The most practical alternative to ASRS for plastic crates is a lane-based floor storage system that stacks crate columns in sequential rows directly on the warehouse floor. These systems deliver comparable buffering capacity at a fraction of the capital cost, without the structural requirements, software complexity, or maintenance overhead that come with a full automated storage and retrieval system. Nekos specialises in exactly this type of automated intralogistics solution, helping food production, retail, and logistics facilities replace or avoid complex ASRS installations with purpose-built plastic crate handling and storage systems. The sections below compare the two approaches across cost, capacity, industry fit, and operational logic so you can make a confident decision.<\/p>\n
ASRS for plastic crates introduces significant cost and complexity relative to the actual handling challenge. A traditional automated storage and retrieval system is engineered for pallets or small parts bins in high-bay racking, and adapting that infrastructure to manage lightweight, stackable plastic crates typically means overengineering the solution. The capital investment, installation time, and software integration requirements are all scaled to a problem that simpler automation can solve more efficiently.<\/p>\n
The practical drawbacks fall into several categories:<\/p>\n
For facilities where crate handling is the primary storage challenge, a dedicated plastic crate storage system built around simpler mechanics almost always delivers better economics.<\/p>\n
A lane-based crate storage system is a floor-level warehouse solution that organises stacked plastic crate columns in parallel rows, or lanes, across the storage area. Crate stacks enter at one end of a lane and are retrieved from the other, creating a first-in, first-out buffer that matches the flow of production without cranes, racking, or elevated structures.<\/p>\n
The system works by automating the movement of stacks along guided lanes rather than lifting individual crates into racked positions. An infeed conveyor receives stacks from the washing line or receiving area and pushes them into the appropriate lane. When crates are needed at a filling station or dispatch point, stacks are retrieved from the lane exit and fed into the next stage of the process.<\/p>\n
Our LT Storage system is built on exactly this principle. Stacks are placed directly on the warehouse floor in sequential rows, and the system requires as little as 650 mm of headroom above stack height. This makes it compatible with mezzanine levels and low-ceiling production spaces where a conventional ASRS would be impossible to install. Because the mechanical components are straightforward, the system is also easier to extend, reconfigure, and maintain than crane-based alternatives.<\/p>\n
LT Storage consistently delivers higher storage density per square metre at lower capital cost than a comparable ASRS installation for plastic crates. Because stacks sit directly on the floor in tightly packed lanes rather than in racked bays accessed by a crane, the usable footprint of any given floor area is maximised without the overhead of structural steelwork or lifting machinery.<\/p>\n
The cost advantage comes from several sources. Lane-based floor storage eliminates the crane or shuttle mechanism entirely, removes the need for high-bay racking, and reduces the software layer to lane management logic rather than full warehouse execution system integration. Installation is faster, commissioning is simpler, and the ongoing maintenance cost is substantially lower because the moving parts are fewer and more accessible.<\/p>\n
On capacity, the comparison depends on ceiling height. In facilities with very high ceilings, an ASRS can store more crates in the same footprint by stacking to ten metres or more. In the low-to-medium ceiling environments typical of food production plants, a lane-based system matches or exceeds ASRS capacity because it wastes no floor area on crane aisles or racking uprights. For most crate-handling applications, LT Storage is the more cost-effective choice across both the initial investment and the lifetime operating cost.<\/p>\n
The industries that benefit most from an automated storage and retrieval system alternative for crates are food and beverage production, retail distribution, and contract logistics. These sectors share a common challenge: large volumes of reusable plastic crates that must be washed, buffered, and redistributed continuously, often within tight floor areas and under strict hygiene requirements.<\/p>\n
In food production specifically, crates cycle rapidly between filling lines, cold stores, and washing equipment. The buffer between these stages needs to absorb flow variations without creating congestion or shortages. A lane-based system handles this smoothly because it is designed around crate stack flow rather than individual item retrieval.<\/p>\n
Retail distribution centres benefit because they handle high volumes of standardised crates on predictable cycles. The ability to scale a lane-based system by adding lanes rather than replacing the entire installation makes it well suited to operations that grow incrementally.<\/p>\n
Contract logistics providers value the lower capital commitment and the flexibility to reconfigure storage lanes as client requirements change. Unlike a fixed ASRS, a lane-based crate storage system can be adapted without major structural work.<\/p>\n
An automated crate buffer system manages the complete flow of plastic crates from inbound receipt through storage and out to the point of use, with minimal manual intervention at each stage. The process is continuous and self-regulating, using sensors and control logic to match storage intake and output to the speed of upstream and downstream processes.<\/p>\n
The end-to-end sequence works as follows:<\/p>\n
The buffer stage is the critical regulator in this chain. Without it, any mismatch between washing speed and filling demand causes either a backlog or a shortage. A well-sized crate buffer system eliminates both problems by acting as a reservoir that absorbs variation across the entire production cycle.<\/p>\n
A facility should choose ASRS over a lane-based crate storage system when it needs to store and retrieve many different crate types or product SKUs individually, requires very high vertical storage density in a constrained footprint, or must integrate crate storage tightly with a broader automated warehouse management operation that already runs on ASRS infrastructure.<\/p>\n
