The present application provides a pit leveling device (100) for elevators, a leveling method and an elevator system. The pit leveling device comprises: a base (110) having supporting portions (111) and a plurality of supporting feet (112), wherein the plurality of supporting feet are detachably disposed below the supporting portions; a plurality of lifting devices (120) disposed below the supporting portions for pushing the supporting portions away from at least a part of the supporting feet during an upward movement; and height compensators detachably disposed in gaps where the supporting portions are pushed away from at least a part of the supporting feet by the lifting devices. This configuration can enable adjustments to be made properly according to the actual levelness of the pit at the elevator installation site, so as to ensure the levelness of the pit, thereby providing a level and reliable installation foundation for the entire hoistway frame to be set up on the pit.
