Excavator and wheel loader buckets can be useful tools for clearing demolition debris, but they can also be costly if the bucket isn't up to the task. The first step is to choose the most appropriate bucket style.

In the demolition industry, the more rugged the better with any attachment. "Severe-duty is the correct spec to apply to attachments," says Dale DeWeese, national sales manager, Werk-Brau. You should also maximize the amount of protection available. "Wear straps and wear plates are always recommended."

Tracy Black, Kenco Corp., agrees, noting, "If a contractor is demolishing concrete, brick, stone or other abrasive materials, then a severe-duty attachment should be used. These are typically constructed of AR-400 or T-1 steel.

"The AR-400 provides great abrasion-resistant qualities, while the T-1 has a high tensile strength, which flexes to deter cracking under stress," Black explains. These steels or equivalent should be used in high wear areas, such as cutting edges, cheek plates, wear straps, etc. However, manufacturing practices, and durability, can vary. "Some buckets may have additional or thicker plating, which extends their service life."

Dealing with stress
Doug Pierce, marketing manager, ESCO Corp., recommends considering both structural strength and abrasion resistance when selecting a bucket for demolition applications. But keep in mind that buckets have limitations in this type of work.
