To provide a gravity center position estimating system which can estimate a gravity center position of baggage placed on a fork of a forklift.SOLUTION: A gravity center position estimating system described in the disclosure is provided with: a forklift that is equipped with a vehicle body, a mast provided in the vehicle body, a finger bar provided in the mast, a mounting part supported by the finger bar, a fork having a first part extending from the mounting part to a side lower than the finger bar and a second part extending from a lower end portion in the first part to one side in a longitudinal direction of the vehicle body, and a restricting part that restricts the fork from rotationally moving, by applying reaction force to a predetermined portion of the first part from the other side in the longitudinal direction; a reaction force sensor, mounted on the fork, which can measure magnitude of the reaction force; and an information processing device that estimates a gravity center position of baggage in the longitudinal direction, on the basis of weight of the baggage placed on the fork, a distance from the finger bar to the predetermined portion and a measured result by the reaction force sensor.SELECTED DRAWING: Figure 1

    【課題】フォークリフトのフォークに載置された荷物の重心位置を推定することができる。【解決手段】本開示の重心位置推定システムは、車体と、車体に設けられたマストと、マストに設けられたフィンガーバーと、フィンガーバーに支持された取付部、取付部からフィンガーバーよりも下方側に延びる第1部分、および、第1部分における下方側の端部から車体の前後方向における一方の側に延びる第2部分を有するフォークと、前後方向における他方の側から第1部分の所定箇所に反力を付与することで、フォークの回転移動を規制する規制部と、を備えるフォークリフトと、フォークに取り付けられて、反力の大きさを計測可能な反力センサと、フォークに載置された荷物の重量と、フィンガーバーから所定箇所までの距離と、反力センサの計測結果とに基づき、前後方向における荷物の重心位置を推定する情報処理装置と、を備えている。【選択図】図1
