The invention discloses an elevator weighing device. The elevator weighing device comprises an electric system and a traction system connected with the electric system. The traction system comprises a tractor and a brake wheel; the brake wheel is wound with a hauling rope; the hauling rope drives the brake wheel to rotate; one end of the hauling rope is connected with the top of an elevator car; the other end of the hauling rope is connected with an elevator counterweight; a weighing device is arranged at the bottom of the elevator car and connected with a car system; the weighing device comprises an elastic component; the lower portion of the elastic component is connected with pressure sensors; a micro-touch switch is arranged below the pressure sensors. The car system comprises an elevator door controller connected with the micro-touch switch. As the elastic component is stressed and deformed downwards, the pressure sensors move downwards to trigger the micro-touch switch below the pressure sensors, it is achieved that the elevator door controller is started when an elevator overloads, and an alarm is given through a voice reminder. The structural design is simpler and more reasonable, flexibility is high, manufacturing cost is low, and fitness is wide.
