Abstract
This paper describes an innovative mechanism based on hydrostatic pads and linearmotors for the elevation structure of next-generation extremely large telescopes. Both hydrostatic pads and linear motors are integrated on the frame that includes a kinematical joint, such that the upper part is properly positioned with respect to the elevation runner tracks, while the lower part is connected to the azimuth structure.

Potential deflections of the elevation runner bearings at the radial pad locations are absorbed by this flexible kinematic connection and not transmitted to the linear motors and hydrostatic
pads. Extensive simulations using finite-element analysis are carried out to verify that the auxiliary whiffletree hydraulic design of the mechanism is sufficient to satisfy the Q3 assigned optical length variation errors.
