The invention relates to a lifting fork, a forklift and a cargo transfer system. The lifting fork comprises a fork device for assembly connection with a forklift body, wherein the fork device comprises fork arms and lifting mechanisms, wherein one end of each fork arm is used for driving connection with the forklift body; each lifting mechanism has an extended state and a contracted state; when the lifting mechanisms are in the contracted state, the lifting mechanisms are hidden and stored under the fork arms; and in the transition process of the lifting mechanisms from the contracted state tothe extended state, the lifting mechanisms are used for forming auxiliary support for the fork arms being in the lifting movement. The lifting mechanisms can form the auxiliary support for the fork arms and cargoes on the fork arms to prevent the unstable center of gravity from causing the tipping of the forklift and ensure the reliable and safe operation of the forklift. The lifting mechanisms of the technical solution can effectively replace a traditional balance weight and fixing and a supporting base, ensure that the fork has the simple overall structure, and is flexible, convenient and fast to use, and are conducive to the reduction of the design cost and manufacturing cost.

    本发明涉及一种升降式货叉、叉车及货物转运系统,包括用于与叉车本体组装连接的货叉装置,所述货叉装置包括:叉臂,所述叉臂的一端用于与所述叉车本体驱动连接;及升降机构,所述升降机构具有伸展状态和收缩状态,当所述升降机构处于收缩状态时,所述升降机构隐藏收纳于所述叉臂的下方;当所述升降机构由收缩状态转换进入伸展状态的过程中,用于对抬升移动中的所述叉臂形成辅助支撑。升降机构能够对叉臂及其上方的货物形成辅助支撑,防止重心不稳而致使叉车倾倒,保证叉车可靠、安全作业。并且本方案的升降机构能够有效取代传统的配重和固定支撑底座,保证货叉整体结构简单,使用灵活便捷,利于降低设计制造成本。
