If the design of the building does not make it impossible for narrow-aisle forklifts and pedestrians to be located in the work aisle simultaneously, mobile personal safety systems (Cat. 3) are used to prevent collisions. The system’s laser scanners are integrated into the vehicle and are optimally protected by the cab and the thick doors of the motor compartment.
Floor solenoid switches or RFID transponders report the vehicle’s position as it travels through the aisle and automatically provide:
sideshift limitation in mixed lengthways and sideways storage
Which of the two localisation technologies is most beneficial depends on the number of zones.
The Speed Control Unit makes it possible to take into consideration the specific floor topology and the load condition when programming the speed profiles for diagonal travel. Various high cut-offs can also be programmed as desired.
The lifting height preselection reduces work for the driver when the shelf is being approached by automatically controlling the main and auxiliary lift. When the forklift truck is commissioned, a teach-in procedure is performed to store all of the warehouse’s target lifting heights in the system. In day-to-day operation, the levels can then be selected via quick selection and automatically moved to. Different lifting heights are implemented depending on the load status, so manual fine positioning is entirely eliminated. The lifting height preselection allows the error rate in warehouses with paper-based order picking to be significantly reduced.
The automatic stacking system automates the recurring cycle of stacking and retrieving a load from the shelf. The system automatically differentiates between the stacking and retrieval processes. Regardless of the lifting height when the automatic system is triggered, the system reliably places the load on the shelf or takes it from the shelf. As an option, the position of the load on the fork can also be monitored. The storage cycle is made considerably faster and the driver is spared monotonous activities.
The position assistance system enables precise navigation in the narrow-aisle warehouse. Any storage or retrieval orders are performed semi-automatically by means of optimum travel profiles. For the fine positioning at the target point, the driver can dynamically choose between an automatic or a manual procedure, depending on whether the driver aims to reach the target precisely or would prefer to save a few seconds on the last few metres. Thus with little implementation effort, performance can be increased by up to 30%.
