Tips for Choosing an Excavator Demolition Attachment

Tips for Choosing an Excavator Demolition Attachment

Demolition is a necessary step in construction, but also in scrap yards and recycling facilities. While our ancestors handled demolishing projects by hand, today we use heavy equipment such as excavators, back hoes, and skid steers because it’s much more efficient. Though heavy machinery isn’t quite enough for our daily operations, we also require several attachments for various uses, one of those being demolition. Unfortunately, in the past, many companies either didn’t have the right demolition attachments or didn’t know what to look for in a quality attachment––until now. In the following guide, our experts break down several tips for choosing an excavator demolition attachment. Read on if you’d like to learn more.

Not all attachments are created equally, have a variety

Depending on your company and the type of demolition you perform, you might need all of the following attachments or you might only need just one or two. In construction and structural demolition, many companies merely demolish buildings with the standard excavator bucket. While the bucket is fine for that application, it’s not the only useful attachment. Some of the other important demolition attachments include grapples and magnets as well. Grapples are a vital attachment for more than demolition, they’re also common in shipbuilding, railroad maintenance, and construction. Every company should have a grapple because they give the machine operator the option to lift items with a reliable and more secure grip.

Far too many companies forget to have a magnet in their attachment arsenal which is a mistake for three reasons. First, after the demolition project, how do you plan on cleaning up the worksite? Additionally, most industries (some more than others) have ferrous materials to clean up and a magnet will make that process much easier. Moreover, unless your company handles ferrous materials, you could sell the materials to scrap yard and earn a profit that you otherwise would’ve thrown out.

Consider the material you’re working with

Much like our previous point, knowing the material you handle primarily will help guide your purchase towards the appropriate attachments. If you’re a scrap yard or recycling facility for example, you’ll certainly benefit from a scrap magnet for a couple reasons. First and foremost, you need to sort materials with like materials, and a magnet will help you perform that task efficiently. Moreover, your facility may receive a vehicle that’s still intact. The easiest and most efficient way to handle a complete vehicle is with the aid of a magnet.

We recognize that not all of you run recycling facilities and scrap yards, though. For those of you working in construction, for example, you might only need the excavator’s bucket and a grapple. Though, we’d encourage you to invest in a magnet as well, because it’s better to have the attachment as an option rather than wishing you had one.

Know your excavator’s specifications

While many attachments are universal and fit on most excavators, that doesn’t mean it will fit for sure. Every excavator has different specifications, so it’s important that you know your specifications prior to investing in attachments. Probably the most important specification know is the excavator’s weight limit. Some attachments are heavier than others and you must ensure your excavator can handle such an attachment. If your attachment exceeds the weight capacity of your excavator, you’re asking for machine trouble. Some of the troubles you’ll experience is your excavator being unstable and performing poorly. Ultimately, if you’re overloading the machine’s weight capacity, the machine might not operate at all if you’re well above the weight limit. Furthermore, an attachment that exceeds the excavator’s specifications requires more work from the machine, which can lead to long term damage, expensive repairs, and more frequent maintenance.

Don’t forget to consider to your power source

Similar to the excavator’s specifications, you must take the attachment’s power source into consideration. Are you planning for hydraulic attachments? If so, you’ll need to know your excavator’s circuit requirements and hydraulic flow rating. If the attachment doesn’t receive adequate oil, it won’t operate at peak performance. Alternatively, those of you interested in magnets might opt for a permanent or electromagnet because it doesn’t require a hydraulic power source, although you might need a generator or battery. Without the appropriate power source, excavator demolition attachments won’t perform as well as they should, and poor performance leads to inefficiencies. Few metrics are more important in demolition than efficiency and productivity, and an inadequate power source will force your attachments to operate poorly and cost your company time and money.

Don’t skimp on quality

As with any company, you’re probably trying to keep expenses low by searching for the best deal possible, and there’s nothing wrong with that. The problem with looking for the best deal is that people often settle for lower quality, and your excavator attachment is no place for mediocre quality. Whether you work in construction, metal recycling, or scrap yards, you know that your equipment is the lifeline of your business, so why would you want unreliable attachments? Your company and your workers deserve to work with high-quality equipment, so invest in quality and invest in your business’s future.

