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.
Tower cranes for construction work are exclusively equipped with a hook as the load-handling device.
For tower cranes intended to be used for other purposes and/or with other load-handling devices, other values can be necessary according to the tower crane usage specification.
