Bucket Ground Engaging Tools

Bucket Ground Engaging Tools

Protect your investment.

Selecting the right bucket will determine the productivity of your loader. The process of selection starts with knowing the density of the material you load. From there, you can select the size and appropriate protection strategies that will suit the rated payload targets of your machine. Your Cat dealer can help you configure your bucket or have a custom bucket made to suit your application.

Heavy Duty Rock Bucket

Applications: Face loading tightly compacted pit materials. Moderate-abrasion factors and high-impact loads are suitable for this bucket.

High Abrasion Rock Bucket

Applications: Face loading iron ore. High-abrasion and moderate-impact loads are suitable for this bucket. A smooth floor is also desirable.

Coal Bucket

Applications: For coal or other light density non abrasive materials.

NOTE: Some applications can be very abrasive. Consider that additional bucket protection can affect the performance of the machine through higher horsepower demand, higher fuel consumption and reduced productivity. With this in mind, it is important that you select appropriate protection for your application.

Enhance the productivity of your loader and protect your investment in buckets with our Ground Engaging Tools (GET). Your knowledgeable Cat dealer will work with you to understand your application and needs for the GET that is best for you. For a full list of Cat GET please visit http://www.cat.com/get.
