A grapple is a specialized attachment used in demolition and construction work that fits onto heavy equipment like excavators. Think of it as a giant mechanical claw that can grab, sort, and move different types of materials. Workers use grapples to handle debris, scrap metal, logs, or other bulky materials that need to be moved or loaded during demolition projects. It's much like a human hand grabbing and moving objects, but on a much larger scale. Some similar tools include buckets, thumbs, or mechanical grabs. These tools help make demolition work more efficient and safer by allowing operators to handle materials from a distance.
