To assist with maximizing machine life, Caterpillar provides a number of sustainable options such as our Reman and Certified Rebuild programs. In these programs, reused or remanufactured components can deliver cost savings of 40 to 70 percent, which lowers operating cost while benefiting the environment.
Caterpillar offers retrofit packages to bring new features to older machines, maximizing your resource. And, when you go through the Cat Certified Rebuild program, these retrofit kits are part of the rebuild process.
System Match Efficiency
Efficient loading/hauling system starts with a perfect match.
The standard 994H is sized to load the 136 tonnes (150 ton) 785 in four passes. The 994H High Lift and the Extended High Lift load the 177 tonnes (195 ton) 789 in six passes and the 227 tonnes (240 ton) 793 in seven passes. The 994H Super High Lift loads the 177 tonnes (195 ton) 789 coal body in six passes and the 227 tonnes (240 ton) 793 coal body in seven passes.
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.
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.
Narrow Bucket. The narrower 5650 mm (222 in) buckets are optimally matched to load the Cat 785; they are also sized for the 789.
Wide Bucket. The wider 6220 mm (244 in) buckets are optimally matched to load the larger Cat 789; they are also sized for the 793.
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.
Applications: 36 m3 (47 yd3) for coal or other light density non abrasive materials.
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.
