1. Fast & dependable
Daifuku offers a variety of stacker cranes to fit your specific load profile and weight, building dimensions, and operating environment. All systems feature high-quality drives for fast, smooth, and reliable performance.
2. Advanced control system
Daifuku’s local intelligent network control system offers a comprehensive solution: from front-end controls to full-scale inventory management computer systems. Our software provides full control of stacker cranes and their peripheral load-handling systems. The software monitors the system in real time to assist with trouble and control auxiliary equipment such as quantity indicator displays for order picking.
3. Simple operation & maintenance
End-of-aisle controllers allow operators to easily manage loads without entering stacker crane aisles. The power supply and other major components are readily accessible for quick and easy maintenance.
4. Improved operation efficiency
The high-speed stacker crane automatically stores and retrieves loads quickly and efficiently. Not only does this dramatically reduce cycle time, but it also reduces the number of forklifts and forklift traffic. Daifuku's stacker cranes reduce energy costs by using low electricity and regenerating power.
Standard configuration of AS/RS. One stacker crane with access to two rack rows (one on each side).
One stacker crane with access to four rack rows (two on each side).
Great for high-density storage of low/med throughput.
Multi aisle change
A single stacker crane uses a traverser to change aisles and access multiple rack rows. Additional cranes can be installed later to accommodate throughput growth.
Two stacker cranes operate simultaneously in the same aisle to maximize throughput capacity and resiliency.Dual control technology video
