Full Description

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.

All current amendments available at time of purchase are included with the purchase of this document.
