The term logistics is an abbreviation for physical distribution, and is a generic term for functions or activities that effectively transfer products and goods from producers to consumers. Generally refers to several activities such as packing, unloading, transport, storage and information.

Typically, transporting products and goods goes through several processes such as packaging, storage, collection/loading, transportation, unloading/delivery, and storage. Regardless of which means of transportation, products and goods cannot be moved without going through this process. The overall view of this movement is material distribution (logistics).

In recent years, mass production, mass sales, and mass consumption have become the trend of the times, and the importance of logistics is gradually increasing as the necessity to streamline the flow of goods between them has grown.

In modern companies, commercial distribution activities, that is, not only part of the transaction, but also logistics activities that deliver products to consumers' hands accurately and quickly, have emerged as an important part. In other words, a view has emerged that by pursuing only reduction of production costs along with economic development, it is impossible to win fierce corporate competition, and that distribution costs should be reduced as much as possible.

Currently, as a means of rationalization of logistics, the construction of distribution centers that intensively build delivery centers, truck terminals, and warehouse complexes around large cities, and a unit load system that aims to achieve consistent transportation using containers or pallets. In the meantime, cooperative and integrated transport aimed at improving the efficiency of transport through the organic combination of transport organizations are being promoted, and some are being promoted by the state.

Logistics warehouses are equipped with mechanical or automated cargo loading and unloading means, because rapid cargo warehousing and delivery are vital, and automation facilities such as stacker cranes, shuttles, and lifts are typically used.

The stacker crane is a device that moves goods in and out of the rack warehouse by moving them up and down and horizontally while moving between rack warehouses.The shuttle is a device that transports trucks horizontally at the same height as each stage of the multi-tier rack warehouse, and loads and unloads goods from the rack warehouse. The lift is a device that is fixedly installed at the front and rear of the rack warehouse so as to mutually transfer the goods and the goods transfer device such as a shuttle for receiving and leaving goods from the rack warehouse to move the goods up and down.

Due to the recent development of online shopping, etc., the rapid processing and efficiency of the automatic warehouse system is also becoming more important as the trend of increasing the order form of small quantities of various products. In addition to efficient space arrangement of rack warehouses, stacker cranes, shuttles, and lifts The compact structure is also recognized as an important consideration in design.

In particular, in the case of the lift, it is fixedly installed in front of the rack warehouse, and a compact structure of the lift is more urgently required for efficient space arrangement of the rack warehouse.In this case, the installation space of the lift is relatively small, and maintenance work is required. There is a problem of being difficult and uncomfortable.
