Lifting heavy soil at a construction site needs an excavator, which features an arm, bucket, free tracks, and a rotating cab. These components lend mobility and digging power that can make any function from breaking holes and padding to digging trenches easy, saving you a lot of time. Excavators are also used in road construction, mining, and demolitions.
What Is an Excavator?
An excavator is a powerful and versatile piece of machinery used for excavating, digging, grading, and lifting. It consists of an upper body, boom arm, dipper stick, bucket, and cab located at the base of the excavator. Hydraulics are used to power the various parts, which move in different directions allowing excavators to work on uneven terrain.
Excavators can be divided into two main types: crawler excavators with tracks or wheeled excavators with rubber tires. No matter the size or type of excavator you require, they can greatly increase efficiency during construction projects such as excavating a new foundation or creating drainage trenches. If you need help completing your next project quickly and efficiently, an excavator would be a great addition to your construction team.
So, if you’re looking for a powerful and efficient excavator to help with your next project, don’t hesitate to look into the types of excavators available. You won’t be disappointed!
How Does an Excavator Work?
All types of excavators work by using hydraulics to power their various parts and allow them to move in different directions. Hydraulic cylinders are used to control the excavator’s boom arm, dipper stick, bucket, and other components. Each of these parts can be manipulated independently, allowing excavators to work on uneven terrain and perform precise movements with great accuracy.
The excavator also has an engine that powers the hydraulic system to operate even when no electricity is available. With their powerful engines and ability for precise movement, excavators are a vital tool for many types of construction projects and can help to complete work that would otherwise require manual labor more quickly. Crawler excavators have tracks that allow them to move across uneven terrain, while wheeled excavators operate on rubber tires. Both types come in small sizes for use in residential areas or larger ones for large-scale construction projects.
Whether you need help excavating a foundation or digging trenches for drainage, an excavator can help make the job much easier and quicker.
Why Is an Excavator Important?
The types of work that excavators do are plenty. As mentioned, an excavator is an essential tool for many types of construction projects. Its powerful engine and precise movements make it perfect for tasks such as excavating a new foundation, digging trenches, grading the land, and lifting heavy objects.
Without an excavator, these tasks would be much more complex and take much longer to complete without the help of manual labor and a pickup truck. Excavators also come in various sizes, so you can find one that suits your needs, whether you’re working on a large-scale project or just need something small enough to work in residential areas. So if you want to speed up your construction projects efficiently, don’t forget about excavators! They are a great addition to any construction team.
One of the most commonly asked questions about digger hire is whether it is different from an excavator. The two are similar, but they vary in lifting capabilities and functionality. Excavators are as massive as 200,000 pounds with a full rotation. The most popular types include:
Crawlers do not rely on wheels to move, as they have endless tracks that help with their mobility. They are used in heavy-duty road constructions and are often referred to as compact machines. These rely on mechanisms for hydraulic power to lift soil and debris. They also have a wheel system that allows scaling hilly landscapes gradually and handling uneven terrain. Crawlers are slow, but they have excellent balance, stability, and flexibility.
This excavator is often larger than a crawler and relies on wheels to move. The machine has a hoisting system joined to the bucket using a coupler. The bucket’s side away from the coupler is joined with a dragline. The dragline connects the cab and the bucket. The hoisting rope is responsible for moving the bucket up and down, and the towline controls the side to side movements. As draglines tend to be heavy, they will be assembled on the work site. The uniqueness of this excavator makes it ideal for use in civil engineering jobs like dreading canals.
Also called vacuum excavators, suctions have a suction pipe that lets air up to offer more than 400 horsepower. Suction excavators will release water jets that loosen the soil first. The tube has sharp-edged teeth that help create the vacuum that will carry debris and dirt at a speed of 200 miles in one hour. This excavator is used in risky underground applications because it can protect elements from damage.
These excavators come with buckets and booms that face the side opposite of the driver. Such orientation makes it possible for attachments to go above the cab as opposed to going around it. Consequently, the excavator can be used in narrow spaces and tricky turns. Skid steers will commonly be used in residential work, digging pools, and site cleaning projects.
Long reach excavators
These machines have long arms and long boom sections to reach far. The design is meant to serve locations that are difficult to reach. Most of these excavators have an arm that is extendable by up to 100 feet. They are best used in demolitions and over water applications.
The design of the excavator will make construction easy. Often, one may change elements like the arms or booms to change the application of the excavator. For instance, one can add arms to provide holding and digging functionalities. No matter what you choose to use, make sure that it’s the appropriate one for the job.
