The Challenge
Manual inter-floor transfers take time and require repeated handling
- Connect upper infeed to lower outfeed
- Accommodate 620 × 430 × 290 mm totes
- Maintain stable flow through curves
Our Solution
GBU installed a gravity spiral conveyor with ±4 m vertical elevation and ±3.1 m diameter, integrated with warehouse infeed
- Gravity-driven spiral rollers
- Diameter ±3,100 mm; radius ±1,550 mm
- Curve-drift assessment; motorized rollers proposed as an option
The Outcome
A dedicated spiral route improved inter-floor material flow. Up to 4× faster transfer and productivity versus manual handling is a reported claim pending operational validation.
- More efficient inter-floor transfer
- Continuous gravity-driven flow
- Potential improvement of up to 4×*
## Challenge
Manual inter-floor tote transfer slowed warehouse material flow.
## Solution
GBU implemented a gravity spiral conveyor with ±4 m elevation and ±3.1 m diameter for gravity-driven tote movement.
## Outcome
The dedicated route supports continuous flow and reduces repeated handling. Potential improvement of up to 4× versus manual transfer remains subject to measurement.
