The invention discloses a lifting process for large equipment. The lifting process comprises the following steps that 1, the large equipment to be lifted is connected with a preinstallation frame, and all infrared transmitters are arranged on the preinstallation frame in the mode that the infrared transmitters can transmit infrared light paths perpendicular to the plane where the preinstallation frame is located; 2, a preinstallation position defined by a closed standard outline is provided in an operation area, a butt joint frame is installed on the standard outline, and every two neighboring infrared receivers are abutted against each other; 3, a controller is provided; and 4, the large equipment is lifted to the position above the operation area with lifting equipment, the position of the large equipment is adjusted until the controller receives signals of n infrared receivers at the same moment, the controller sends a prompt message, the large equipment is put down according to the prompt message, and the controller sends the prompt message throughout the putting down process. According to the lifting process for the large equipment, the position where the large equipment falls back finally coincides with the preinstallation position.
