Stacker and mini-load cranes
The powerful “giants”
Stacker and mini-load cranes are used for automated handling of goods in high racks. Determining the running time, costs, and energy consumption – with consideration for resources for later extensions – helps with the optimal design for units. Stacker cranes are aisle-bound, track-guided vehicles equipped with one or two load-handling attachment(s) that handle carriers in a pallet high-bay warehouse, tray warehouse, or small parts warehouse.
Stacker cranes for curved tracks have a custom shape, and can serve multiple rack aisles or an entire warehouse by means of a switch system. In contract to the classic, aisle-bound variant, this shape is significantly more cost-effective, but provides less power.
If exceptionally high storage/retrieval capacity is needed for automated small parts warehouses – e.g., in connection with “goods-to-person” picking stations, as buffer storage, or for providing goods to production, assembly, or dispatch in precise order – shuttle systems are an ideal choice. They can also be integrated as an add-on into stacker cranes in an automated small parts warehouse.
Stacker and mini-load cranes characteristics:
- Height: between approx. 3 m and approx. 45 m
- Switch system: aisle-bound or multi-lane (for curved tracks)
- Load weight: from 1 kg to 11,000 kg
- Speed: up to over 300 m/min
Advantages:
- High throughput
- Economical
- High energy efficiency if energy recovery options are used
- Reliable
Alternative terms:
- „stacker crane“
- „storage and retrieval machine“ (S/R machine)
