Abstract: Disclosed therein is a collapsible crane capable of being transported by a container which includes a girder including a first girder of the left side, a second girder of the right side and a third girder of the middle side, the first girder and the second girder are detachably connected to flanges of the both ends of the third girder, and components mounted on the first girder, the second girder and the third girder are collapsed to come into contact with the first girder, the second girder and the third girder.

Abstract: Disclosed is a hoist using a friction wheel to maximize horizontal movement of a load to be lifted while preventing a wire from deviating from a winding orbit while being wound on a wire drum, the friction wheel having a simplified configuration and being designed to stably support horizontal and vertical movable guide rollers. The hoist includes a single friction wheel on which a wire at a winding side is wound, a wire drum on which the wire at a drawing side is wound, a driven friction wheel through which the wire is guided from the friction wheel to the wire drum, vertical and horizontal stationary guide rollers and vertical and horizontal movable rollers for guidance of the wire, a movable roller mount to horizontally reciprocate the horizontal and vertical movable guide rollers, and upper and lower sheaves to guide the wire to the friction wheel.

Abstract: A turning device for a hoist is disclosed, in which a weight thing with a narrow width can be stably turned with a stable support. A rope end unit or an upper sheave unit is easily installed at a hoist frame. A rope end unit or an upper sheave unit is installed in a hoist frame and is freely movable in opposite positions.

Abstract: A hoist for a low space crane is disclosed, which comprises a hoist frame in which a load point transferred to a girder is positioned at a vertical surface of one side of the girder, and a balance of a biased load is maintained for thereby decreasing an entire weight of the system, and an equal distribution unit which installed between the hoist frame and the guide rail for absorbing an impact load transferred to the hoist frame and equally distributing the entire vertical load. A buckling phenomenon does not occur at the girder even when a relatively heavy object is transferred by providing the first and second support wheel parts on the first vertical surface of the girder.

Abstract: An ironing board comprising a preferably height-adjustable stand whose upper end supports an ironing surface, wherein the stand has two hinged legs, and each leg has a foot section that rests at least partially on the base with the ironing board set up, and each leg additionally has a lower section that extends from the foot section to the mid section of the leg, wherein the mid section of the leg extends from the lower section to the upper section of the leg, wherein the upper section of the leg extends from the mid section to under the ironing surface, with the lower section being shaped in such a way as to smoothly flow into the foot section of the leg, wherein the leg is bent by more than 45° in the transitional area between the lower section and foot section, wherein each leg has a first vertex roughly in the area of the hinge linking together the two legs, a third vertex in the transitional area between the lower section and the foot with an angle between the two less than 45°, and a second vert
