The invention discloses a car safety circuit for a multi-car parallel elevator, the intelligent multi-car parallel elevator comprises at least two main rails, at least two cars and a switching device, the cars switch the main rails to operate through the switching device, the car safety circuit is a dynamic safety circuit, and when the cars operate, the main rails are switched to operate through the switching device. The dynamic safety loop is connected with a plurality of safety nodes of the main track section, and when the lift car runs, the safety nodes connected with the lift car are not fixed. According to the lift car safety circuit for the multi-lift-car parallel lift, all safety circuits can be ensured to be in a conducting state under the condition that a multi-lift-car lift system operates normally, and the lift cars operate safely.
