Drive-in / through systems provide maximum storage capacity using the minimum amount of space. It is excellent for storing large quantities of homogeneous product
Drive In or Double Access Systems consists of continuous lanes of racking with only a single load and retrieval aisle. Loading and unloading is undertaken by means of counter balance or reach trucks that drive down each lane into the racks. Drive In racking operates on the basis first in last out [FILO], therefore it only suits product, which is stored in sufficient volume to require multiple lanes to ensure stock rotation.
When operating Drive-Through racking, access aisle are positioned on either face of the Drive Block. Drive-Through racking offers the advantage that picking and replenishment can take place independently of each other, allowing first in first out [FIFO] principals to be operated.
Facts about Drive-In Drive-Through Pallet Racking Systems
- Limited stock rotation
- Limited order picking: 20-30% selectivity
- Slow picking rate
- Good product protection
- Average floor area utilisation: 60% net pallet area usage of overall warehouse area
- Pallet redundancy can run as high as 30% if a wide range of different products are stored within the system
- This system is suited for manufacturers of products produced in batch, or in warehouse operations where there are limited product types and pallets cannot be safely blocked stacked
- Mechanical handling equipment: Counter balance / Reach truck
