Single-tower asymmetric cable crane

The invention discloses a single-tower asymmetric cable crane. The single-tower asymmetric cable crane comprises an east bank anchor arranged on a mountain of a valley east bank, a tower frame arranged on a valley west bank lower than the valley east bank in terrain, and a west bank anchor arranged on a mountain of the valley west bank on the back side of the tower frame; a bearing cable spanning over a valley is tensioned between the east bank anchor and the west bank anchor by spanning over the tower frame; a lifting pulley is arranged on the bearing cable, and is provided with a towing cable and a lifting cable; the towing cable is connected to a towing windlass arranged on the valley east bank and/or the valley west bank; and the lifting cable is connected to a lifting windlass arranged on the valley east bank and/or the valley west bank. According to the single-tower asymmetric cable crane, the bearing cable on the valley east bank is directly anchored in the mountain of the valley east bank; the tower frame is arranged on the side of the valley west bank; and the bearing cable passes through the tower frame to be anchored on the mountain of the valley west bank. The cable tower construction time is saved on construction period; the cost is saved on economy; and the difficulty of incapability of setting a cable tower is solved on construction difficulty.
