Dense racking is an important part of intensive storage racking system. It usually refers to the use of specific warehouse racking and storage equipment to improve the availability of warehouse space as much as possible in the case of the same warehouse space, so as to store more cargos. Dense Racking has many different forms which usually can be divided into the following types according to the different usage of Racking:
Verry Narrow Pallet Racking (VNP) is often evolved from beam racking, by using a special three direction stacker forklift, the lanes can be relatively narrow, so there is more space as shelf storage area. Its features include:
1. The forklift aisle width is generally between 1.6m and 2.0m. High space availability, 30%~60% higher than ordinary beam Racking.
2. High flexibility, 100% picking of cargos can be realized.
3. Well versatility, suitable for storage of a variety of cargos.
Radio Shuttle Racking System is a dense storage system which composed of shelf, shuttle and forklift (stacker). Only one or two lanes for forklifts are left in the space, and the rest space can be used to build shuttle Racking. The vertical movement of cargos outside the lane is realized by forklift (stacker), and the shuttle can move along the track in the lane to achieve the horizontal movement of cargos inside the lane. Its features include:
1. All space except for the lanes with inbound and outbound cargos can be used for cargos storage. There is no need to set up other lanes inside the shelf system, and the space availability is higher;
2. Cargos in this storage form can realize FIFO and FILO;
3. The same lane needs to store the same type or batch of cargos, and be suitable for cargo storage with more quantity and less variety;
4. The lane depth is not limited, which can realize large-area application.
