Abstract
The present invention relates to an elevator and a method for measuring the load in an elevator, in which the elevator car is suspended on hoisting ropes with at least one upward-directed diverting pulley or diverting pulley pair, from which the elevator ropes go upwards on both sides, and at least one downward-directed diverting pulley or diverting pulley pair, from which the elevator ropes go downwards on both sides. In the elevator at least one upward-directed diverting pulley or diverting pulley pair and at least one downward-directed diverting pulley or diverting pulley pair is fixed to the elevator car with a shared supporting structure. In the method the tension information is measured from a supporting structure and a load-weighing signal is formed using the tension information obtained.
