Masts are guided by anchors, fixed to the building at any time (guided at 2 levels but resting just at one). The masts transmit every erection effort to the building under construction. The lifting of the HWS set, from one level to the next one, can be achieved using the crane or by the “Hydraulic System HWS”.
