    Abstract: The object of the invention is a method for modernizing an elevator, and a traction sheave elevator, which elevator comprises at least an elevator car and a traction sheave that moves the elevator car by means of elevator ropes, the rim of which traction sheave comprises one or more rope grooves. In connection with modernization a traction sheave is installed as the traction sheave of the elevator, the rope grooves of which traction sheave comprise a material, the frictive traction achieved by which is greater than the frictive traction between the parent material of the metallic traction sheave and the elevator ropes.

    Abstract: The invention relates to an elevator system and also to a method for ensuring the safety of an elevator system. The elevator system comprises a driving member (1) and also a hoisting means (3), which engages with the aforementioned driving member (1) by frictional traction. The elevator system comprises traction determination means (4, 5, 6A, 6B, 7) for determining the traction of the driving member (1), and the elevator system comprises a control circuit (4), which is configured to start a procedure ensuring the safety of the elevator system after the traction determination means (4, 5, 6A, 6B, 7) have detected that the traction of the driving member (1) has weakened.

    Abstract: The object of the invention is a suspension arrangement of an elevator car, which elevator car (1) is fitted to travel moved in an elevator hoistway by a traction sheave on essentially vertical guide rails (2) supported by elevator ropes (3), and in connection with which elevator car (1) is a plurality of diverting pulleys (4-7, 10, 11). The diverting pulleys (4, 7, 10) that support the elevator car (1) are disposed on the sides of the elevator car (1), essentially on the bottom edge of the elevator car (1).
