摘要

A method and apparatus are disclosed for the measurement of load in an elevator car. An elevator system comprises the elevator car travelling along guide rails in an elevator shaft, a counterweight, hoisting machinery, a control unit, and hoisting ropes attached by at least one end to an anchorage in the elevator shaft. The load measuring apparatus comprises a strain gauge which outputs an electrical signal corresponding to the load. The load measuring apparatus is attached in conjunction with the anchorage to a fixed place in the elevator shaft.
