Enhancing the transport capacity of an elevator system

Abstract

An elevator system (2) comprises a hoistway (4) extending between a plurality of landings (8a, 8b, 8c); an elevator car (60) configured for moving along the hoistway (4) between the plurality of landings (8a, 8b, 8c); a load/weight sensor (44) configured for detecting the load of the elevator car (60); a speed detector (34) configured for detecting the speed of the elevator car (60); and an elevator safety system. The elevator safety system comprises a safety gear (20) configured for stopping, upon activation, any movement of the elevator car (60); and an electronic safety controller (30) configured for activating the safety gear (20) when the detected speed of the elevator car (60) exceeds a set speed limit. The electronic safety controller (30) is configured for setting the speed limit as a function of the load detected by the load/weight sensor (44).
