Resumen

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.
