Excavator shears are strong cutting jaws that attach to an excavator’s boom and replace the bucket. They can cut through concrete, steel rods, and pipes. They are useful for demolition and scrap processing, and are quieter than jackhammers when removing sidewalks. They require no additional hydraulic controls and come in different sizes. Some models rotate 360 degrees, allowing for more precise cutting.
One of the many optional accessories for the excavator are the excavator shears. These shears are actually very strong cutting jaws that mount to the boom and attach in place of the bucket on an excavator. Excavator shears are capable of cutting pipes, steel rods and concrete. Acting much like a pair of super-duty shears, excavator shears can cut through rebar (rebar), tires and other materials often found on a construction site. Primarily used for clearing and demolition, shears are also prime candidates for scrap processing and demolition of concrete sidewalks.
Many construction sites are located within residential areas and noise is a specific problem when demolishing buildings and other structural components. Using excavator shears instead of jackhammer attachments is often a welcome option when removing sidewalks and other structural components. Excavator shears allow the excavator operator to simply grip and cut sections of concrete sidewalk instead of hammering them in with a jackhammer. This usually makes the job much more attractive to residents who live near the project. The shears can also be used to cut through any rebar that is within the concrete.
Mounted on the same hydraulic system used by the excavator bucket, excavator shears require no additional hydraulic cylinders or controls to operate. Excavator shears mount to the excavator stick using the same pins that the bucket uses, and are operated using the same controls as the bucket. This allows the excavator operator to open the jaws, grip the object to be cut, and forcefully close the jaws to complete the cutting action. The shears come in different sizes, which correlate to the size of excavator the attachment is intended for. Often a skilled operator can pick up sections of pipe with shears and move or stack them in an orderly fashion.
Some of the best excavator shears rotate in a 360-degree circle, allowing the shears to pull and cut pipes and rebar that may be exposed and coming from any number of directions. Pivoting or rotary excavator shears add another dimension to the excavator’s capabilities in a demolition role. Rotary shears allow the excavator operator to reach high into a steel structure and precisely cut steel spans, removing independent pieces of steel rod in a specific order before toppling the structure completely.
