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.

Abstract: A safety gear (1) comprising a frame provided with a braking surface, which, when the safety gear is braking, is pressed against a first guide surface of a guide rail. Mounted in the frame is a roller (3), which moves along a track in the safety gear. The track comprises at least a first gradient and a second gradient, the first gradient having a larger pitch angle than the second gradient. The roller is pressed against a second guide surface of the guide rail when the safety gear is braking. The roller (3) has a stronger grip on the track on the first gradient than on the second gradient.

Abstract: A sliding safety gear designed to brake by gripping an elevator or counterweight guide rail includes a flexible frame surrounding the guide rail in the directions of the guiding surfaces of the guide rail. The frame is provided with a braking surface that meets a first guide surface of the guide rail when the sliding safety gear is braking. Attached to the frame is a force element that meets a second guide surface when the sliding safety gear is braking. The cross-section of the frame of the safety gear is substantially in the shape of the letter C. At least one of the ends of the jams of the C-shape is inside the C-shape.
