WHAT IS AN EXCAVATOR USED FOR?
As heavy-duty construction equipment, excavators are designed to face rugged challenges, including digging, drilling and churning up hard earth and rock. They’re large, stable and durable machines up to any tough construction job. Since most excavators come equipped with tracks, these machines can easily traverse uneven ground, remaining stable with their wide weight distribution.
HOW TO DIG WITH AN EXCAVATOR
What does an excavator do? Primarily, excavators are meant for digging. As earthmovers, they penetrate soil, rock, dirt, clay and other materials, scooping it up with their front bucket attachment and depositing it away from the newly dug hole. Excavators come equipped with a heavy-duty bucket, which is attached to the stick-and-boom operating arm of the machine.
Inside the cab, the operator is able to rotate the machine, lift the boom and articulate the arm to position the bucket over the front idlers appropriately for digging and depositing. Digging over the sprockets puts extra stress on the final drives that propel the tracks and can lead to pre-mature bearing failure. Whether you’re digging a hole for a foundation, a septic field, a ditch or a pool, an excavator is the best machine for the job.
Understanding your excavator controls is crucial to digging holes or trenches with accuracy. When you’re trying to create a level surface and don’t own leveling or grading equipment, you can use your excavator bucket to finish the area.
Knowing how to dig level with an excavator is a valuable trait, and it takes some practice. You’ll want to position your bucket at the uppermost level of the dirt you’re moving and parallel to the grade you want to achieve. Then, you can begin swinging your boom side to side and displacing soil in overlapping passes, gradually getting deeper until you reach your desired grade.
HOW TO BACKFILL WITH AN EXCAVATOR
The flipside of digging is backfilling — the process of reinforcing the ground by packing in holes and smoothing out the surface so it can support a structure. During backfilling, excavator operators use the displaced soil from the dug hole to fill in around the structure or to cover the hole completely. Tightly compacted backfill prevents the ground from shifting underneath the structure.
Backfilling is done when building a foundation or to cover up trenched ground where pipe, cable and irrigation lines were installed. The backfilling technique is done in layers to help further compact the soil and reinforce the stability of the structure. Keep in mind that excavators are designed to pull bucketed material towards the cab, so aggressive side dozing can lead to structural failure over time.
HOW TO CLEAR TREES WITH AN EXCAVATOR
In construction, landscaping and forestry applications, tree felling is a normal part of resource-harvesting, lot clearing and land management. Felled trees leave behind stumps, which need to be unearthed and removed to prepare for construction or to make room for replanting.
Excavators are the most viable equipment for completely and efficiently removing large stumps. With an excavator bucket, an operator can dig around an old stump and unearth it effortlessly. When clearing stumps using an excavator bucket, operators can also try to preserve as much fill as possible in the bucket as they deposit the old stump aside. Attaching an excavator thumb work tool to your bucket will help grip stumps and their roots as you remove them. A durable three over two pin on or pin grabber grapple provides the ultimate stump removal. Operators can remove and manipulate stumps to get excess dirt and stone out prior to tub grinding to lower grinder repair costs significantly.
