1. Loading and unloading of raw materials: The loading and unloading of sheets should be carried out in accordance with the specific specifications of the materials, and rough handling is not permitted. For palletized boxes, appropriate steel cables should be used based on their weight; loading and unloading can be done using a crane or a forklift. For sheets that are not packaged, they should be lifted one by one or in small groups of up to three sheets, using shims to support them. Then, they can be loaded and unloaded using steel wires via a crane, or directly with a forklift. Round bars or steel pipes should be handled one by one or in bundles, depending on the circumstances; they must not be thrown around carelessly to avoid deformation. For other items such as welding electrodes and flux, they should be loaded and unloaded according to the diagrams provided on the packaging boxes. When lifting stainless steel materials, protective covers should be used around the steel cables to prevent damage to the surface of the materials. Diesel, coal, etc., should be loaded and unloaded according to specific circumstances; rough handling is not permitted. Loading and unloading must be carried out based on the conditions on site, and fire and smoke prevention measures should be implemented. 2. Equipment handling: Encased equipment should be handled in accordance with the instructions on the packaging box, while bare equipment should be lifted using the designated lifting points. It is not allowed to use round steel bars or pipes for rolling transport, nor is it permissible to use any part of the equipment as a lifting point. 3. Loading, unloading, and transportation of product components 3.1 Stainless steel components: When handling stainless steel components, it is necessary to prevent scratches on their surfaces as well as collisions between the components themselves, in order to avoid such damage. Soft fabrics should be used as padding during handling to prevent direct contact with forklifts or other hard objects. Components should be stacked in designated areas in an orderly manner; they must not be left scattered around, as this could lead to them being damaged by vehicles or people. They should also be stacked in a way that complies with specified requirements, so as not to affect the precision of the components. 3.2 Parts made of other materials: They should be handled and stacked neatly to maintain the quality of the machined surfaces; rough handling or throwing is strictly prohibited. They must be stacked in the prescribed manner to avoid affecting the machined surfaces and the precision of the parts. 4. Turning over of components: For larger components, lifting devices should be used whenever possible, especially when such devices are available or temporary lifting arrangements can be made. Before lifting, it is necessary to check that the lifting device is secure and safe; only then can the component be turned over. If lifting devices cannot be used, the component must be turned over in accordance with the specific circumstances and the manufacturing process required for that product. It is important not to handle the component carelessly, as this could lead to damage and render it unusable. 5. Loading and unloading of products: The loading and unloading of products should be carried out using steel cables or forklifts, in accordance with the lifting marks and lifting positions indicated on the packaging, to ensure the quality of the products.
