Hoisting device comprising a boom (2) and a mast (3), both with one end pivotably arranged to each other, a counterweight (5) attached to the free end of the mast (3) and a lifting device connected to at least the free end of the boom (2), wherein said free end of the mast (3) and said free end of the boom (2) are connected by cables (17), characterized in that:
- the hoisting device is assembled from components or elements, the largest of which has dimensions which do not exceed those of a standardized sea container of an 8 foot by 8 foot by 40 foot size;
- both pivotably arranged ends of the boom (2) and mast (3), respectively, are pivotably arranged to a support plate (12, 24), which is supportable on the same base, not a part of the hoisting device, as the counterweight (5);
- and at least some of said elements include couplings corresponding to a standardized sea container, to enable said some of said elements to be handled during transport in the same manner as standardized sea containers, said couplings being part of said some of said elements when the hoisting device is assembled in a use configuration and when the hoisting device is disassembled for transport.
