Roller conveyor in restricted space with large range of parts

Roller conveyor in restricted space
with large range of parts
Project description

The restricted space situation and the large range of parts were the reason we realised a multi-track, double-decker roller conveyor with accumulation mode and extremely tight roller pitch (from 31 mm). It is based on the KRAUS RBA50 roller conveyor which has been specially adapted. A suitable sub-structure and the required control functions were part of the scope of supply. Our customer has been using it successfully for years for the production of larger gearboxes for tractors and trucks.

Flat pallet supply roller conveyor in tandem design

Flat pallet supply roller conveyor
in tandem design
Project description

A flat pallet supply roller conveyor in tandem design for extra-long manual pallet trucks with 2 Euro pallets was realised for an equipment manufacturer.
The specification was to supply Euro pallets to a roller conveyor by pallet truck. The design height was reduced to 80 mm. The customer integrated the drive in the lift table pit to prevent it projecting above the roller conveyor.
