摘要

Heavy machinery-carrying structure incorporates three cylinders each with two drilled plates (1) and countersunk, with sockets and provided with lower rounded vertices and indented upper side between two perforated projections. The plates also have bolts (2) in the sockets, external bearings (4) with nylon wheel (4.1). An upper socketed piece locates and fixes a horizontal bearing, which provides an axial location for the support of the machinery.
