There is a wide range of excavators and earthmoving machines all for different applications. A standard excavator is a dual tracked machine and the tracks are either metal or rubber. The upper section of the excavator or “house” is able to swivel three hundred and sixty degrees independently from the tracks, allowing an excavator to turn completely around while staying in the same spot. This makes excavator an extremely effective earth moving machine.

An excavator has a long arm called the “boom” with a variety of pivot points allowing the excavators boom to expand and contract at different points making it the perfect digging tool. Attached to the boom is usually a bucket but a variety of different attachments are available. Buckets come in many different configurations some small and narrow for trenching other large deep and wide to move earth and for grading. If you are dealing with hard, rocky, or frozen ground you will want to have teeth on the front of the excavator bucket. This will make it easier to dig into hard surfaces and break up rocky ground. Most excavators also have a thumb attached to the bucket making it easy to pick up rocks, brush, and trees. The last component of an excavator is its blade. The blade is a long relatively flat piece of steel that extends across the front of the excavator from track to track. There are also a number of different attachments for excavators such as augers, jackhammers, compacting plates and post drivers.  

Excavators also come in wide range of sizes with mini excavators weighing as little as two thousand pounds while large excavators can exceed one hundred thousand pounds. Smaller excavators have adjustable tracks to gain entrance through narrow access points. There are many jobs perfectly suited to an excavator but the main use of excavators is digging. Excavators can dig anything from a small shallow trench to giant pits for mining operations. Excavators are also excellent for grading and leveling sites using the bucket to scoop material from a high point and moving it to a low point, and the use the excavators blade to flatten out the ground. Because of the long reach of the boom on an excavator this makes it easy to load large trucks with material. No matter what the job is there is an excavator to suit the size and scale of the operation.

A different variation of excavator is a backhoe. A backhoe is and excavator with a boom and bucket on one side and a front end loader on the other. A front end loader is a big bucket pointed forward for scooping up and moving large amounts of material. Backhoes are a very versatile type of excavator because it gives you the option to dig and trench with the boom and then move or load the material without having to switch machines.

A skid steer is one of the most common pieces of machinery and is also very versatile with a variety of possible attachments. The most common configuration is with a front end loader type bucket on the front. This is used to move material in or out of an excavation site. The large bucket is also excellent for for grading and site preparation. Another popular attachment is forks. This enables you to move pallets around like a fork lift. Using a skid steer in tandem with an excavator is a highly effective and productive way to deploy your machinery.
