On March 11, it was reported from the construction site of the Maoming Petrochemical project that the lifting operation carried out by Petrochemical Shipping Company was successful: the vertical section of the pressure reduction orifice plate for this project was lifted and passed over the various equipment and frames, being precisely placed above the steel structure. The entire process was carried out with \"zero deviation and zero risk,\" demonstrating the company’s professional technical expertise and ability to organize such large-scale lifting operations effectively. This critical equipment is part of the steel structure framework; it weighs 201 tons, has a diameter of 2.5 meters, and a length of over 30 meters. Regarding the implementation of equipment lifting, the project’s engineering technicians carried out preliminary layout work and conducted repeated site inspections in advance. They organized discussions among all relevant parties to develop the lifting plan, and facilitated thorough pre-lifting simulations, safety briefings, and inspection procedures involving the owner, supervisor, general contractor, and construction units, to ensure that every aspect of the lifting process was safe and under control. At the command of the chief commander, the 4,000-ton crawler crane began to lift slowly, with the 400-ton truck crane working in coordination to enable the pressure-reduction orifice plate to rise smoothly off the ground. When the equipment is lowered into the steel structure, the operator, relying on their extensive experience and working closely with the lifting supervisor, slowly lowers the equipment until it is precisely delivered to its installation location, ensuring accurate positioning. The equipment lifting process was safe, controllable, precise, and efficient, demonstrating excellent lifting skills and construction organization capabilities.
