ISO/TC 96/SC 7 - Tower cranes

This document provides the classification of tower cranes for construction work as defined in ISO 4306‑3, and gives specific requirements for steel supporting structure, mechanisms, ropes and further components basing on standard service conditions, mainly expressed by the following: — the number of working cycles; — the load spectrum factor; — the average displacements; and — additional values for factors to be used at the structural or mechanical calculation. Tower cranes for construction work are exclusively equipped with a hook as load-handling device. For tower cranes intended to be used for other purposes and/or equipped with other load handling devices, other values according to the specified usage of the tower crane may result.

This document establishes required practices for the safe use of tower cranes. Subjects covered include safe systems of work, management, planning, selection, erection and dismantling, special base, operation and maintenance of cranes and the selection of operators, slingers and signalers. It does not cover manually (non-powered) operated cranes, or cranes in which at least one of its motions is manually operated.

This document specifies the minimum requirements for labels for the identification (marking) and the operation of tower cranes.

This document specifies the regular inspections to be carried out on tower cranes. It does not cover inspection prior to the first use of a tower crane.

It is not applicable to end stops such as buffers used to stop trolleying, travelling or luffing movements, nor to erection, dismantling operations or the changing of a crane's configuration. NOTE General requirements for the devices are given in ISO 10245‑1.

This document establishes the application of ISO 8686-1 to tower cranes for construction work as defined in ISO 4306-3, and gives specific requirements and values for factors to be used at the structural calculation.

ISO 10972-3:2003 establishes requirements which apply specifically to the mechanisms and related components of tower cranes, in addition to the general requirements given in ISO 10972-1. These additional requirements concern the arrangement, features and characteristics of the crane mechanisms, and the minimum requirements for certain mechanism components. Rules for the proof of competence calculation regarding different limit states (yield strength, fatigue, wear) are excluded from ISO 10972-3:2003. ISO 10972-3:2003 is not applicable to the climbing mechanisms and related components used on tower cranes, nor to the climbing frame.
