Pallet Detection on Forklifts

Worldwide demand for reliable and accurate equipment for material handling and related logistics solutions is increasing. Material handling depends on the precise positioning of heavy loads and the effective control of fast movements. Materials are transported with equipment such as forklift trucks, mobile cranes, and aerial work platforms.

Logistics applications in the material handling industry usually rely on forklifts for reliably transporting heavy loads to their destination. Pepperl+Fuchs ultrasonic sensors monitor specific areas of the forklift to ensure accuracy and reliability.

With ultrasonic sensors, you can determine whether a pallet is on the fork and how far the fork is inserted under the pallet. This information allows precise control and ensures proper transportation of the material.

For the installation of ultrasonic sensors on the fork section of forklifts, we recommend cube designs like Varikont L2. Because forklifts are often used outdoors, a high IP protection degree like IP67 is necessary. The ultrasonic sensor technology is extremely robust and resists extreme conditions. In spite of rain, fog, or storms, materials are safely transported to their destination.

Detecting the pallet ensures that the fork is located far enough below the pallet before the lift is released. Other machine parameters such as machine control ensure the proper travel speed. This speed depends on the situation. Use a slow travel speed when the mast is extended and the fork is carrying a heavy load. Select a slightly faster travel speed when the mast is extended and the fork is not carrying a load.

Controlling the travel speed reduces the risk of accidents, and increases both the safety and effectiveness of the machine. Ultrasonic technology can reliably detect pallets that are empty, broken, coated, wrapped with transparent foil, or made of metal. Materials can safely be carried to their destination.
