The invention relates to a guide trolley of a low-rolling-resistance tire cord tearing machine. The guide trolley comprises a deviation rectifying mechanism, a locking mechanism and a guide trolley main body, wherein the lower end of the guide trolley main body is provided with four pulleys by using which the guide trolley main body moves, wherein the pulleys are distributed on the lower end of the guide trolley main body in a rectangular shape; one side of the guide trolley main body is locked by the locking mechanism, and the guide trolley main body can be driven by the deviation rectifying mechanism to move horizontally in a reciprocating mode. The guide trolley has the advantages that an original fixed guide trolley is changed into a movable guide trolley; when nylon cloth is loaded, the locking mechanism is unlocked firstly, and then the guide trolley is pushed out directly; a fixed suspending arm installed in a production plant is used for loading the nylon cloth on the guide trolley, and then workers push the guide trolley into the locking mechanism for locking so as to complete the nylon cloth loading; in the whole process, the guide trolley is convenient to move, is low in labor intensity, and meanwhile can be used for reducing the safety hazards, and improving the working efficiency.
