<p>The system has vertical, transverse, and longitudinal frames perpendicularly coupled to each other to form a main structure body (200). One side of the body has transverse tracks, and other side has a loading and unloading area for land transportation. The longitudinal frames have a bridge crane on the upper side of the body. A local gantry crane extends between the longitudinal frames and travels in a structure unit.</p> |
