The present invention discloses a crane for outdoor installation. The present invention includes a front plate fixed to one side of the upright support through a bolt and nut, and a fixing plate consisting of left and right brackets which are bent vertically from both left and right sides of the front bracket and face each other; A first fixing shaft fixedly installed between the left and right brackets of the fixing plate; A rotating plate rotatably supported on the first fixed shaft and having a body on which a rope is wound around an outer circumferential surface thereof, and a flange provided on both left and right sides of the body to block detachment of the rope; Located in parallel with the upper part of the first fixed shaft, both ends are rotatably supported on the left and right brackets of the fixing plate, and a rotating gear is fixedly installed on one side, and the outer both ends protrude outward of the left and right brackets. The rotating shaft is provided with a handle for rotation; A transmission gear meshed with the rotary gear of the rotary shaft to rotate and fixed to an outer side of the flange of the rotary plate to transmit the rotational force to the rotary plate; A second fixing shaft positioned on the upper side of the rotating shaft and fixed at both ends on the left and right brackets of the fixing plate; A breaker positioned on a second fixed shaft corresponding to the rotary gear of the rotary shaft, and providing a rotational force in only one direction and controlling the rotational force in the other direction when the rotary gear rotates clockwise and counterclockwise through the handle; It is characterized by that, including the upper and lower contact table, such as a flat ceiling surface or window frame, all the parts are installed in a stable and unstable support, so that the operator can more certainly prevent the occurrence of safety accidents caused by falling in the course of work.
