Automated box warehouses
- Ideal for high-volume handling of boxes and containers
- The product is delivered directly to the operator (faster picking)
- Take advantage of heights of up to 20 m
- Order fulfilment even at night or at the weekend
Automated box warehouses, known as miniload systems, are robotic AS/RS solutions designed specifically for boxes, containers, or trays. They optimize vertical space and maximize speed in high-turnover operations.
The miniload travels along the aisle on rails, extracting and depositing boxes or containers in rack positions with complete precision and high speed.
An automated box warehouse combines metal racking with miniload stacker cranes that autonomously manage inbound, storage, and retrieval of boxes or containers, bringing the product to the operator without the operator needing to enter the aisles.
At POLYPAL, we manufacture the racking that makes this automation possible, designed with the dimensional tolerances required by each miniload so that it operates with millimetric precision, safety, and maximum performance cycle after cycle. As a strategic partner, we work from the design stage with the integrator to ensure perfect integration between the structure and the automated equipment.
Benefits of automated box warehouses
Automated storage and retrieval system
The miniload is a specialized stacker crane that moves along a central aisle using a mast guided by rails. Its extractor carriage moves vertically and, through a telescopic or gripper system, inserts or removes boxes and containers with complete precision.
Vertical space optimization
Heights up to 20 m are used, maximizing storage capacity in facilities with limited floor space.
Minimal aisles
Working aisles are extremely narrow, significantly increasing storage density.
Higher operating speed
Miniload systems greatly increase productivity compared with manual systems.
Product-to-person principle
Boxes are automatically transported from their location to picking stations, where the operator works without moving, improving speed.
24/7 continuous operation
Systems can operate without interruption, enabling order preparation at night or on weekends without additional staff.

Frequently Asked Questions
What is the difference between a miniload and a pallet stacker crane?
The miniload is specifically designed for light loads such as boxes and containers, while the stacker crane handles pallets.
What type of boxes or containers does the miniload system accept?
The system is adapted to different box or container formats depending on the requirements of each project. Dimensions and maximum unit load weight are defined during the design phase together with the integrator.
What happens if I need to increase storage capacity in the future?
The systems are scalable. Structures are designed from the outset to allow expansions in height or length, adapting to business growth without requiring a full redesign of the installation.
Are POLYPAL racking systems compatible with any miniload stacker crane?
Yes. Our engineering team works directly with the technical specifications of each integrator to ensure the dimensional, load-bearing, and precision compatibility required by the stacker crane.
