To provide a cargo handling restriction device capable of easily realizing retraction to a forklift repair yard while encouraging a diver to inspect a forklift.SOLUTION: A cargo handling restriction device is applied to a forklift with an engine and a cargo handling apparatus. The cargo handling restriction device comprises: a vehicle speed sensor for outputting a signal corresponding to the vehicle speed of the forklift; an accelerator sensor for outputting a signal corresponding to an operation amount of an accelerator pedal; and a control device for executing vehicle speed restriction processing which restricts the vehicle speed using at least the vehicle speed calculated based on the signal of the vehicle speed sensor. The control device sets travel processing S4 to control an engine speed based on the signal of the accelerator sensor, and executes cargo handling restriction processing S5 to restrict the operation of the cargo handling device when the vehicle speed restriction processing cannot be executed due to an abnormality related to the vehicle speed restriction processing.SELECTED DRAWING: Figure 4
【課題】運転者にフォークリフトの点検を促しつつ、フォークリフトの修理場までの退避が容易に実現できる荷役制限装置を提供すること。【解決手段】エンジンと荷役装置とを備えたフォークリフトに適用される荷役制限装置であって、フォークリフトの車速に応じた信号を出力する車速センサと、アクセルペダルの操作量に応じた信号を出力するアクセルセンサと、車速センサの信号に基づいて演算された車速を少なくとも用いて車速を制限する車速制限処理を実行する制御装置と、を備える荷役制限装置である。制御装置は、車速制限処理に関わる異常によって車速制限処理が実行できない場合、アクセルセンサの信号に基づいてエンジンの回転数を制御する走行処理S4を設定するとともに、荷役装置の動作を制限する荷役制限処理S5を実行する。【選択図】図4
