Disclosed is a two nodal point pressure-equalising device of steel rope sets for an elevator, comprising a pres - sure-equalising device main body (1); wherein the pressure-equalising device main body (1) is rotatably provided on a base seat (5); two spherical nodal points (8) are symmetrically provided on the pressure-equalising device main body (1); the centre of the spheric¬al nodal points (8) is provided with a through hole (9); the through hole (9) is used for mounting a steel rope; the spherical nodal points (8) can rotate around the pressure-equalising device main body (1); the rotational centre of the pressure-equalising device main body (1) is located on the centre line thereof; and the rotational centre of each spherical nodal point (8) is on the same hori - zontal plane as the rotational centre of the pressure-equalising device main body (1) and is collinear. The device can adjust the pres - sure sustained by two sets of steel ropes, and when a stable state is reached, the pressure sustained by ea
