Roller conveyor chain drive
Transport > Supply > Buffering
Due to their efficiency, roller conveyors are very often used in conveyor technology. Pallet transport is typical, provided that the pallets are transported in longitudinal direction. Depending on the dimensions and weight of the goods to be conveyed, the optimum design is constructed. The basic model is the same for all roller conveyors: frame, supports, support rollers, and motor station with gear motor. The carrying rollers are driven by double chain wheels from roller to roller and guarantee an optimal power transmission via chain circuits.
Suitable for:
- Pallets
- Workpiece carrier
- Cardboard boxes
- And much more…
The advantages at a glance
- The entire steel construction is lasered, welded or screwed and powder-coated – high quality as with all ALFOTEC products
- For light and medium-heavy materials to be conveyed, support rollers with internal deep groove ball bearings to DIN 625, for heavy materials to be conveyed with external pedestal or flange bearings
- Energy-efficient three-phase AC gearmotors (IE3/4) from SEW EuroDrive
- Buffer function through idlers with accumulation properties
- Individual design and production exclusively for you and your requirements
- Steel construction with high-quality powder coating
- Variant additions such as wheel flanges, coating of the support rollers for sensitive goods, tread plates, side guides and much more

Ejector and transfer unit
A diverter lifts the material to be conveyed and diverts it in the desired direction, thereby changing the direction of conveyance. The lift is carried out pneumatically by bellows cylinders or electro-mechanically by an eccentric lifter.
The conveying height and the conveying direction remain the same when moving by means of a turntable or carriage.
Depending on the conveying solution, pushers, linear units or gantry systems for shifting the conveyed material are also available.
Additional options
Our conveyors can be equipped with various options:
- Flanges, bolted or welded
- PVC heat shrinkable tube or rubber coatings
- End stops
- Pneumatic stoppers
- Step or guard plates between the support rollers
- Collision protection with or without feed centring
- Load cells
- Centring or lifting units for precise positioning or fixing of the conveyed material
