With three new versions of the semi-automated N20 C SA order picker, operators can conveniently raise the forks of the Linde order picker to a comfortable working height and no longer need to bend down when setting down goods. This reduces walking distances between the vehicle and the storage location.
“Increasingly digitalized processes and supply chains, a growing number of product variants, and, last but not least, demands for the highest possible pick rates are driving logistics managers in warehouses and distribution centers to seek out automation solutions,” says Manuel Seidel, Product Manager in the Automation division. “Even if the actual picking process—that is, picking the goods from the shelf and placing them on the pallet—is still manual, the N20 C SA can at least assist the operator in moving the device along the aisle. This saves time and energy and increases productivity.”.
The compact N20 CL SA model is designed for order picking from the lowest shelf level onto pallets that can be loaded with up to 1200 kg. The forks can be raised to an ergonomic height, allowing the operator to place the picked goods in a back-friendly posture. Thanks to its compact design, the order picker remains maneuverable even when fully loaded. The N20 CD SA allows two pallets to be picked up separately and stacked on top of each other, making it particularly suitable for longer distances. Heavy goods are stored on the initial lift, while fragile items are placed on the main lift.
Thanks to its long load arms and additionally liftable forks, the N20 C LoL SA can load two pallets with goods in a single picking cycle. The operator starts with one pallet at the desired height, while the second is secured vertically to the back of the forks with a special locking mechanism. Once the first pallet is filled, it is lowered onto the load arms and positioned at the front of the forks. The second pallet is then transferred to the forks and can also be loaded at an ergonomically comfortable height. Operators control the mast from the right or left side of the backrest.

The new mast variants expand the range of applications. Their key feature is the two driving modes, which address the two main customer applications: In the first mode, the operator moves in a U-shape within the racking. They initially pick items only on one side and then switch to the other. The vehicle follows them through the aisle, navigates around minor obstacles, and stops automatically at the end of the aisle. If the operator stops to pick up goods, the vehicle also stops; if the operator continues, the vehicle automatically moves on. This saves operators considerable walking distance, as they don't need to return to the operator platform each time to move the vehicle to the next racking position. The second driving mode is used when picking is performed simultaneously on both sides of the racking. This results in a Z-shaped pattern. In this case, the operators send the vehicle ahead using a remote control. At the end of the aisle, the operator enters the order picker and drives to the next aisle.
When asked for whom the semi-automated option of the order picker would be worthwhile, Manuel Seidel says: “Depending on the application, an efficiency increase of between six and 15 percent can be achieved. Assuming approximately ten percent higher productivity, the additional investment in a two-shift operation, with industry-standard labor costs, will pay for itself in about a year.” Another advantage: According to the manufacturer, the vehicles can be seamlessly integrated into the customer's existing processes.
High-performance safety scanners integrated at the front ensure a high level of safety for the semi-automated vehicles. These scanners detect people, obstacles, and other vehicles, preventing collisions. To provide a safe and comfortable working area for the operator, the vehicle maintains a minimum distance of 50 cm from the racking.
