Different types of self-storage units in NYC

Business News | 8 May, 2021 |

Modern storage methods rely on stock units (for example, pallets or boxes made of steel wire) and shelving systems of various types. Some storage systems can be used with automatic conveyor systems to transport particularly large or heavy storage units. Coupled conveyor systems allow a high degree of automation to be achieved in the entry and exit areas of goods.

Bulk storage on the ground

Bulk storage is the term used to refer to storage based on crates, boxes, or pallets stacked directly, without shelving or other devices, on top of or next to each other. It is, therefore, floor storage, that is to say, that the storage units are placed on the floor. The system consists of several parallel loading and picking lanes of uniform width and length. In these corridors, employees move using a conveyor (e.g. forklift, hand pallet truck) to store and pick up goods. In parallel, on either side of the loading and picking lanes are several delivery columns. This is one or more drop-off locations, one behind the other, marked out on the ground. These drop locations have a uniform width, depth, and height, defined according to the load ‘units’ stacking capacity.

On the front end, these deposits’ faces are a front lane extending orthogonally to the loading and picking lanes. The loading and removal corridors are closed at the rear end face; that is to say that one enters and exits only through the front end face. Thus, the front lane connects the loading and picking lanes and the base station, located in the middle of the front end face and consisting of a buffer zone for the supply of goods picked up for the downstream area. A path allows circulation between the point of provision of an upstream zone and the storage and withdrawal system entrance. Likewise, the system has

Goods on stackable pallets, drinks, barrels or tires are very suitable for this type of storage. Block stacking is relatively inexpensive as it does not involve any additional cost for pallet racks. Bulk storage, therefore, falls under the category of static storage systems.

Dynamic shelving

Dynamic shelving can be applied to pallets or bulk goods: dynamic pallet shelving (RDP) or dynamic parcel racking (RDC). The layout of the technical plan consists of a single rectangular storage and collection area. This area is divided into parallel loading lanes, staging areas, conveying areas and picking lanes, all of which have uniform widths and lengths. The conveying zones, which extend to the left and the right along the sampling lanes, are used for the possible construction of a continuous transport means, such as, for example, a belt conveyor. In the delivery areas, the type of self storage NYC in racks is carried out using dynamic racks. Dynamic shelving is made up of multiple shelving columns, which in turn are made up of stacked aisles of similar width, height, and depth. The goods are transported on rollers that cross the corridors independently of an inclination oscillating between three and eight degrees and the effect of gravity. A corridor consists of several storage locations, arranged one behind the other. Dynamic shelving makes it possible to create very compact storage systems on a small storage area.

What is practical is that the different logistical processes, such as storage and shipping, occur in different places. Dynamic racks are loaded on one side, and goods are picked up on the other side. Due to the rollers’ inclination, the stored goods (pallets or cartons) are automatically transported from the loading side to the side of the sample. Dynamic shelving guarantees the application of the “First In First Out” principle as well as optimal monitoring of the batches.

Storage in single-depth racks

The smallest unit in the single-depth rack storage system is a provisioning slot, a shelf. On this basis, several superimposed shelves form a column of shelves, and several columns of shelves arranged one beside the other constitute a shelving unit. Besides, the system has parallel racks of identical design, located on either side along the loading and picking lanes. Hallways are generally uniform in length and width.

The pallet racking Conventional used by self-storage is mainly used for storage racks single depth. Thanks to these types of shelving for unit loads, each pallet is easily accessible. As needs change, these racks can be converted into order picking systems or leveled up in a few simple steps. Single-depth rack storage is one of the most flexible solutions with low investment costs. For bulk goods, a single-depth shelving system consists of shelf racks without screws or bolts.

Storage in double-depth racks

When drawing up the warehouse plan, double rack storage is the same as a picking and picking system for single depth rack storage. Only the racks have two storage locations per shelf, arranged one behind the other. This storage system makes it possible, for example, to store two pallets containing the same type of goods, one behind the other. It is thus possible to store four pallets between the shelving aisles. The volume is thus optimally exploited thanks to the economy of a shelving aisle.

Carousel storage

A carousel storage system consists of an automatic carousel and a semi-automatic picking side. Carousel shelving is built on drop locations or shelves of uniform length, width and depth. Arranged one above the other, they form a cohesive unit called a column of shelving. They are suspended from wheels in a rail system. Additional wheels are often installed, guided by a floor rail: they support the floor shelving columns. A carousel comprises several columns of shelving suspended, one next to the other, which move according to the principle of a circular conveyor a single command. In the storage and order picking area, several parallel and identical racks are placed next to each other, without considering the passage areas between the racks.

Conclusion: At the front of a carousel, racking is the lifting system that can accommodate two load units simultaneously and thus form the interface between the rack and a continuous conveyor. This conveyor allows the upstream zone to communicate with the carousel storage system and the shelving system with the picking locations. In connection to the lifting scheme, buffer zones are provided at the front of the shelves.
