The invention discloses an alarm system capable of avoiding top-impacting for a lifter. The alarm system capable of avoiding top-impacting for the lifter comprises a power supply, a control switch, areflection-type trigger component, and an alarm component. The control switch and the alarm component are in electric connection with the positive pole or the negative pole of the power supply. The control switch is in electric connection with the reflection-type trigger component and the alarm component. The positive pole and the negative pole of the power supply are both in electric connection with the reflection-type trigger component, which enables the reflection-type trigger component to receive a trigger signal, so as to trigger the control switch to be closed and energized. The alarm system capable of avoiding top-impacting for the lifter can send an alarm to warn an operator of the operation of the lifter, so as to prevent a top-impacting accident. The invention also discloses thelifter comprising the alarm system capable of avoiding top-impacting.
