As a kind of petrochemical catalytic cracking unit, the external heat extractor is one of the key factors restricting the production schedule and time limit. In order to realize the load balance of external heat extractor in the lifting process and avoid the adverse effect of impact force on catalytic cracking performance of large equipment, a method of lifting external heat extractor with tubular balance beam was proposed. At the same time, a kind of seamless steel tube balance beam is designed according to the characteristics of the balance beam and the working conditions of hoisting. Through the stress analysis of the external heat extractor and the strength calculation of the balance beam of seamless steel tube, the rope installation point of the balance beam and the section position of the balance beam are determined, which can provide the theoretical basis and reference value for the failure analysis of large-scale lifting operations and the lifting operations of similar external heat extractor.
