The invention relates to the technical field of balance cranes, and discloses a pneumatic balance crane based on a movable pulley, the pneumatic balance crane comprises a balance crane body, the balance crane body comprises a first shell and a second shell, the adjacent ends of the first shell and the second shell are fixedly connected, a first cavity is formed in the first shell, and a second cavity is formed in the second shell. A first cavity is formed in the first shell, a second cavity is formed in the second shell, the first cavity communicates with the second cavity, a second end cover is fixedly installed at the end, away from the second shell, of the first shell, a first end cover is fixedly installed at the end, away from the first shell, of the second shell, and a piston rod is movably installed in the second cavity. According to the pneumatic balance crane, the piston rod in the shell of the pneumatic balance crane moves to push the piston rod to achieve movement of the pulley, then the lifting steel cable is lifted and lowered to achieve lifting and lowering of an object, the control valve is manually operated to adjust pressure applied to the piston rod, and then the effect of a lifting machine is achieved during working.
