The present invention is a unified spine structure that EFEM components, such as a wafer handling robot and a SMIF pod advance assembly, may mount to. The bridge support is mounted to the lower side of bent limb portions of the central tunnel and is connected via at least two bolted connections, which are offset in the longitudinal and transverse directions of the vehicle, to a supporting bracket arranged on the upper side of the bent limb portions. On the air chamber peripheral wall 3i are protrusively formed a plurality of rib-shaped projections 15 each forming a thick portion for reinforcement. A resilient member biases the body and slide in one direction. The under support has its largest width, thereby the largest contact surface with the implant, closest to the lateral end causing the implant to be supported upward and medially. The controller comprises software that transfers the location data to and from the RAGPS receiver and a RFID assistance tag.
