Traditional forklifts cannot indicate the specific shelf level height when operating on high-rise racks, which can lead to minor errors causing goods to collide with the racks, and the adjustment process is time-consuming.
The system employs a movable ruler structure, including a forklift carriage, a forklift mast, a fixed ruler, a movable ruler assembly, and a linkage mechanism. The linkage mechanism enables the first ruler section to rise and fall vertically with the forklift carriage, while the second ruler section moves with the retractable inner mast, indicating the height of the lower and upper shelves respectively. This avoids dense markings and achieves precise matching.
This achieves precise matching of the height of the forklift carriage and inner mast, avoiding the readability problem caused by dense scales and improving the accuracy and efficiency of operation.
