Hello,

General

Annex 8 is applicable both to hoist mechanisms as an integral part of a crane and to serial hoist units with a given class of mechanism.

Two basic duty factors and the class of mechanism as a combination of the two duty factors are dealt with as follows:

total operation time, T;

load spectrum factor, Km, representing the state of loading, L, of the mechanism;

class M of the mechanism as a combination of the two duty factors.

In cases where separate design limits for the basic duty factors (T, Km) are known (e.g. for a purpose built crane), the DWP calculation shall be based on those factors according to Clause 8.2. In cases where the mechanism classification only is known, the DWP calculation shall be carried out according to Clause 8.3.


Can “are dealt with” in “Two basic duty factors and the class of mechanism as a combination of the two duty factors are dealt with as follows” be interpreted as “are discussed” or “are presented”?

What is your opinion?
