Speed and precision with optimal energy efficiency determine productivity in automated miniload warehouses. The rack system, software, associated conveyor system and the core component, the stacker crane, interact perfectly.
Jungheinrich developed the stacker cranes for miniload warehouses in-house using innovative technologies to deliver peak performance in throughput, space utilisation and energy efficiency. This is how we set efficiency in motion in your miniload warehouse.
The stacker crane not only delivers top travel speed and acceleration, it also offers the highest energy efficiency while making optimal use of the warehouse volume. The best-in-class automation solution for space-saving storage of small parts in containers, boxes or trays.
The STC 2B1A is the world’s most powerful Miniload in its class. With a travel speed of more than 6 m/s and maximum acceleration of more than 5.3 m/s², the goods throughput, i.e. the number of storage or retrieval operations per hour, can be increased significantly. This ranks the STC 2B1A among the very best of high-performance equipment.
Using SuperCaps makes it possible to save the energy released during braking and make it usable again. This enables the Miniload to level out the enormous peaks in consumption that occur during acceleration and deceleration. As a result, the feed-in power can be halved. This means significant cost savings in terms of both energy supply and energy consumption.
Due to the structural design of the guide rail, the floor beam is embedded as a carriage in the rail, significantly reducing the upper and lower approach dimensions. The running surface of the main wheels is only about 55 mm above the floor instead of the market standard of 150 to 250 mm.
Another novelty is the space-saving Omega drive integrated in the mast base. Thanks to its narrow, lightweight design, the two-strand drive can be accommodated between the control cabinet and the mast. As a result, the front and rear approach dimensions are also significantly reduced.
The STC 2B1A therefore achieves the lowest approach dimensions in its class. The result: maximised warehouse volume.
The innovative design and the extremely lightweight construction of the mast were achieved using very light aluminium extrusion profiles with cross braces made from cast aluminium. This allows a low total weight of the Miniload and a flexible scalability of the mast. Within the entire Miniload ‘family’ a mast height of 25 metres can be reached.