There are several factors to consider when buying attachments for heavy equipment and we get that. To help you make an educated decision that’ll improve your business, we put together this list of tips for choosing an excavator demolition attachment. We’d argue that the most important point on this list after the safety of your workers, is the quality of your attachments.

You shouldn’t take quality lightly because it directly affects your business’s bottom line, the safety of your workers, and the efficiency of a job site.

Safety Risks Faced by Recycling Workers

Safety Risks Faced by Recycling Workers

When someone considers working in the recycling industry, they usually don’t consider the hazards involved in the career. Additionally, the managers and decision makers at a recycling facility might not be aware of the safety hazards their workers face day in and day out. It’s important that everyone in the recycling industry is fully aware of safety risks, how they can prevent accidents, and how to keep themselves safe. While building awareness sounds simple enough, it’s your responsibility as the facility manager to execute a training plan to ensure everyone is aware of the risks. However, you can’t build a training plan if you don’t know what the risks are to begin with. Our experts put together a guide discussing the safety risks faced by recycling workers for your reference. Read on to learn more.

How Electromagnets Work: The Basics

How Electromagnets Work: The Basics

Today one of the most widely used industrial magnets are electromagnets because of their versatility and power-saving capabilities. Unlike permanent magnets, which have a constant magnetic field, electromagnets are only active when a power source is turned on. In most cases, the power source can vary from a generator to the motor on heavy equipment. Electromagnets changed the magnet industry for the better, but how exactly do electromagnets work? In our guide below, our experts explain how electromagnets work: the basics. Read on to learn more.

An electrical current

The primary factor that sets electromagnets apart from every other magnet is, well, electricity. An electromagnet operates based on an electrical current that surrounds a wire or coil, but not just any wire or coil. A straight wire won’t produce a strong magnetic pull, so the wire typically wraps around another rod (solenoid) made of a ferrous material to enhance the magnetism.

The solenoid and wires directly relate to the magnet’s strength

To have a reliable electromagnet, you need three components: a solenoid—or rod—a conductive wire, and a source of electricity. If you were to take one of these factors away, you wouldn’t have an electrical charge nor an electromagnet. The solenoid and wire determine the strength of the magnetic pull. If the wire is loosely wrapped around the rod, you’ll have a low to medium magnetic pull. On the other hand, you’ll get a stronger magnetic field if you wrap the wire tightly.

By wrapping a conductive wire around a piece of metal and providing electricity via a battery, generator, or motor, you’ll have an electromagnet. Though we’ve highlighted the basics of how electromagnets work here, there’s a lot more science behind their properties and capabilities. We merely spared you the physics involved, such as Ampere’s law and Biot–Savart’s law.

Two-Shaft Shredders vs. Four-Shaft Shredders

Two-Shaft Shredders vs. Four-Shaft Shredders

Industrial shredders are common in several industries, but most notably scrap and recycling yards. While there are several variations of shredders including single shafts, two shafts, and up to four shafts. Each has its own advantages. If you’re searching for more information, our experts discuss the two-shaft shredders vs. four-shaft shredders in a comprehensive guide below.

Two-shaft shredder

The shafts in a shredder essentially determine the materials you can granulate using that shredder. In most scenarios, a single- or two-shaft shredder will be sufficient. Two-shaft shredders have two rotating cutting disks. This type of shredder is often used for applications such as composting and breaking down metal, tires, plastics, and more. An important factor to consider when choosing a shredder is the desired particle size. Two-shaft shredders are not ideal for scenarios where you need a very small, almost fine particle. On the other hand, if you merely need to compress the size of a material, a two-shaft shredder will suffice.

Four-shaft shredder

If you need to compress and completely destroy a material, a four-shaft shredder is best for you. Since there are double the rotating cutters in a four-shaft shredder, you can expect materials to be broken down even further. Four-shaft shredders are common for facilities that need to destroy sensitive information such as electronics and hard drives. In other words, unless you need to granulate materials to small particles or destroy electronics, you probably don’t need a four-shaft shredder.

As we can see when comparing two-shaft shredders and four-shaft shredders, the majority of applications will only need a single- or two-shaft shredder. Every recycling facility should have at least one shredder. You’re going to operate much more efficiently, which will allow you to offer faster turnarounds for customers.

If you’re in need of industrial shredders, granulators, industrial magnets, excavator magnets, motors, or repair services, Moley Magnetics has you covered.
