Abstract
A procedure and apparatus for the measurement of elevator load uses a load measuring apparatus. The elevator comprises an elevator car (17) travelling along guide rails (2) in an elevator shaft, a counter-weight (20), a hoisting machinery (18, 19), a control unit, and hoisting ropes (11) attached at least by one end to an anchorage (21) in the elevator shaft. The load measuring apparatus (16) comprises a strain gauge (15) which outputs an electric signal corresponding to the load. The load measuring apparatus (16) is attached in conjunction with the anchorage (21) of the hoisting rope ends to a fixed place in the elevator shaft.
