A lifting device for lifting a payload within an elevator shaft in a controllable manner has a platform to be fixed in the elevator shaft, a holding device to be fixed to the payload, a lifting cable attached to the holding device, a securing cable secured to the holding device (such as, for example, a pulling device secured to the platform), and a catching device secured to the platform. The pulling device actively and controllably displaces the lifting cable relative to the platform. The lifting device displaces the securing cable in the event of a relative movement between the holding device and the platform such that the securing cable remains tensioned. The securing cable and the catching device are configured such that the catching device blocks a further relative movement between the securing cable and the catching device in the event that the lifting cable fails.
