After 3 years of work HWS has finished the demonstrator of the self-climbing AirCRANE, a 30 t net-lifting capacity unit. Once the technology/concept has been tested and validated, HWS is confident in scaling it up to 250 t or down to 5-10 t (for construction).
In this type of cranes two concept should be distinguished:
In the case of the AirCRANE: -> The climbing process is mechanical, based on three innovative devices which moves along the main girder. This innovative concept introduces the possibility to climb along vertical surfaces with trunk transitions, irregularities, inclined walls, etc. -> The anchoring system is conducted by means of a pair of spikes that are inserted into some cavities left in the tower. A reliable anchoring can be assured relying mainly in gravity force.
