Tiltrotators are rapidly becoming an essential addition to any excavator operator’s arsenal. Positioned between the excavator arm and the attachment, they provide game-changing flexibility, allowing for precise earthmoving in confined spaces and restrictive work areas. 


In this article, we answer some of the most common questions operators have about using screening buckets with tiltrotators and how to get the best results from your setup. 


Find the Answer to Your Question:



Can You Use a Screening Bucket with a Tiltrotator?

Yes, absolutely. Gyru-Star screening buckets are one of the only screening buckets on the market compatible with tiltrotators, making them even more versatile. Tiltrotators enhance the flexibility of the attachment, enabling operators to tackle a wider variety of tasks more efficiently, such as backfilling and cable padding.


Gyru-Star screening buckets are designed to be as close to a ‘plug-and-play’ system as possible. They operate using a single hydraulic feed with a return to the tank, meaning no additional accessories or modifications are required to use them with a tiltrotator. Simply attach the bucket, and you’re ready to work.


Does Using a Tiltrotator Affect the Performance of My Screening Bucket?



Gyru-Star screening buckets are specifically engineered to handle the unique hydraulic requirements of tiltrotators, including lower hydraulic flow rates and higher back pressures. They are compatible with all major tiltrotator brands, such as Engcon, Steelwrist, and Rototilt, without any compromise on performance.


While using a tiltrotator, you may notice the poly-star shafts rotating slightly slower due to reduced hydraulic flow. However, this minor reduction in speed is unlikely to have a significant impact on the bucket’s screening performance. You can continue to screen, mix, and blend materials effectively without issue.


Do I Need to Use a Smaller Screening Bucket with My Tiltrotator?

Each Gyru-Star screening bucket is designed for a specific carrier weight range to ensure safe and efficient operation. Even when fully loaded, the bucket is engineered to remain within the excavator's lifting capacity.


However, when combined with a tiltrotator, the total weight of the fully loaded bucket and the tiltrotator could exceed your excavator’s maximum lifting capacity. For this reason, you may want to consider using a slightly smaller screening bucket than usual, depending on your machine's specifications.


It’s also worth remembering that the tiltrotator will increase the length of the dipper, changing the working geometry.


If you're unsure which screening bucket size is right for your carrier, your local Gyru-Star dealer can provide tailored advice to ensure your equipment remains safe and efficient.


Tiltrotators and Gyru-Star screening buckets are a powerful combination, offering unparalleled versatility and productivity for a wide range of applications. Whether you're screening, mixing, or backfilling, this setup ensures precision and efficiency on every jobsite.
