Demolition Efficiency: Choosing the Right Excavator Attachments

High reach excavators

Successful and efficient completion of a demolition project is similar to any job in that you need the right tools. Those unfamiliar with the demolition industry may think demolition relies on brute force tools like a wrecking ball or explosives, but today's demolition projects require more finesse and precision. These projects allow for more safety, and more salvaging of recyclable and re-usable materials. Excavators are present on almost any demolition site, and the attachments available allow demolition contractors to do the job correctly.

Commonly used attachments

Shears, pulverizers, and universal processors are among the most commonly used excavator attachments in demolition. Shears are just what they sound like. They feature cutting blades that are typically used to cut through steel. Pulverizers look similar to a pair of jaws with sharp teeth used to crush concrete, which allows it to be broken down into smaller pieces and separated from other materials like rebar. Universal processors are like a combination of the other two tools. They can be fit with a variety of jaw sets and used similarly to shears and pulverizers. They are also called multi-functional pulverizers. While they're the most dynamic attachment, universal processors will underperform shears or pulverizers that are specifically designed to handle one type of material. For example, while a universal processor can crush concrete, it won't do the job as well as a pulverizer.

Hydraulic and fixed

In addition to different attachment tools, there are also rotating hydraulic attachments, and fixed attachments. A fixed attachment, like a pulverizor, requires lots of open space in the area it's being deployed to allow the operator of the excavator to position it correctly. For this reason, these fixed attachments are often used in secondary demolition when materials have already been removed from the structure. A fixed pulverizor is extremely efficient in crushing concrete on the ground and removing it from rebar. Hydraulic attachments are more often used in primary demolition because of their ability to rotate in tight spaces. These attachments give operators surgeon-like precision in order to make the right cut on just the area they intend. Hydraulic attachments allow for power and precision, while fixed attachments are all about raw production ability.

Additional attachments

When it comes to sorting and sizing, hydraulic hammers, grapples, and bucket thumbs are often used. Hammers specifically are useful for breaking down large concrete slabs, like foundations, in order to make them easier to transport. Grapples and bucket thumbs are simple tools that lack much sophistication or power. But, they're relatively inexpensive and useful in material handling. Trommel buckets are also used to remove debris from dirt. They include rotating screens that sift through the materials inside the bucket and hold any unwanted debris.At Demolition Technologies, we believe in using the right tool, and people, for the job.
