The present invention relates to a safety device for a ready-mixed concrete truck. The safety device for a ready-mixed concrete truck comprises a footplate installed on a vehicle body of a ready-mixed concrete truck to climb towards a mixing drum and descend from the mixing drum, and a guardrail arranged on the footplate. The safety device further comprises: a door frame rotatably arranged on the guardrail; an auxiliary footplate arranged on the door frame to be overlapped with the footplate or withdrawn from the footplate to be spread; a plurality of latches rotatably arranged on the auxiliary footplate to be coupled to the footplate to fix the door frame in an opened state or a closed state, respectively; a plurality of locking blocks rotatably arranged on the auxiliary footplate to press one side thereof by coming in contact with each latch to fix the latch while locking the latch on the footplate; a torsion spring arranged on the plurality of latches and the plurality of locking blocks, respectively to provide an elastic force to rotate the latches and the locking blocks corresponding to the latches in opposite directions to prevent the latches from being opened; and a lever rotatably coupled to the door frame and connected to the plurality of locking blocks by a cable to rotate the locking blocks and then unlock the latches.
