The invention relates to a lifting limiting control system, a hoisting mechanism and a crane. The lifting limiting control system comprises a photoelectric rotation detection device and a limiting controller, wherein detection signals generated by the photoelectric rotation detection device are transmitted to the limiting controller; the photoelectric rotation detection device is provided with a to-be-detected rotation disk assembled with a corresponding shaft of a speed reducing mechanism, and a static bracket for detection; the static bracket is over against the rotation disk and is equipped with a photoelectric switch; the photoelectric rotation detection device is provided with at least one detection unit; each detection unit consists of an eccentric hole formed in the rotation disk, and a group of photoelectric switches arranged on the static bracket; and the photoelectric switches are distributed on corresponding arc lines of the eccentric holes and used for transmitting the detection signals. The size of the whole photoelectric rotation detection device is reduced, the device is convenient to mount, and the lifting limiting control system operates reliably.
