Abstract

A shock-detecting apparatus for an industrial vehicle has a shock-detecting sensor that is fixed to the industrial vehicle for detecting a shock and generating an output signal, a shock value computer for computing a shock value based on the output signal which is received sequentially, a judging device for judging whether or not the shock value is greater than a threshold value, a warning generator for generating a warning signal when the judging device judges that the shock value is greater than the threshold value and a threshold value setting device for setting the threshold value. The threshold value setting device includes a display for displaying a peak value in a predetermined period which allows a user to read the peak value, wherein the peak value is determined by the computed shock value during the predetermined period and a threshold value input unit for inputting the threshold value manually.

Claims

1. A shock-detecting apparatus for an industrial vehicle comprising:

a shock-detecting sensor for detecting a shock and generating an output signal, the shock-detecting sensor being fixed to the industrial vehicle;

a shock value computer for computing a shock value based on the output signal which is received sequentially;
