Carton and tote handling
Move rigid-base cartons, totes and containers through packing and dispatch areas.
Carton and unit-load flow
Roller Conveyor Systems
Gravity and powered roller conveyor arrangements for conveying, accumulation, transfer and distribution of compatible unit loads.
Overview
What this system does
Roller conveyors support products on a series of rotating rollers. Gravity versions rely on slope and product momentum; powered versions drive rollers directly or through belts, chains or line shafts. Roller pitch, diameter, frame and drive zones must suit the load base and product geometry.
Main applications
Accumulation
Buffer products between processes using controlled or zero-pressure zones where specified.
Pallet and heavy unit loads
Handle compatible palletized loads using appropriately engineered roller sizes, frames and drives.
Transfer and sorting interfaces
Connect conveyor sections with transfer units, stops and diverters designed for the load.
Operating principle
How it works
Roller Conveyor System
Roller conveyors support products on a series of rotating rollers. Gravity versions rely on slope and product momentum; powered versions drive rollers directly or through belts, chains or line shafts. Roller pitch, diameter, frame and drive zones must suit the load base and product geometry.

Available configurations
Possible arrangements
Gravity roller
Non-powered roller bed for compatible products and layouts with suitable slope or manual push.
Powered roller
Motor-driven zones for controlled movement and line integration.
Accumulation conveyor
Buffered zones using control logic selected for product and process requirements.
Curves and transfers
Direction changes and cross transfers designed around load footprint and stability.
Technical design basis
Technical characteristics
These items identify the information used to engineer this equipment. Numerical limits appear only where the referenced catalogue supports them; other values are confirmed for each project.
Roller conveyor images are from ENTRA’s roller-conveyor gallery. Pallet duty, carton duty and accumulation behavior require different design checks; the same roller layout should not be assumed suitable for every load.
| Roller pitch | Selected so the load is supported by sufficient rollers throughout travel. |
|---|---|
| Roller diameter & wall | Selected from load, impact, span, duty and bearing requirements. |
| Load capacity | Calculated for the actual load distribution, roller count, frame span and support arrangement. |
| Drive arrangement | Gravity, chain, belt or motorized roller solution selected for control and duty. |
| Accumulation control | Zone logic and sensor placement defined by product flow and downstream acceptance. |
Engineering considerations
What ENTRA needs to engineer the right solution
A useful proposal starts with operating conditions and interfaces. Final sizing is confirmed by engineering review.
Load base
Minimum and maximum load dimensions, weight, base stiffness, runners, feet and underside condition.
Roller geometry
Roller diameter, pitch, face width, material, bearing type and load distribution.
Drive and zoning
Gravity or powered operation, drive method, zone length, accumulation logic and speed matching.
Layout and safety
Slope, curve radius, transfers, side guides, stops, guarding, access and emergency-stop strategy.
