The work of preparing In

Each member body interested in a subject for which a technical committee has been established has the right to be represented on that committee. International organizations, govern- mental and non-governmental, in liaiso

Draft International Standards adopted by the technical committees are circulated to the member bodies for approval before their acceptance as International Standards by the IS0 Council. They are approved in accordance with IS0 procedures requiring at least 75

9、ng and gantry cranes. 1 Scope and field of application This part of IS0 4301 establishes a classification of mobile cranes and related crane mechanisms based on the number of operating cycles to be carried out during the expected life of the mobile crane or mechanism and on a load spectrum factor wh

It applies to basic types of self-propelled mobile cranes and their parts as defined in IS0 4306/2. 2 References IS0 4301, Lifting appliances - Classification.
