ツプと、上記油圧ポンプから吐出された圧油が供
給される油圧回路内の油圧を検出する圧力ピツク
アツプと、警報器と、上記回転数ピツクアツプで
検出された回転数と上記圧力ピツクアツプで検出
された油圧が入力され、これらの関係が予じめ記
憶されている正常時における回転数と油圧との関
係より所定量だけずれた場合に上記警報器に警報
を発する旨の異常信号を出力するコントローラと
を有することを特徴とする油圧異常警報装置。 A rotation speed pickup that detects the rotation speed of the hydraulic pump, a pressure pickup that detects the oil pressure in the hydraulic circuit to which pressure oil discharged from the hydraulic pump is supplied, an alarm, and the rotation speed detected by the rotation speed pickup. The rotation speed and the oil pressure detected by the above pressure pickup are input, and if the relationship between these deviates by a predetermined amount from the pre-stored normal relationship between the rotation speed and oil pressure, an alarm is sent to the above alarm. A hydraulic abnormality warning device comprising: a controller that outputs an abnormality signal indicating that an abnormality signal is issued.
