Carousels & ASRS Systems Guide

Horizontal Carousel Systems vs. Vertical Carousel Storage Systems

Carousel storage and retrieval machines come in two main systems designs - vertical carousels and horizontal carousels.

Vertical carousel retrieval units are an Automated Storage & Retrieval System (ASRS) that consists of a series of plastic bins mounted on a heavy duty oval track that rotates vertically to deliver order fulfillment. Vertical carousels use a computer system to control where parts or inventory is stored and can deliver parts or inventory to the operator on command. Vertical carousels provide one of the most efficient and productive means of warehouse storage retrieval on the market today.

Horizontal carousel retrieval units rotate around horizontally on a track, where vertical carousel retrieval units rotate vertically. They offer a flexible integrated inventory management systems design that provides a high density storage solution in a distribution center or warehouse environment. Horizontal carousels are composed of a frame with horizontally rotating carriage of bins that are controlled by a computer system. It provides a high density storage and retrieval solution. Items or parts can be retrieved and delivered to the operator.

Vertical Carousels

Vertical Carousels

Vertical carousels take full advantage of overhead space and can save you up to 70% more floor space when compared to conventional static storage. Operator productivity is increased by up to two-thirds by eliminating the old "walk, search, stock, store" method of material handling.

Vertical carousels bring items to the picker via the shortest route possible, and provide a well-lit work area, offering reduced labor worker fatigue and error. Items are kept out of sight and stored within the carousel, adding security and safety. Workers won't have to climb, stretch or bend to retrieve items because vertical carousels deliver items conveniently to the carousel's pick station, providing one of the most efficient and productive means of storage retrieval on the market today.

Not all vertical carousels are open, however. If you've been to a home improvement store recently, you'll know that they have installed carousels to hold carpets, vinyl rolls and other large rolled goods. This type of unit is called a spool or carpet carousel.

Horizontal Carousels

Horizontal Carousels

A horizontal carousel is simply a rotating carriage of bins. Each bin has shelves (usually 4 or 5). Products can be stored directly on shelves themselves or in totes stored on the shelves.

The operator of the carousel simply stands in front of the carousel and has the products come to him for retrieval. Horizontal carousels save a tremendous amount of time and energy when compared to traditional methods of rack or shelving type storage.

Vertical Lift Modules

Vertical Lift Modules

Similar to vertical carousels, Vertical Lift Modules (VLMs) are designed with space savings in mind. Like vertical carousels, these automated system units use vertical space instead of spreading loads out on the warehouse floor and can achieve a total space savings of up to 80%.

VLMs differ from vertical carousels in that they do not have a continuously rotating series of trays, but instead rely on a shuttle that traverses the height of the unit and picks entire shelves from their set locations. It then brings these shelves to the operator at the bottom of the unit where items can be picked or stored at a safe working height.

Unlike vertical carousels, vertical lift modules also allow for loads of different heights to be stored in the same unit. The unit's software knows how much room it has in any particular storage space and, when needed, can reshuffle the shelves to create the right amount of room for almost any item's height. Some VLMs even have two shuttles so a continuous pick or put cycle can be maintained with little or no interruption. These units are also very secure and simple to use.

Carousel Controls

Carousels can be controlled in a variety of different ways, from basic hand or foot controls to more complex computer controlled systems. SJF has developed an innovative carousel controls suite that can be used with ANY brand, make or model of carousel and can be easily and fully integrated into any existing systems you have.
