Abstract: A method for detecting an overload condition of an elevator car of an elevator includes obtaining prevailing car-load information from a load weighing device arranged to weigh a prevailing car-load preferably when the elevator car is standing at a landing floor in an elevator shaft; determining if said prevailing car-load information fulfils one or more overload criteria; and generating a signal indicating an overload condition of an elevator car, if said car-load information fulfils one or more of said overload criteria; obtaining information of at least one operational parameter of the elevator; and adjusting one or more of said overload criteria or said car-load information based on said information of the at least one operational parameter of the elevator. An overload monitoring system and an elevator implementing the method are also disclosed.
