Embodiments of a solar table mobile transport with collapsible manipulators are described. The collapsible manipulators may be scissor lifts, direct lifts, or pivot lifts, that couple to a torque tube of the solar table and provide at least vertical movement of the solar table. Once the mobile transport approaches an installation spot between installation piles, the mobile transport lifts the solar table by unfolding the collapsible manipulators such that that solar table may cross the pile line and the mobile transport can maneuver between the installation piles. The compactness of the mobile transport, especially when the collapsible manipulators are vertically installed, greatly enhances the maneuverability of the mobile transport within the limited space between the piles. Such a capability of mobile transport maneuverability in combination of solar table alignment facilitates an installation efficiency of the solar table.
