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.

From Barge to Land In A Limited Footprint
From mobile ship loaders to complete terminal systems, Superior’s conveying equipment is built for high-capacity transfer at deep water ports. Each conveyor is engineered for the long reach, steady flow, and reliable performance that bulk handlers demand when loading or unloading vessels of any size.
Portable by design and customizable by function, these systems can roll into position, handle multiple berths, and operate with minimal cleanup or spillage. Proven in ports around the world, Superior’s marine conveying equipment helps terminal operators move more tons per hour while reducing idle time between loads.
Advantages
Reach and Height Control
Telescoping stinger extension and hydraulic undercarriage lift let operators match barge position and river level throughout the load for accurate, continuous placement.
Fewer Barge Moves
Let the conveyor do the work with automated or manual movements to fully load the holds without tugging, re-spotting, or wasting time repositioning the barge.
Simple Setup and Mobility
Self-contained power, hydraulic operation, and over-the-road portability allow fast moves between docks or terminals, cutting downtime and crew requirements.
Continuous, Controlled Loading
Coordinated motion of the internal conveyor and undercarriage keeps material flow steady and prevents surging or spillage, improving consistency and safety along the dock.
Built for the Long Reach
Loading a barge takes more than capacity — it takes control. This video highlights the conveyors that stretch, swing, raise, and lower to move material exactly where it needs to go.
From floating terminals to river ports, these systems bring land-based efficiency to the water.
