Final answer:
The correct minimum weight lifting inserts attached to tilt-up wall panels must support is not provided in the reference material, and it's recommended to consult relevant building codes or industry standards.
Step-by-step explanation:
The question of how much weight lifting inserts attached to tilt-up wall panels must support does not have a direct answer within the provided reference material. However, given the context, this question is likely sourced from industry standards or specific regulations that define safety requirements for construction materials and equipment. In the construction industry, these inserts are designed to handle significant loads, often way beyond the options provided (500 lbs, 1,000 lbs, 2,000 lbs, and 3,000 lbs). Since the supplied materials do not contain the specific weight requirement for these lifting inserts, I cannot confidently provide the correct answer. It is recommended to consult the relevant building codes, engineering standards, or manufacturer specifications to determine the minimum weight capacity for lifting inserts used in tilt-up wall panel construction.
