|Stacker-cranes are designed for the automated storage and retrieval of unit loads, in high-bay warehouses.
Take loads into and out of the storage area and move them to the manufacturing floor or loading docks.
Ensure that storing and retrieving goods in pallets, mesh boxes and individual carrier systems happens quickly.
For storage and retrieval they carry out three movements: travel along aisles, lifting and load handling.
They travel in aisles equipped with guide rails, electrical supply, data transmission and control systems.
They are supported on a track and ceiling guided at the top by guide rails or channels to ensure accurate vertical alignment.
Stacker cranes can be of single/ double mast design. They are often supported by a system of conveyors and/or AGVs.
Smaller stacker cranes can often be suspended from the ceiling.
The management software coordinates all the activities, location of stored goods and schedules the retrieval.
|They are typically used in applications where:
-There is a very high volume of loads being moved into and out of storage
-Storage density is important because of space constraints
-No value is added in this process (no processing, only storage and transport)
-Accuracy is critical because of potential expensive damages to the load
|An effective automated storage and retrieval system provides several benefits for supply chain management.
– Reduced labor for transporting items into and out of inventory
– Reduced inventory levels
– More accurate tracking of inventory
– Within the storage, items can be placed on trays or hang from bars.
– Facilitates JIT Just-In-Time production by faster organizing of storage of smaller items next to production lines.
– Helps companies cut expenses by minimizing the amount of unnecessary parts and products in storage.
– Improves organization of the contents of a warehouse.
– Increased space savings as it also allows higher storage density, narrower aisles, etc.
– Automation reduces labor costs while lowering workforce requirements and increasing safety.
– Modeling and managing the logical representation of the physical storage facilities (e.g. racking, etc.).
– Popular items, products sold together can be grouped together or placed near delivery area for faster picking, packing and shipping.
– Enables seamless linking to order processing and logistics management in order to pick, pack, and ship product out of the facility.
– Tracking where products are stocked, which suppliers they come from, and the length of time they are stored.
– By analyzing such data, companies can control inventory levels and maximize the use of warehouse space.
– Firms are more prepared for demand-supply fluctuatins during peak, seasonal and lean periods.
– Data on goods storage provided by the controls can be fed into analytic systems to help companies optimize their supply chain.
