To provide a weight estimating system that can estimate weight of baggage with high accuracy, while enabling a forklift to smoothly perform cargo handling operation.SOLUTION: A weight 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 shaft, provided in the mast, which extends in a width direction of the vehicle body, a finger bar, provided in the shaft, which has a plurality of support parts arranged separately from each other in the width direction, and a fork supported by the plurality of support parts; a first sensor, mounted on the shaft between the support parts in the width direction, which measures distortion occurring in the shaft; and an information processing device that estimates weight of baggage placed on the fork, on the basis of a measured result by the first sensor, using correspondence relation information showing a relation between loads acting on the plurality of support parts from the fork and distortion occurring on the shaft.SELECTED DRAWING: Figure 1

    【課題】フォークリフトの円滑な荷役動作を実現しつつ、高精度に荷物重量を推定することができる。【解決手段】本開示の重量推定システムは、車体と、車体に設けられたマストと、マストに設けられて、車体の幅方向に延びるシャフト、および、シャフトに設けられて、幅方向に互いに離間して配置された複数の支持部を有するフィンガーバーと、複数の支持部に支持されたフォークと、を備えるフォークリフトと、幅方向における支持部同士の間でシャフトに取り付けられて、シャフトに生じるひずみを計測する第1センサと、フォークから複数の支持部に作用する荷重と、シャフトに生じるひずみとの関係を示す対応関係情報を用いて、第1センサの計測結果からフォークに載置された荷物の重量を推定する情報処理装置と、を備えている。【選択図】図1
