The invention provides a fixed crane convenient to disassemble. The fixed crane comprises a base, a jib, a pull rod, an A frame, a hoisting mechanism, an amplitude variation mechanism, a rotational mechanism, a rotary table and a lifting appliance, wherein the base is detachably fixed onto a pedestal; a rotational support is arranged at the top of the base; the rotary table is mounted on the rotational support of the base and can rotationally move by 360 degrees; the A frame is mounted on the rotary table; the top end of the A frame is rotationally connected with one end of the pull rod; a pull rope is arranged on the pull rod, and the pull rod is connected with the top end of the jib through the pull rope; the lifting appliance is suspended at the top end of the jib; the tail end of the jib is rotationally connected with the rotary table; the hoisting mechanism, the amplitude variation mechanism and the rotational mechanism are mounted on the rotary table; the hoisting mechanism is connected with the lifting appliance on the jib through a lifting rope; the amplitude variation mechanism is connected with the pull rope on the pull rod to control the amplitude of the jib; the rotational mechanism is connected with the rotational support on the base. The fixed crane convenient to disassemble is flexible and convenient to use, high in safety and low in limitation.
