A portable crane that essentially consists of an arm supported by its midpoint in a column on which it can swing, which, in turn, is fixed on a movable foot. The inclination of the arm is made by a fixed chain at the foot of the crane and at one end of the arm itself while at the other end of the arm is the pulley from which the hoist hangs passing the cable by a second pulley arranged in the upper part of the support column to a winding drum which is located in the middle of said column.
