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, wherein 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, and wherein each mast part is constructed as a framework structure consisting of angle bars and cross bars mutually connecting the angle bars, wherein 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.
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, wherein 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, and wherein each mast part is constructed as a framework structure consisting of angle bars and cross bars mutually connecting the angle bars, characterized in that the angle bars consist of two parts with a setsquare-shaped cross-section of different dimensions, 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.
Hoisting device as claimed in either of the foregoing claims, characterized in that the connecting means are slidably received in close-fitting manner in the angle bars, which means comprise two identical plate pieces and a filler body arranged therebetween, that at least two holes are arranged in each plate piece, that holes are likewise arranged on the outer ends of the angle bars of each mast part, wherein the holes of the plate pieces lie in each case in one line with two holes of two mutually abutting mast parts for receiving a pin.
Hoisting device as claimed in any of the foregoing claims, characterized in that for transport an auxiliary frame is arranged on each end surface of the mast part, which frame is provided with coupling means corresponding with those of a usual container, wherein the dimension between the coupling means on the one and on the other end surface of the mast part and the dimension between the coupling means on one side of the mast part mutually correspond with those of a usual container.
