The machine is used in civil engineering. It consists of twopairs of vertical spacers (4 & 5; 6 & 7) being smooth metal tubesor rails, fixed to the base along the height of the machine.Laterally and externally the spacers are fitted opposite to twohorizontal axles (8 & 9) on which a central (12 & 13) and two end(14) 15; 16 & 17) bearings, each, which roll are mounted over thespacers. A steel horizontal space (1) is fitted at the height ofthe machine at one of the ends of which a rope (2) is connected,and a fixed pulley (3) being mounted at its other end. Cargo (24)is suspended with slings (20, 21) on the axle found at the fixedend of the rope which in this way is brought near to the maximumto the dynamically changing fulcrum on the fixed end of the rope.In operation the rope goes over the central bearings (12, 13) ofthe axles, then over the groove of the fixed pulley (3) and endsat the driving force (25).1 claim, 1 figure
