在API-Spec.2C的 Onboard Lifts 中提到下面的陈述，

However, Cv shall not be less than 1.1 + Av or greater than 1.33 + Av.
Cv is the dynamic coefficient;Av is the vertical boom tip acceleration expressed in g’s; andFL is the factored load expressed in lb.
当一个需要满足API Spec.2C的SWL 200T Crane 在做FAT和HAT时，Dynamic Overload Test 的载荷是应为200Tx1.1 还是200Tx1.33.

期待高手解惑，小弟对这句话不太理解 However, Cv shall not be less than 1.1 + Av or greater than 1.33 + Av.

不小于1.1+Av，且不大于1.33+Av。

一般最小取 1.33
CV经常会算到 2.几或 3.几
