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 is 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.

In a hoist for a low space crane which is mounted on a guide rail installed at a girder and moves along the guide rail for thereby transferring a certain weight object, a hoist for a low space crane, comprising:
- hoist frames which are arranged so that a load point P transferred to the girders is positioned at a vertical surface of one side of each girder, and the balance of biased load is maintained, for thereby decreasing the entire load;
- and
- an equal distribution unit which is installed between the hoist frames and absorbs the impact load transferred to the hoist frames and equally distributes the entire vertical weight load.
