The invention relates to an elevator car load mass measuring method, device and equipment, a medium and a product. The method comprises the steps that in the elevator running process, a first electric signal is collected for a traction motor in a transmission system of an elevator; the transmission system comprises a traction motor for controlling the lift car to lift, the lift car, a counterweight and a rope; based on the first electric signal, the value of the current motor power of the traction motor, the value of the current running speed of the lift car, the current running state of the lift car and the current value of the running height between the position where the lift car is located and the reference position are determined; obtaining a pre-fitted steady-state parameter value and a pre-generated rope parameter value; and when the running state is a constant-speed running state, the current load mass value of the lift car is determined according to conservation of input power and consumption power of the transmission system and according to the current motor power value, the current running speed value, the steady-state parameter value, the rope parameter value and the current running height value. By adopting the method, the car load mass measurement precision can be improved.
