Racking Systems Mobile racks
System for maximum space utilisation
Do you want to store your goods as space-saving as possible? Take a look at the mobile racks from STILL. This racking system only requires space for a single working aisle for storage and retrieval – the rest of the warehouse can be completely used for storage.
Highlight of mobile racks: The aisles of this system are mounted on carriages that are moved by electric motors. The STILL mobile rack allows space-saving storage of goods, while each storage location can be directly accessed by moving the rack.
As there is only one working aisle, the available storage space can be optimally used. For example, this is a benefit for cold stores and freezers. Compared to other racking systems, much more goods can be stored on a given floor space. The width of the working aisle in a STILL mobile rack can be adapted to the industrial trucks deployed.
The carriages are operated by controls on the rack support, via remote control or automatically via an interface that is connected to a warehouse management master system. Light barriers are installed for pedestrian protection.
Mobile racks – design
Mobile racks consist of the rack itself, a carriage, running and guide rails as well as control and safety equipment. Light barriers are installed for pedestrian protection.
The rack is usually a pallet or cantilever rack. Therefore long materials or different loads on pallets can be stored on the racks. The length of the dynamic racks and the number and heights of levels are individually adapted to your requirements. Then a suitable carriage, which is able to carry the desired loads, is selected. The carriages move on rails.
Mobile racks – components
A mobile rack system requires rails in the floor on which the mobile racks can move. There are guide rails with grooves and smooth rails, the so-called running rails. The upper edge of these running and guide rails is at floor level. Because the floor is not yet cast in newly constructed buildings, it is often possible to install higher crane rails. The high crane rail can be installed inside the top flooring layer. The layer completely encloses the crane rail firmly anchoring it in the floor. In existing warehouses, flat rails can be installed in a cut groove or directly on the existing floor. Direct installations on the existing floor require building a new top flooring layer afterwards.
The carriage is a central component of mobile rack systems. The racks are mounted to the carriage. The carriages are equipped with motors. These motors move the carriages on the rails along the floor.
There are two- or four-wheeled carriages, fitted with either smooth or guiding wheels. The design of the carriages depends on the planned load weights.
End face protection
The end face of the mobile rack is equipped with light barriers. The light barriers are used for entry/access control in operation.
If the light barriers of the end face protection are interrupted by a pedestrian or a truck while the mobile rack is moving, the system is automatically stopped. In addition, the system is equipped with emergency stop buttons.
Mobile racks – important planning parameters
The picture shows the relationship between shelf levels, lift heights, the required trucks and working aisle widths. The truck and the mobile rack are synchronised and planned in accordance with your requirements.
Mobile racks – accessories
- Lighting control: The controls of the mobile rack can be extended by additional relays, for example, to switch on the lighting in the opened aisle.
- Overnight air circulation: The working aisles are equally spaced between all carriages. As the air can circulate better in this position, this function is frequently used in frozen storages to allow optimum cooling of the goods.
- Order picking position: The working aisle is spaced between several carriages. In this case it must be defined, whether the aisles should be equally wide for all carriages or only for certain carriages. Narrow aisles are formed in which employees are able to pick the orders from the lower levels of the systems. Several employees can work with the system at the same time.
- Control: The controls are used to open a working aisle by moving the individual carriages.
- Remote control: The optional remote control allows to save walking distances and time by opening a working aisle from inside a truck.
- Main switch cabinet: Basically, the main switch cabinet is installed close to the racking system. The main switch cabinet holds the main control components of the system. The different control lamps provide information on the status of the rack and display possible error messages.
- Additional control panel: In order to avoid long walking distances in the warehouse, an additional control panel can be mounted on the rack. This is an additional control unit offering all functions usually only provided by the main switch cabinet. They are also used in cold storages or freezers where the main switch cabinet is located in a separate area outside of the cooling area. With the aid of an additional control panel, all functions can be operated from within the cooling area.
- Truck detection: With the option "truck detection", the system recognises whether the truck is accessing or leaving the working aisle via additional light barriers that are located at mast height of a truck. If a truck leaves the working area, the system automatically switches to "vacant", no additional button must be pressed. The system is able to move immediately.
- Carriage cover: The carriages are equipped with covers (chip board/grids) to protect accessible hazardous areas and to prevent accidents. In addition to chip boards, optional placement frames can be used, which increase the load capacities of the chip boards on the lowest carriage level.
- Rear wall mesh grids/security fences: Rear wall mesh grids are used to protect pedestrians. These components are attached to the back side of a rack or to the floor. Mesh grids prevent employees from being injured by pallets falling off the rack. Security fences ensure that the system can only be accessed through the entrances protected by light barriers.
