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

In general, to transport products and goods, various processes such as packaging, storage, collection/loading, transportation, unloading/delivery, and storage are performed. It is impossible to move goods and goods without going through this process no matter which means of transport is used. Comprehensively looking at the whole of this movement is physical 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 because the need to streamline the flow of goods between them has increased.

Logistics warehouse refers to a storage warehouse for temporarily or long-term loading and storage of all items used in daily life, such as various foodstuffs, beverages, clothing, home appliances, miscellaneous goods, and industrial goods, which are generally mass-produced in factories or production areas. Due to the recent rapid development of the logistics industry, these logistics warehouses are designed and constructed so that they can create new businesses such as inventory management, as well as efficient warehousing, from arranging items in storage stock in the logistics warehouse beyond the simple logistics management dimension. .

These warehouses are equipped with mechanized or automated means for loading and unloading cargo, because the rapid warehousing and delivery of cargo is vital. Typically, automated facilities such as stacker cranes, shuttles, and lifts are used.

The stacker crane is a device that moves goods up and down and horizontally moves goods to and from the rack warehouse while traveling between the rack warehouses, and the shuttle is a device that loads and unloads goods from the rack warehouse while the transfer truck runs horizontally at the same height as each stage of the multi-level rack warehouse. The lift is a device that is fixedly installed at the front and rear of the rack warehouse to move the goods up and down so as to mutually transfer the goods and the goods transfer device, such as a shuttle for loading and unloading goods from the rack warehouse.

When it is desired to withdraw to the outside, it is mounted to be movable up and down along the first and second vertical beams 10 and 20 so that the shuttle body 40 can be withdrawn from the horizontal rail 30 to the outside along the driving direction. do. The lift device 50 is configured to include two horizontal frames 100 , a hoist connection member 200 , and first and second vertical guide modules 300a and 300b .

Two horizontal frames 100 are arranged parallel to the horizontal rail 30 so that the shuttle body 40 can be drawn forward from the horizontal rail 30 and supported. In the horizontal frame 100 , a member having the same cross-sectional shape as the horizontal rail 30 may be used so that the upper surface forms the running surface of the shuttle body 40 , and at least the width is the same as that of the running surface of the horizontal rail 30 , or It is preferable to be formed to have a wider running surface. The two horizontal frames 100 are arranged to be positioned on the same horizontal plane, and the same spacing as the spacing of the horizontal rails 30 so that each horizontal frame 100 can be positioned on the same straight line as the horizontal rail 30 arranged to have
