Abstract (en)

[origin: EP1870370A1] A car and a counterweight are suspended within a hoistway by amainrope. A driving machine for moving the main rope to raise/lower the car and the counterweight is provided within the hoistway. The driving machine has a driving machine main body and a contact roller. The driving machine main body includes a rotor penetrated by the main rope serving as a penetration body. The contact roller is provided on the rotor, is in contact with the penetration body, and can rotate around a rotational shaft that is inclined with respect to a center line of the penetration body when the contact roller is vertically projected onto the penetration body. When the rotor is rotated, the contact roller is thereby so rolled as to leave a spiral trace on an outer peripheral surface of the penetration body while being in contact with the penetration body. When the contact roller is rolled while being in contact with the penetration body, the main rope is thereby moved with respect to the driving machine in a longitudinal direction of the main rope.
