One rope and one valve are mistaken for complete protection

A fictional elevator review lists several suspension ropes and a hydraulic equipment diagram from a different installation. A trainee concludes that every rope can independently carry the entire rated load and that any check valve is a complete safeguard against a ruptured line. Another person treats a brake, governor and buffer as interchangeable names. The actual design, equipment ratings and protection functions have not been established. No elevator is moved, no valve is operated and no person enters a hoistway in this exercise. Explain which assumptions are unsupported and identify the need to follow the actual load path, distinguish functions and obtain the competent manufacturer and applicable-code basis before making a real technical conclusion.
