Stacker cranes are a great asset in the world of logistics because they help automate the operating cycle. They are the backbone of automated warehouses, thanks to which many companies are able to improve performance, speed up the handling of goods and increase their productivity.

Stacker cranes are machines used to automatically store and pick various types of goods such as pallets, boxes, containers, tyres. They are robots and, thanks to control systems integrated into them and warehouse management software, stacker cranes are able to execute all commands given to them.
These machines are programmed to store products automatically at the pre-determined location, guaranteeing error-proof and low-cost work. Stacker crane operated warehouses can be over 150 metres long and up to a maximum of 45 metres high.
What does a stacker crane consist of and how does it move?
Depending on the goods to be handled, there are different types of stacker cranes: stacker cranes for pallets or for larger and heavier goods, and miniloads, for handling lighter and smaller loads.
In addition, they can handle single- or double-deep and multiple-deep warehouses, i.e. with a variable number of containers per side.
Stacker cranes for pallet are designed for the automatic storage and pick of pallets, boxes and other bulky loads. They move along aisles according to the commands of specific software that allows an operator to manage them.
The dimensions of the pallet stacker cranes can reach a height of 45 metres in their self-supporting warehouse version, with load capacities of over 10 tonnes.
The strengths of automatic stacker cranes include:
There are two main types of pallet stacker cranes: single-column and double-column.
Single-column pallet stacker cranes, as the name suggests, consist of a single column and are most suitable for warehouses with lighter loads. In this sense, we can indicate an ideal pallet weight of between 1,000 and 1,500 kg.
In this type of stacker crane, the structure with two vertical columns corresponds to an elevation cradle in the centre, which allows access to all storage levels. As double-column stacker cranes are stronger than single-mast cranes, they are well suited to handling heavy or bulky loads.
The miniload is a machine similar to the stacker crane but with a tendentially lighter structure, designed to handle boxes or plastic crates. The advantages to be found in this type of stacker crane are the same as those already mentioned in those for pallets, simply related to smaller loads and dimensions.
As far as their configuration is concerned, the miniload stacker cranes also come in single-column and double-column variants. The twin-column stacker cranes for containers can be up to 20 metres high, moving up to four containers weighing over 50 kg each at the same time.
LCS Group, operating since in the fields of internal logistics and industrial automation, designs and manufactures automatic warehouses that can also be customised on request. Since the stacker cranes represent the focal point of the system that makes up the automatic warehouse, it is important to be able to count on a wide choice of products that vary according to the load capacity, the size of the goods and the type of height to be reached for storage.
Your storage operation is a high-value asset. You’re constantly under pressure to speed up throughput, reduce manual labor, and make the best use of vertical space. In this fast-paced landscape, a stacker crane system doesn’t just offer automation—it brings strategic advantage. Let’s explore how integrating one into your racking system transforms your entire warehouse efficiency.
A stacker crane system is a type of automated storage and retrieval system (AS/RS) designed to efficiently manage palletized or containerized goods within high-density racking setups. These systems typically consist of:
By incorporating automation into vertical and horizontal movements, stacker cranes enhance throughput while minimizing human error.
You’ll see immediate gains in how you manage and track inventory. With a stacker crane:
Data source: Studies by the Material Handling Institute indicate up to 99.9% inventory accuracy with automated systems.
UNISTAR supply professional and honest service.
Takeaway: You gain real-time inventory visibility, enabling faster decision-making and fewer lost or misplaced items.
Stacker cranes replace repetitive manual lifting tasks, which reduces the physical strain on your team. Here’s how it benefits you:
According to OSHA, automation can reduce warehouse injuries by up to 40%.
Takeaway: Your staff can focus on tasks that require judgment and oversight while the stacker crane handles the heavy lifting.
Your warehouse has more vertical potential than you’re likely using. Stacker crane systems unlock that space:
Takeaway: You significantly increase your storage density without expanding your footprint.
While automation often requires upfront investment, stacker crane systems pay off in measurable ways:
Estimated ROI: Most facilities recoup their investment in 3–5 years through cost savings and productivity boosts.
Takeaway: You’re investing in scalability, reliability, and long-term profitability.
You need more than machinery—you need intelligent systems. Stacker cranes integrate seamlessly with:
Work with professionals who grasp both the engineering and the digital control dimensions to ensure optimal system performance.
Takeaway: Your warehouse becomes smarter, enabling predictive decisions and agility in the face of demand changes.
Before you make the leap, keep these implementation tips in mind:
Pro Tip: Collaborate with solution providers who offer post-installation support and lifecycle maintenance.
You dramatically reduce manual labor and increase inventory speed and accuracy.
Stacker cranes can go up to 40 meters, unlocking vertical storage you’re likely not using right now.
Yes, compact systems are available and can even outperform forklifts in tight layouts.
Absolutely—with a thorough site analysis, most racking systems can be adapted to support automation.
You’re managing more complexity than ever—higher SKU counts, tighter labor markets, and increasing customer expectations. Investing in a stacker crane system now gives you a competitive edge by automating storage and retrieval, optimizing your space, and ensuring operational resilience.
