In large storage and sorting centers, linear transfer vehicles are indispensable tools for the handling, sorting and transportation of goods. These vehicles are able to move goods from one area to another quickly and efficiently on a straight track, improving transportation efficiency and optimizing logistics operations.

However, when moving within the work area, the linear transfer vehicle may run the risk of collision with other equipment, people or obstacles. Especially in busy production environments, accidental contact is inevitable. In addition, due to factors such as acceleration, deceleration or turning, the actual position of the linear transfer vehicle during the movement may have a certain deviation from the expected position, which may cause the safety control system to misjudge the position of the vehicle, increasing potential risks.

To address these potential security concerns, Loeb offers innovative area protection solutions.

The core safety concept of the solution is to protect the transport vehicle’s travel area by using two safety laser scanners, while detecting the presence of people and the real-time location of the transport vehicle in the monitored area. During the process, the safety system uses this information to contour mask the moving vehicle, thereby dynamically adjusting the monitored protection area, so that the monitoring area can be fully protected throughout the process and maintain a high level of safety.
