There are many configurations available for GOH systems. Most people may recognize a basic GOH system from visits to the local dry cleaner. The basic principle of the GOH is an overhead rail combined with a motorized chain drive (some also feature a screw conveyor) with hooks for garments. This system uses vertical spaces, saving valuable floor space for other uses.
These systems, like most conveyor systems, are highly configurable depending on the application. The most basic is one like that used in a small dry cleaner shop. The system transports garments from the dry cleaning area to the service desk for delivery to customers.
More elaborate GOH systems incorporate computer controls along with other features commonly found in conveying systems. These include items such as sorting, sequencing, variable speed controls, easy transferring from storage to ship-to destinations such as delivery trucks, and containers. GOH systems allow companies the ability to present garments ready for display by carefully spacing items so each arrives without the need for further attention. ABCO Systems design complex storage systems that can be incorporated in pick modules up to 4 levels high.
GOH systems tend to fall into three categories:
Multi-function, static storage, and dynamic storage. Static storage is a basic system with storage rails allowing for a straightforward approach to managing stock. Dynamic storage adds in cross-docking capabilities with the garments moving along trolleys. These are frequently used in high volume operations. A multi-function GOH adds in picking and/or sortation capabilities for better visibility and access to products.
