Dual Radius Design - Excavator Digging Buckets

Excavators are powerful machines designed to handle tough digging and earth-moving tasks. However, as with all heavy machinery, their efficiency depends largely on the attachments they use, particularly the excavator bucket. One advanced feature that is revolutionising excavation work is the dual radius excavator bucket shell. This design not only boosts performance but also increases the longevity of the bucket and improves fuel efficiency. At Rhinox, we pride ourselves on creating high-quality buckets, and the dual radius design plays a key role in achieving superior results. Let’s take a closer look at what this design is, how it works, and why we manufacture our buckets with this feature.

What is a Dual Radius Bucket Shell?

A dual radius shell for an excavator bucket is a specially engineered design that increases the heel clearance of your bucket, allowing it to dig with minimal drag and resistance. The dual radius configuration means that your bucket features two distinct radii (outline below in image 1 by the green and red lines) compared to the standard single radius design (outlined below in image 2 by the red line). The dual radii have been carefully calculated to improve the bucket’s interaction with the ground during operation. This prevents the back of the bucket from striking the ground, ensuring smoother and more efficient digging. The reduced drag created by the dual radius shell design means there's also reduced pressure on the substructure and underside of the excavator bucket, meaning your bucket is going to last longer and maintain it's original shape over time. Reduced drag also means the bucket moves more efficiently through the earth, reducing the amount of fuel required by your excavator to dig.

Why Does Rhinox Manufacture Excavator Buckets with a Dual Radius Shell?

At Rhinox, we understand that an excavator’s bucket is more than just an attachment - it’s a critical component that affects the performance of the entire machine. Here’s why we manufacture our buckets with the dual radius design:

1. Improved Digging Efficiency

The dual radius shell minimises the drag that often slows down digging operations. As the bucket moves more freely through the earth, it requires less force to dig, which translates into smoother operation. This improved digging efficiency allows operators to complete their tasks faster, saving valuable time on site.

2. Enhanced Durability

Reduced drag means that there is less pressure on the substructure and underside of the bucket. The design ensures that the bucket experiences less unnecessary wear and tear, resulting in increased durability. This means that our buckets are less likely to deform or lose their original shape, even under tough working conditions. You can rely on Rhinox buckets to last longer, providing a better return on investment.

3. Fuel Savings

One of the most significant benefits of reduced drag is that it results in less effort required from the excavator’s engine. With less resistance during the digging process, the machine uses less fuel, helping reduce operational costs. This is not only better for your bottom line, but it also contributes to a more environmentally friendly operation by lowering fuel consumption.

Purchasing Excavator Buckets from Rhinox

By incorporating two distinct radii into the bucket design, Rhinox has incorporated a solution that reduces drag, enhances digging efficiency and promotes longer-lasting buckets. This design not only helps you get the job done faster but also ensures your equipment operates more efficiently, saving both time and fuel.
