1. A platform system (5) for use in a cargo compartment of a truck, lorry or trailer (1), the platform system comprising:
at least one elevation platform (20,20′,20″,71) with a substantially rectangular outline, onto which, in use goods can be loaded, the at least one elevation platform (20,20′,20″,71) being guided by a plurality of horizontally spaced and vertically extending guides, preferably four vertically extending guides, each at least one elevation platform (20,20′,20″,71) being suspended from a set of cables (16rb,16rf,16lb,16lf, 16rb′,16rf′,16lb′, 16lf′,16rb′,16rf″,16lb″,16lf″,81), at least one hydraulic actuator (25,25′,25″,82), said at least one hydraulic actuator being associated with said at least one elevation platform (20,20′,20″,71), and a second end of a cable in a said set of cables being operably connected to said at least one actuator (25,25′,25″,82); and wherein cables in a set whose first ends are connected to one and the same side of an elevation platform (20,20′,20″,71) form a subset and are joined at a position and continue from that position towards the actuator as one cable; and one end of the hydraulic actuator (25,25′,25″) is secured to—and supported by said frame (30) and the other free extremity of the hydraulic actuator (25,25′,25″) is provided with two cable wheels (29l,29r), and wherein the cable connected to a subset of cables that is connected to one side of an elevation platform is guided around the one of the two cable wheels and the second end of the cable connected to a subset of cables that is connected to the other side of the same elevation platform is guided around the other of the two cable wheels (29l,29r). |
