Abstract

An apparatus for transporting equipment and a method for the manufacture of the apparatus are disclosed. A method of manufacture may include providing a first platform having a substantially planar first surface. The method may also include providing a second platform having a substantially planar second surface substantially parallel to the first surface. The method may further include mechanically coupling the second surface to the first surface via a plurality of compression springs allowing movement of the second platform relative to the first platform. Additionally, the method may include mechanically coupling a bearing assembly configured to maintain registration of the second platform relative to the first platform.

Claims
