ABSTRACT In a method for checking and monitoring the friction between the traction sheave and the suspension ropes of an elevator, the slippage between the traction sheave and the suspension ropes of the elevator is measured, the elevator comprising an elevator machine, a hoistway and an elevator car and a counterweight moving in the hoistway. The rope slippage is measured either periodically by performing test drives or continuously by means of an impulse device placed in the elevator machine and measuring the motion of the traction sheave, an impulse device monitoring the movement of the elevator car and an impulse device monitoring the load in the car. The data provided by these impulse devices is transmitted to a computer which calculates and monitors the relative slippage between the traction sheave and the suspension ropes of the elevator.
