The invention discloses a luffing crane boom and a using method thereof, and belongs to the technical field of cranes. The luffing crane boom comprises a supporting frame, a rotating frame and a steel wire rope, wherein a lifting plate is arranged on the side wall of the supporting frame; a motor and a detection box are arranged on the lifting plate, and the steel wire rope is fixedly connected to the output end of the motor; a first rotating shaft is rotatably connected with the interior of the detection box, and a friction wheel is fixedly connected to the first rotating shaft; the steel wire rope penetrates through the detection box, and is attached to the friction wheel, and a second rotating shaft is rotatably connected with the interior of the detection box; a transmission mechanism is connected between the second rotating shaft and the first rotating shaft, and a first brush is arranged on the second rotating shaft; and a supporting plate is fixedly connected with the interior of the detection box. The luffing crane boom is simple in structure and reliable in work, and the purpose of detecting the lifting weight in real time is achieved through a pressure sensor; the purpose of maintaining the steel wire rope is achieved through mutual cooperation of a first piston and a third piston; and the practicability is improved.
