The invention relates to a stay rope type loading and unloading device for a truck. The stay rope type loading and unloading device is mounted at the tail of a carriage of the truck and comprises a carriage tail board, a lifting mechanism, a lifting transmission mechanism and a turnover transmission mechanism. The carriage tail board is in a horizontal state when the stay rope type loading and unloading device is used for loading and unloading; the carriage tail board can be driven to ascend or descend under the effect of the lifting transmission mechanism; the carriage tail board ascends to reach the tail of the carriage of the truck when loading and unloading are completed, and the carriage tail board and the tail of the carriage of the truck can be fittingly closed under the effect of the turnover transmission mechanism. The stay rope type loading and unloading device has the advantages that the lifting mechanism is a motor and worm-gear and worm mechanism, and accordingly the cost can be greatly reduced; worm gears and worms have self-locking functions, and accordingly the carrying safety can be guaranteed; the carriage tail board can be opened as needed by the aid of a reset mechanism without starting motors, and reset springs can be compressed when the carriage tail board is closed; reset pins can pop out when a turnover stay rope is loosened, so that the carriage tail board can be opened by a certain angle and then can be automatically opened owing to the dead weight of the carriage tail board.
