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.

Unload Trucks Fast and Keep Belts Full
The patented RazerTail Truck Unloader lets you dump material straight from belly or end-dump trucks onto your conveyor system without extra handling. It’s built to transfer large volumes quickly while controlling surge and spillage, so your downstream equipment runs steady instead of starting and stopping with every load.
Available in several capacities, the portable RazerTail Truck Unloader sets up fast and stays low for easy truck access. Hydraulics fold the ramps and discharge conveyor for transport, making it as mobile as the rest of your spread. It’s a clean, efficient way to keep material moving and your crew focused on production, not cleanup.
Models
48-Inch Belt
Engineered for standard-capacity production, the 48-inch model efficiently transfers up to 1,000 TPH of material from highway or off-road haul trucks in continuous operation.
72-Inch Belt
Built for high-capacity operations, the 72-inch model handles up to 1,500 TPH of material and typically accommodates haul trucks for continuous, high-volume truck unloading.
Advantages
Hydraulic Ramp Access
Onboard ramps fold from their transport position quickly, allowing drivers back on or over, dump, and go all while eliminating loader touches.
Self-Cleaning Ramps
Hydraulically powered ramps automatically clear spilled material, directing it straight back into the hopper to maintain cleanliness and eliminate manual cleanup. [Patented]
Adjustable Discharge Height
Power-folding discharge sets the drop height to your next conveyor, reducing spillage, dust, and cleanup.
Ground-Level Wrap Drive
All drive components are reachable from the ground, so belt tensioning and maintenance are faster with less downtime risk.
The Fast Lane to Flow
This animation takes you beneath the grating and into the motion of the RazerTail Truck Unloader. You’ll see how its low-profile design lets drivers dump and roll in minutes — no rehandling, no bottlenecks.
The render shows how controlled material flow, adjustable discharge height, and variable-speed belts work together to keep trucks moving and conveyors full. It’s the fastest way to turn waiting time into throughput.
