The invention discloses an anti-rope-breaking protection device for a heavy-load trolley. The anti-rope-breaking protection device comprises a brake lever (2) and a weight mounted at the tail of the brake lever (2), wherein a pulley block (3) is further arranged at the end in which the weight is arranged; a traction steel wire rope penetrates through a clamping grove of a pulley of the pulley block (3), and can drive the pulley to rotate in a normal working process; and an anti-releasing shaft (4) transversely penetrates through the lower part of the pulley and is used for preventing the traction steel wire rope from being released from the pulley. According to the anti-rope-breaking protection device disclosed by the invention, one nylon pulley block is additionally arranged and the traction steel wire rope can relatively move in a pulley groove; and the abrasion degree caused by the direct contact friction of the traction steel wire rope and the anti-rope-breaking device is greatly reduced and the possibility that the steel wire rope is abraded to be broken is effectively avoided.
