Abstract: In this paper，a design scheme of mooring tower for mobile tethered balloon is discussed．The scheme includes structure form，material，technics options，“three proof”design instrument，etc．Through setting up structure model of mooring tower using finite element method，the stiffness and intensity are analyzed．The result shows that this scheme meets using requirements completely．Besides，the design scheme of electromotor lifting mechanism with helix drive manner is discussed．As an important reference for engineering realization of lifting mechanism，the minimal load and power required in lifting process are calculated．
