Automated counterbalanced stacker for intralogistics
STILL introduces an automated stacker to improve flexible load handling and integration into intralogistics automation systems.

The EXV-CB iGo automated counterbalanced stacker is designed for intralogistics applications requiring cantilever load handling, precise positioning, and integration into automated material flows.
Technological and application context
In intralogistics and industrial automation environments, material flows often involve heterogeneous load carriers and variable transfer station configurations. Conventional automated stackers with support arms can be limited when handling non-standard loads or ground-level pick-up. Counterbalanced designs address these constraints by combining mechanical flexibility with automated operation.
The EXV-CB iGo extends automated handling capabilities to use cases such as horizontal transport, storage and retrieval, and production line supply.
Technical architecture and operation
The system is based on a counterbalanced stacker architecture with cantilever forks. This configuration enables:
- direct handling of loads without support arms,
- compatibility with various pallet types and custom carriers,
- ground-level load pick-up.
A rear-positioned chassis and integrated counterweight provide stability during lifting operations. Performance specifications include a load capacity of 1,400 kg, lifting height up to 3.8 m, and maximum travel speed of 7.2 km/h.
Navigation and safety rely on a multi-layer system combining laser scanners and onboard sensors. This setup supports obstacle detection, path adaptation, and safe operation in mixed human-machine environments.
Software integration is enabled through the VDA 5050 interface, an industry standard for communication between automated guided vehicles and warehouse management systems (WMS). This allows interoperability with heterogeneous fleets and existing digital infrastructure.
Deployment and integration
Deployment is carried out using the iGo easy solution, based on a plug-and-play approach. This reduces commissioning time and simplifies initial configuration.
The modular system design supports scalability from single units to coordinated fleets. Integration into existing workflows does not require major structural modifications due to compatibility with established hardware and software standards.
Use cases and operational impact
Typical applications include:
- automated supply of production lines,
- inter-zone transport within warehouses,
- handling of non-standard load carriers.
Cantilever forks reduce constraints related to pallet formats and expand the scope of automation. Sensor-based navigation and mechanical stability improve repeatability and reduce handling errors.
Integration via VDA 5050 enables coordination with other automated systems, supporting consistent material flow within a digital supply chain framework.
Technical positioning
The introduction of an automated counterbalanced stacker complements existing intralogistics systems by addressing applications not covered by support-arm designs. The approach combines mechanical design, sensor-based navigation, and interoperability standards.
