Abstract (en)

[origin: WO2015071555A1] An elevator system (1) comprising a car (2), a counterweight (3) having a counterweight mass value (Mcp) strictly less than the mass of the car plus half the maximum loading mass, and a control device (9) comprising receiving means for receiving a current loading measured value (Qmes), processing means for calculating a speed value depending on the current loading measured value, and transmission means for transmitting a control signal so as to cause the car to move at the calculated speed, and two pulleys (4, 5) intended to be installed at the respective ends of the elevator shaft, wherein at least one of the car and the counterweight is mounted on at least one linear element (4) that passes via the two pulleys so as to form a closed loop with said at least one of the car and the counterweight.
