Abstract

The invention relates to a traction sheave elevator (10), having an elevator car (12) and a counterweight (14) suspended on elevator ropes (16). The elevator has an elevator controller which has at least one door controller connected to a door status indicator (32) indicating the status of the car door. According to the invention at least one load weighing device (24, 28) measures a force of the elevator ropes (16), and the elevator controller has a load determination logic calculating the car load from the output signal of the load weighing device. The load determination logic performs a calibration run by measuring the output signal of the load weighing device (24, 28) at two specified different height levels of the elevator car (12), whereby the car door is monitored to be continuously closed during the calibration run. The load determination logic (30) determines from the two measurements the car position dependency of the output signal of the load weighing device (24, 28) for calculating a car load value.
