Structures

Designed for the toughest conditions.

Robust Structures

Your bottom line is improved by highly durable structures that achieve multiple life cycles and withstand the toughest loading conditions.

• Full box-section rear frame and four-plate loader tower resists shock and torsional loading to maintain hitch and loader linkage pin alignment.
• Robotically welded structures provide deep weld penetration for maximum durability and fatigue strength.
• Castings increase strength by spreading loads and reducing the number of parts.

Lift Arms

Your key to maximum uptime and productivity is our field-proven lift arms.

• Excellent visibility to the bucket edges and work area through a Z-bar design.
• High load stresses are absorbed by the solid steel lift arms.
• Enhance strength in key pin areas through the use of one piece castings.
• Stress relieved lift arms increase durability and lengthen time to repair.

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.

System Match Efficiency

Efficient loading/hauling system starts with a perfect match.

Application Match

The standard 993K is sized to load the 90 tonnes (100 tons) 777 in 3-4 passes. The 993K High Lift loads the 136 tonnes (150 tons) 785 in six passes.

Efficient Combination

For full truck payloads with minimum loading time, an efficient loading/hauling system starts with a perfect match. Cat wheel loaders are matched with Cat mining trucks to maximize volume of material moved at the lowest operating cost per ton.

Bucket Selection

Selection of the right bucket width depends on penetration requirements and the loading target. Bucket sizes are matched to truck bed capacities for optimum loading efficiency and greater productivity.
