Used Plant Machinery Excavators

Excavators are the giants of the construction site. They can dig through concrete, transfer building materials, lift objects into the air, and demolish entire structures. It is no wonder, then, that they are a staple for any construction project. When it comes to buying an excavator as an individual or for a business, there are several tips that can help make the process smoother when trying to choose the right machine for your requirements.

In general, the more knowledgeable the buyer, the better their chances are of finding a quality, user-friendly excavator. At the very outset, they should establish their own needs and expectations: this can help them in making many key decisions. Also important is knowledge of the excavator parts, their functions, available options, and product specifications. This way, they can interpret information about different models in a meaningful way, especially if considering a used model. Following these guidelines can help buyers to select an excavator that can get the job properly.

Do Consider Construction Conditions

Buyers should keep the typical construction jobs they want, do, in mind and ask themselves some questions about what they need and expect from an excavator. First, what type of site do they typically work on? Is it a broad landscape, with plenty of space? Or do they normally work in narrow urban areas between buildings? Next, what kinds of jobs does the excavator need to do? More specifically, how far does it need to reach, how deep should it dig, how high should it lift, and how much should it be able to carry? What functions does it need to perform?

Lastly, buyers need to consider other factors, such as weather conditions, and how they will store and transport the excavator. Clarifying these expectations helps inform decisions during the buying process.

Do Be Familiar With Basic Excavator Parts

While a lot of buyers may be seasoned excavator users, others may not have experience operating the equipment. A familiarity with the parts of an excavator helps buyers understand the features of different models when comparing machines. The following chart details the excavator’s basic structural elements.

Once buyers have familiarised themselves with the parts of an excavator, they are ready to move on to other steps in the buying process.

Do Decide on a Construction Excavator Size and Type Before Shopping

Excavators come in many different sizes and dimensions. Narrowing your choices down to a certain size range and excavator type will help you save time when searching for a machine.

1. Mini Excavators

The term ‘mini excavators’ covers the smallest models available. This category includes: micro excavators that weigh as little as 800 kg or less; mini excavators that average around 3,000 kg; and midi versions that are 6 tonnes or above.

Mini excavators are ideal for construction jobs in small spaces and other lighter work. Their compact design lets them manoeuvre in confined areas, and they only leave minimal damage to the landscape.

Zero tail swing excavators ,are particularly suited to tight working spaces. The counterweight, normally found at the rear of the vehicle, is placed so that it does not swing outside the machine’s track widths. This means the cab can rotate 360 degrees the without risk of it hitting anything nearby.

2. Standard Excavators

Standard excavators can range from 10 to 40 tonnes. These are used for more demanding operations, and where spatial constraints and landscape damage are not a concern.

3. Large Excavators

Large excavators, generally only used for highly demanding work, weigh in between 40 to 70 tonnes. Their sheer bulk makes them impractical for anything but heavy industrial applications.

Types of Excavators

There are a few different types of excavators which buyers can choose from. Perhaps the most common are crawler excavators, which feature steel or rubber tracks moved and guided by sprockets and rollers. These provide maximum stability on uneven surfaces. Slightly less common are wheeled excavators, which move on wheels instead of tracks. This gives them more mobility than crawler excavators, especially moving between jobs. Long-reach excavators feature an extra-long boom, allowing them to reach upper levels of buildings. They are often used for demolition, as they can pull structures down in a controlled fashion.

Do Think About Additional Options

Optional features can make a big difference in an excavator’s efficiency, versatility, and comfort. After assessing the specific demands of their particular work, buyers should take the time to consider which additional features might help.

Excavator Attachment Types

In addition to the standard bucket, which is good for average jobs, there are many other kinds of attachment. Having multiple attachments on hand means an excavator can perform a variety of tasks, simply by switching the attachment. Heavy-duty buckets and severe-duty buckets are made tough for lifting rocks. There are also specialised buckets for pavement removal. When grading or digging a slope, tilt buckets can adjust their side-to-side angle for optimal performance. Sorting buckets are used to separate large rocks from finer debris.

Buckets aside, there are also a number of other attachments, including augers for drilling, thumbs for grasping objects, hydraulic hammers, rakes, mulchers, and rippers.

Do Consider Buying a Used Construction Excavator

Excavators are built to last: on average, they can operate between 8,000 and 10,000 hours before any major parts need to be replaced. Buying a used construction excavator , therefore, is a good way to economise while still getting a quality machine. That said, buyers should take certain steps to make sure the used excavator they’re buying is ready to work; if it is not, they should have an idea of the extent and cost of necessary repairs.

If buying online, the shopper should carefully inspect photos, which must be of the equipment for sale rather than stock images. Communication between buyer and seller is crucial: if a seller withholds information or does not answer questions, it is best to walk away.

Don’t Ignore Excavator Specifications

Product specifications give buyers an idea of how powerful an excavator is, and also help them gauge whether it is the machine for their needs. The chart below explains some of the basic specifications.

Specifications help give the buyer a better sense of how an excavator will perform  and some may even be deciding factors when it is time to choose between different models.

Always Consider Reliability and Ease-of-Use

Buyers get the most out of their excavator when it is user-friendly and reliable: ready for long stretches of work, and easy to operate for maximum productivity. If shopping for an excavator in person, buyers should test out the different machines they are considering. If not planning to run the machine themselves, they should bring the person who is going to be using it. If buying online, shoppers should research user reviews for that model and ideally get to know more about the manufacturer. Possible sources of information include trade magazines, online forums, and experienced professionals.

An ergonomic design gives the operator comfort and control, with everything within reach. The seat should be adjustable and getting into and out of the cab should be feel easy. Visibility should be excellent, both for trench work and driving. Another benefit is uncomplicated access to the engine and hydraulic systems to perform basic preventative maintenance. Finally, buyers should research the reliability and power of a particular model, so they have an idea of what to expect.
