To provide a forklift having a spreader breakage prevention function that is able to prevent spreader breakage, which is difficult to visually prevent in carrying a container.SOLUTION: A forklift F includes a vehicle body 2, a mast 4, a spreader 6 that is raised or lowered along the mast 4, and a control unit. A spreader 6 has: a rail 60; a pair of left and right support posts 62; a predetermined distance detecting unit 64 that detects whether a distance between a front surface of each support post 62 and other object is within a predetermined distance or not; a lock portion 63 that is locked to a container W; and a lock detecting unit that detects whether the lock portion 63 is locked to the container W or not. If it is detected by the predetermined distance detecting unit 64 that the distance between the front surface of each support post 62 and the other object is within a predetermined distance, the control unit stops forward movement of the vehicle body 2; when it is detected by the lock detecting unit that the lock portion 63 is locked to the container W, the control unit allows the forward movement.SELECTED DRAWING: Figure 1
【課題】コンテナ運搬において目視では防止することが難しいスプレッダの破損を防止することができるスプレッダ破損防止機能を備えたフォークリフトを提供する。【解決手段】フォークリフトFは、車体2と、マスト4と、マスト4に沿って昇降させられるスプレッダ6と、制御部と、を備えている。スプレッダ6は、レール60と、左右一対の支柱62と、支柱62の前面と他の物体との距離が所定の距離内であるか否かを検知する所定距離検知部64と、コンテナWに係止される係止部63と、係止部63がコンテナWに係止されたか否かを検知する係止検知部と、を有し、制御部は、所定距離検知部64によって支柱62の前面と他の物体との距離が所定の距離内であると検知されると車体2の前進を停止させ、係止検知部によって係止部63がコンテナWに係止されたと検知されると前記前進の停止を解除する。【選択図】図1
