ABSTRACT:
The present invention relates to a safety securing system for an operation lever through which work equipment does not operate unexpectedly or suddenly. The safety securing system includes a receiver for receiving a detection signal from an engine rpm detector detecting the engine shaft rpm, a control input detector of the operation lever, and a safety lever position detector, respectively; a data processor for deciding whether the engine starts, whether the operation lever is in the neutral position, and whether the safety lever is in operation; and an output for outputting an engine stop signal, an alarm signal, and a driving signal according to the control input of the operation lever.
