Technical Field

[0001] This invention relates to the field of forklift technology, and more particularly to a three-section, double-stroke, multi-finger hook forklift. Background Technology

[0002] Multi-stroke forks are key components in forklifts or warehousing equipment used to adjust the working length of the forks, achieving different operational needs through a multi-stage telescopic structure. They typically consist of fixed forks and 2-3 stages of movable forks, driven hydraulically or electrically, and can extend to 2-6 meters, suitable for handling long goods (such as steel and timber) or double-pallet operations. Compared to traditional forks, their advantages lie in rapid adjustment, efficient adaptability, and the ability to handle diverse scenarios without frequent attachment changes.

[0003] According to Chinese patent CN222744014U, an extremely narrow-width telescopic fork is disclosed. The transmission gear of the telescopic fork meshes with the second toothed rail to drive the moving rail to move, realizing the first stage of the upper fork's movement. The intermediate gear moves accordingly and meshes with the first and third toothed rails to realize the second stage of the upper fork's movement, unfolding the upper fork within a short distance. However, this telescopic fork requires multiple gears and toothed rails to cooperate and connect with each other, making its structure relatively complex, difficult to manage wiring, and difficult to assemble.

[0004] Therefore, it is necessary to develop a three-stage, double-stroke, multi-finger hook forklift to solve the above problems. Utility Model Content
