- Typical capacity
- For this class of equipment, roller conveyors commonly handle individual items weighing from a few kilograms up to several hundred kilograms, depending on roller strength and spacing.
- Power supply
- Gravity roller conveyors do not require external power. Powered versions typically use 3-phase industrial electricity (e.g., 400V, 50Hz in the UK) for motors, or sometimes single-phase for lighter duty units.
- Typical throughput
- Throughput varies significantly with conveyor length, speed, and item size. Powered units can achieve continuous movement, while gravity systems depend on manual intervention or incline.
- Common materials
- Rollers are typically made from steel, galvanised steel, or sometimes plastic for lighter or more sensitive applications. Frames are commonly mild steel or stainless steel.
- Maintenance requirements
- Maintenance for gravity conveyors is minimal, focusing on keeping rollers clean and free-running. Powered units require regular inspection of motors, belts/chains, and bearings.
- Suitable feed sizes
- Roller conveyors are best suited for items with a flat, rigid base that can span at least three rollers. Item width should typically be less than the conveyor width.
