STC 2B1A
- Highly dynamic Miniload
- Maximum energy efficiency
- Flexible scalability
- Maximum utilisation of space
- Reduced operating costs
Thanks to its high-performance values, the Miniload STC 2B1A for automated small parts warehouses is designed to maximise efficiency in your warehouse. Integrated energy storage and an innovative design ensure excellent space-saving storage of small parts in containers, trays or boxes.
The Miniload from Jungheinrich offers significant advantages in comparison with conventional Miniloads. The STC 2B1A impresses both with its outstanding driving dynamics as well as with reduced approach dimensions. Thanks to its consistent lightweight construction and the use of energy storage devices (SuperCaps) specially adapted to driving characteristics and load response, the STC also scores highly with maximum energy efficiency and minimum consumption.
As part of the drive configuration, the SuperCaps allow for particularly intelligent and cost-effective energy management: Energy released during braking processes is stored in the unit’s SuperCaps and fed back to the drive system for subsequent acceleration processes. This ensures a marked reduction in connection and feed-in power and leads to significantly reduced operating costs.
The warehouse volume is also considerably increased, as the STC 2B1A offers the lowest approach dimensions in its class thanks to its innovative rail construction and the Omega drive system integrated in the mast base. In addition, the novel, modular mast design allows for flexible scalability of the Miniload.
Features
Highest performance data in its class
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.
Maximum energy efficiency
SuperCaps are energy storage devices integrated in the unit, which store the
energy released during braking processes and very quickly release it again for acceleration
phases. In contrast to the use of braking resistors, the DC link system with SuperCaps can reduce the energy requirement and associated provisioning costs by up to min. 25 %. The connected load can therefore be reduced by up to 50 %.
High scalability
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 hight of 25 metres can be reached.
Maximising warehouse volume
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.
Minimising operating costs
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.
The entire Miniload ‘family’ is based on the same principle. This means that more than 80 % of all components are also used in other Jungheinrich Miniload models. Maintenance and possible repairs can thus be carried out quickly and easily by the Jungheinrich Service. This in turn leads to minimised operating costs and a high availability of the system.
