Hold the Line
Belting is the most expensive component of a conveying system. Superior’s Self-Aligning Idlers ensure that your conveyor belts stay on track, minimizing the chance of severe belt damage.
Concave in shape, the idler’s side guide rollers restrain the belt from running up and over the conveyor. In order to lessen the wear on the belt, the side guide rollers are made with high-grade HDPE that reduces the friction between the idler and belt.

Long Runs & Low Maintenance
Stationary transfer conveyors move material where it needs to go: across the yard, through the plant, or over long distances between processing stages. They form the permanent backbone of many operations, handling high tonnage with consistent, predictable performance.
Each conveyor is engineered for its application, whether it’s a short in-plant transfer or a miles-long overland run. Heavy-duty frames, proper guarding, and easy-access maintenance points make them reliable day after day. Once installed, they simply do their job and keep your circuit connected.

Where Gravity Goes to Work
At Geneva Rock’s Point of the Mountain quarry, gravity isn’t just part of the landscape...it’s part of the design. A custom-engineered overland conveyor carries thousands of tons of material down the slope each hour, harnessing that downhill momentum to generate power for the entire site.
What began as a challenge to move material safely and efficiently became an innovation in sustainability. This one-of-a-kind conveyor reduces emissions, cuts equipment use, and pays back its investment with every load.
