Figure 3: Types of hexapod translators for OVLA and larger elements. 6 pendular legs can be used, 3 of which carry the load ST and translate it at constant height while the others step forward. The constant height may be maintained (middle) with a cam C, the leg being guided by a sliding swivel SR; or (right) by a sliding articulation SL. Both leg mechanisms are compatible with bi-dimensional mobility and rotation. Pre-aligned posts can serve as foot-steps, or the natural ground can be used directly if the legs are equipped with automated levelling pads.
