Description

Technical Field

[0001] This utility model relates to the field of forklift technology, and in particular to a forklift for transporting long workpieces, its fork structure, and drive equipment. Background Technology

[0002] Electric forklifts are commonly used in the transportation of large or heavy items, lifting and delivering them to designated locations via their forks. For example, patent 202223486804.6 discloses an adjustable-width AGV forklift fork structure and AGV forklift, including a mounting base, a load-bearing slide rail, forks, and an electric push rod. This patent uses the electric push rod to move two forks along the load-bearing slide rail, allowing the forks to move closer or further apart, thus adjusting the distance between them to handle goods of different widths. However, for long and slender workpieces, simultaneously handling multiple such workpieces can easily cause them to fall from the fork tips. Furthermore, this patent mounts the slide rail on the base panel, ensuring the distance between the forks does not exceed the base panel's width, making it suitable for shorter goods. When placing long workpieces, careful attention must be paid to maintaining the center of gravity to prevent them from falling. Utility Model Content

[0008] As an optional implementation, the first limiting member is a limiting plate, and the limiting plate is perpendicular to the top surface of the corresponding fork.

[0009] As another optional implementation, the first limiting member further includes a plurality of pads stacked on the limiting plate, the stacking direction of which is along the length direction of the corresponding fork.

This allows for the stable placement of long workpieces of different sizes. The other end of the forks is equipped with a limiting component, which allows for the placement of one or more workpieces without them easily falling off the fork tip.
