Automated Storage and Retrieval System

Automated/Automatic Guided Vehicle

Vehicles equipped with electromagnetic, optical or other systems for guidance and employ various types of collision avoidance systems. AGVs can have reprogramming capabilities for path selection and positioning. An AGV is often referred to as a driverless vehicle because human intervention is not required to direct the AGV in automatic mode of operation.

Automated Storage/Retrieval System

A combination of equipment and controls, which handles, stores and retrieves materials with precision, accuracy and speed under a defined degree of automation. Systems vary from relatively simple, manually controlled order-picking machines operating in small storage structures to computer-controlled storage and retrieval systems, totally integrated into the manufacturing and distribution process.

Automatic Identification Systems

The application of various technologies, such as bar coding, image recognition, voice recognition and RF/MW transponders, for the purpose of data entry to a data processing system. AIS applications are characterized by data capture at the site of an event. Automatic identification systems combine machine-readable coding symbols to be read by strategically deployed code readers for purpose of automatic sorting, data handling in receiving and shipping, monitoring work in process, and verifying components.

Bi-Directional AGV

An AGV which does not have a dedicated front or back and which can automatically operate in the forward or the reverse directions.

Bridge Cranes

When an application requires hoist coverage over a rectangular area, such as a manufacturing bay, a bridge crane is required. With it, a hoist can be positioned at any point within the rectangle, permitting lifting, lowering and transportation throughout the area. A bridge crane rides on runways, which are a parallel pair of beams that are attached to the building columns and permit the horizontal movement of the bridge crane structure. Bridge cranes come in a number of different configurations, such as top running or under running, single girder or double girder. There are relative advantages to each approach, and the proper selection can only be determined once the application and physical constraints are examined.

Buffer Storage

The part of a warehouse in which back-up or reserve stock is stored awaiting transfer into active storage.

Bulk Storage

An area in the warehouse set aside for storage of multiple pallets of a given product. Storage in warehouses of any large quantity of supplies, usually in original containers.

Carousel, Horizontal

Carousels carry a number of storage baskets suspended at the top and bottom by a powered track system. Order picking takes place from the basket which is stopped at an operator station. Carousels are limited in height to approximately 7 to 10 ft., although greater heights can be obtained by installing additional units on mezzanine levels. Typical installations for carousel units have multiple carousels supporting a single operator station so that the operator does not have to wait on one machine to index the desired basket position. Can be manually or computer controlled with an integrated inventory control system.

Carousel, Vertical

Similar principal to Horizontal Carousel, but operates vertically with a gimbaled tray suspended between the traction chains.

Cart Rack

An accumulative storage system that allows you to store up to five pallets deep per level. All of the pallets on each level, except the last, are placed on a set of trollys/carts that are pushed along the rolling rails. These rails are built on a slight incline, lower at the front, so that the pallets at the back move forward when the pallets closest to the aisle are removed.

In a pushback pallet rack storage system, all the pallets placed on a particular level must contain the same SKU and are managed using the Last In First Out (LIFO) system.

Catwalk

Catwalks are multi-level storage systems that are designed to use the vertical space in a warehouse by using catwalk aisles and employee access stairways. The storage and retrieval process is performed by the employees and eliminates the use of heavy equipment such as forklifts and order pickers. Multi-level catwalk systems maximize storage density in your warehouse. Catwalk systems have narrow pick aisles, reduced cross aisles, and less wasted warehouse space. These systems can be made from custom fabricated rack components, or standard shelving components. Catwalk rack storage systems are composed of custom fabricated pallet rack components and provide for the maximum span and capacity. Rack components provide the maximum span and capacity for catwalk storage.

Ceiling Mounts

When a work area must be free from any support structures that may interfere with operations, Ceiling Mounted Bridge Cranes are an excellent solution to keeping floors clear. With an overhead warehouse monorail system, the hoist and trolley run on a single stationary beam. The monorail allows two axes of hook movement: up/down and forward/back along the monorail beam. Because of their inherent speed and efficiency, monorail material handling systems are an effective method of moving and positioning loads to specific locations. They are available in various capacities. Monorails are best used in applications where materials are to be transported from one fixed point to another fixed location, or through a process.

HIPPA

HIPAA is the United States Health Insurance Portability and Accountability Act of 1996. There are two sections to the Act. HIPAA Title I deals with protecting health insurance coverage for people who lose or change jobs. HIPAA Title II includes an administrative simplification section which deals with the standardization of healthcare-related information systems. In the information technology industries, this section is what most people mean when they refer to HIPAA. HIPAA establishes mandatory regulations that require extensive changes to the way that health providers conduct business. HIPAA seeks to establish standardized mechanisms for electronic data interchange (EDI), security, and confidentiality of all healthcare-related data. The Act mandates: standardized formats for all patient health, administrative, and financial data; unique identifiers (ID numbers) for each healthcare entity, including individuals, employers, health plans and health care providers; and security mechanisms to ensure confidentiality and data integrity for any information that identifies an individual.

Hoists

The selection of the proper hoist may be the single most important factor in designing an overhead crane. It is the hoist after all, that does the primary work of lifting the load. The hoist is usually the most vital component of an overhead crane. Hoists are lifting and pulling devices that use some form of line to move or lift a load. A load is attached to a hoist by means of a lifting hook.  Industrial hoists are primarily used for vertical lifting.  

Industrial hoists can be divided into two main categories, powered and manual. Powered hoists include: Electric, Pneumatic, Hydraulic or fossil fuel .

The manual category includes hand cranked, levered or ratcheted hoists that do not use power to function. Hoists can be used to lift virtually any object from a small car engine to a NASA space shuttle component.

Inventory Turnover Ratio

Measures the return obtained from inventory investments and provides an indication of the movement of materials. Usually expressed as the ratio of annual sales to average inventory investment on hand.

Jib Crane

When a hoisting application can not be accommodated by the line coverage of a monorail, but does necessitate the rectangular coverage of a bridge crane, a jib crane is often the best solution. Jib cranes consist of a horizontally mounted beam, not unlike a monorail, but that can swing in a semi-circle or full circle. Jib cranes are sometimes attached to building columns or can be free standing whereby the boom is attached to the column of the jib crane, that is fastened to your floor. Wall traveling jib cranes can travel on their own track under overhead bridge cranes. Wall traveling jibs allow the operation to transport materials on two levels simultaneously and independently. When used as workstation cranes, several stations can use them. Jib Cranes can be mounted to facility floors, columns or walls to accommodate any space constraints. Expand the Jib Crane’s utility further by using it as an auxiliary lifting device under an overhead crane or by attaching hoists or drives.

-Economically move materials within an individual workstation or between work areas

-Provide supplemental lifting coverage with a full 360° of operation

These drawers are capable of being partitioned and compartmentalized to segregate items in the drawer.

Modular Drawer Cabinet

Modular drawer cabinets make efficient use of storage space by providing secured enclosed storage for small or high-value parts. The operator has a clear view of all stored items as the drawers are withdrawn from the cabinet. An added value of modular drawers is that each drawer can be positioned or sub-divided into smaller storage cells. Modular drawer cabinets, used extensively in tool cribs, parts supply rooms, and maintenance areas, provide higher density, improved organization, more security and protection, and a greater utilization of storage space. Such modular drawer cabinets may be wheeled or fixed in place
