A crane carriage (1) has a lower support assembly (15) with three guide wheels (9,11) which run on rails (3,5). The carriage also has an upper support assembly (17) with an arm (20) and a winch drum (31). The winch is light weight, because the flanges of the winch drum are at a distance equal to fifty times the diameter of the winch cable (43).
