Types of Gravity Feed Racks
Gravity feed rack refers to an inclined shelf type that is often used in stock and material handling. It is one of the most efficient of all storage systems where an inventory is installed on rollers or sloped shelves, and the first item is picked-up spontaneously (the first in, first out).
The following are common types of gravity-feed racks:
- Roller Racks: These racks have a series of metal or plastic rollers on the inclined track. This allows the products to easily move down the slope through gravity). Roller racks are ideal for heavy or large containers as well as packages.
- Slot-Feed Shelves: This type of gravity rack has open slots or grooves in each shelf. This allows the products to slide along the edge of the shelf. Slot-feed shelves are suitable for small and flat items such as cartons or boxes.
- Roll-Edge Shelves: These shelves are equipped with a slightly raised edge that ensures products do not fall off easily as they roll.
- Tube Racks: These gravity feed racks are fitted with tubular rollers or cylindrical rollers. These are intended for small and irregularly shaped products.
- Angular Racks: These types of racks have a slanted shelf without rollers. This allows the products to slide down due to gravity. Angular gravity racks are ideal for stable items with a flat base.
- Overhead Tracks: These tracks have a series of horizontal rollers or wheels fixed to a suspended track. This type of gravity rack saves floor space. It is ideal for integration with other material handling systems.
- Adjustable Gravity Racks: These shelves are fitted with adjustable components that enable users to vary the angle and height of the shelves. This allows users to customize the rack according to products of different sizes.
