The invention discloses a novel luffing rib ropewalking crawler crane. An integrated guide pulley device is arranged on a luffing rib rear support, and a luffing wire rope is output from a luffing hoist, reaches the integrated guide pulley device on the luffing rib rear support to change the direction of the rope, rises in the luffing rib rear support, reaches to a pulley group at the head of the luffing rib rear support, and then is sequentially wound on a luffing rib front support and the pulley group at the head of the luffing rib rear support; and a lifting wire rope output by a lifting hoist sequentially passes through the integrated guide pulley device and a front lifting wire rope guide pulley device arranged on the luffing rib front support, and finally reaches a luffing rib head guide pulley. The versatility of arm knots of a principal arm can be enhanced without the luffing rib luffing wire rope guide pulley device, so the processing and dismounting complexity is reduced, and the weight of the head of the principle arm is reduced, thereby the overturning moment of the whole crane is reduced, and the arm is easy to lift.
