At present, the policy basis for the early retirement of employees of state-owned collective enterprises due to special types of work is still the Notice on Printing and Distributing (Guo Fa [1978] 104): "The employees of enterprises and institutions owned by the whole people, party and government organs and mass organizations are engaged in underground, high altitude, high temperature, particularly heavy physical labor or other jobs harmful to health, and they are male and female. In the identification of special types of work, the relevant types of work are distinguished by industry in strict accordance with the practical catalogue of special types of work. The crew you mentioned did not indicate the nature of the unit and the name of the industry, so it is impossible to simply determine whether it meets the conditions for early retirement of special types of work. You can also consult the administrative department of the people's society of the insured place.
