A hoisting device for big loads, comprising at least one hoisting mast, a foot arranged on the underside and hoisting means connected at least to the top. The hoisting device is assembled from mast parts which are mutually connectable by means of connecting means and the largest of which has dimensions which do not exceed those of a usual container. Each mast part is constructed as a framework structure consisting of angle bars and cross bars mutually connecting the angle bars. The angle bars consist of two parts with a set-square-shaped cross section of different dimensions and wherein the outer ends of the legs of the smaller lie against the legs of the larger and the larger part lies on the outer periphery of the mast part, so that mast parts are provided of the greatest possible strength and stiffness within the dimensions of typical containers.
