Excavator thumbs are attachments that improve the efficiency of excavator buckets by allowing them to grab and move objects. They are controlled by levers and can be removed if not needed. They save time and money by eliminating the need to break up larger debris.
Excavator thumbs are a type of additional equipment that is often attached to excavators used on construction sites. Typically, a thumb is attached to the so-called excavator bucket on digging machinery that is part of a tractor. As the name suggests, an excavator thumb helps make the bucket more efficient by allowing the device to not only scoop up dirt and other debris from a construction site, but actually grab objects and move them around without the need to break them into smaller sections along the way. of time. Just as the buckets are controlled via a series of controls located in the tractor cab, the thumb function of the excavator is managed via a series of levers and controls placed strategically within reach of the machine operator, allowing the bucket to operate in a way not unlike that of a mechanical hand.
Excavator thumbs are considered to be one of several types of attachments that fall under the category of excavator extensions. Considered an add-on to the bucket, a thumb moves back and forth in a manner very similar to the range of motion associated with a human thumb. The result is that the bucket can be used to slide under or around a large object, then press that object closer to the bucket by moving the thumb so that the object is pressed against the bucket. As a result, the item can be picked up with ease and transported to another location.
A simple example of how excavator thumbs work is considering the need to clear an area of a large number of fallen trees. Without the use of a thumb mechanism on a bucket excavator, trees would have to be cut or sawn into smaller sections that the bucket could pick up and haul out of the area. With the addition of an inch, the entire main trunk of the tree can be caught between the bucket and the inch and moved as a whole unit from the area. The end result is that by using the excavator’s thumbs, the area can be cleared of larger debris in a fraction of the time it would take to break up debris and haul debris from the area using just the bucket.
The thumbs of the excavator are often removable, allowing the bucket excavator to be adapted for any purpose. If a job doesn’t require the need to grip and move larger pieces, the thumb can be removed with relative ease. At the same time, attaching the thumb is not difficult, making it possible for a crew to work a large excavator rather than incur the cost of having to operate two pieces of heavy machinery for a relatively small construction project.
