction site. In many ways, they are more beneficial than bulldozers. A bulldozer has a blade that is useful for pushing dirt or snow for short distances. The problem is, once the blade has pushed its limit, then you’re done. You have to push it to the side and start over. Scrapers don’t have that limitation.

Scrapers have a blade for pushing. On that note, they have something in common with dozers. But where they have the advantage is being able to pick up the load they push and dumping it into a dump truck-like compartment for hauling. Because of this extra capacity, the scraper can push more dirt in a shorter period of time and haul it off to a dumping site. Having one scraper on the construction site eliminates at least two pieces of heavy equipment but more than likely three.

Without a scraper, you’d have to bulldoze the dirt then pick it up with a backhoe and dump it into a dump truck for hauling. You can do all of that with one scraper.

Keep in mind, however, that a scraper does not have a bucket. It has a blade that forces the dirt into the wagon part of the machine. Once the wagon is full, you drive it to the dumping location.

If you want to set yourself apart on the construction site, learn how to operate a scraper. You’ll be a valuable member of the team with a marketable and valuable skill.

Right now, nearly everywhere in the U.S., there are roads being built or repaired. No matter which highway is traveled there is the familiar row of orange barrels leading drivers on a new path or detour. These new projects are often part of the federal government’s stimulus package, but they are also sometimes the result of local government projects that fulfill a more local need. These barrels and work sites are often an unwanted sight for many drivers, but for heavy equipment operators, this is a sign of a steady job market and good paying jobs.

Regardless of who is sponsoring a road project, there are needs that can only be met by a well-trained road crew filled with numerous heavy equipment operators. One of the most important of these heavy equipment jobs on a road crew is the road scraper operator. The road scraper is the machine used to prepare the earth for the actual road. It slices the top layer of ground in a flat, level slice that will give the road grader a better surface to work with. These road scrapers are able to perform this duty without creating the mess that a bulldozer or other piece of equipment would make.

Quality road scraper training is essential in performing this important duty on any road crew. So, an operator that wants to perform this specialty needs to be certain the training school he is planning to attend offers scraper training. The best heavy equipment training programs will offer a road scraper program, and this training will enable the operator to get a good paying job on a road crew more quickly.
