Yard tractor pulls container on chassis into position while crewmen place IBC's on corner castings of bottom container. |
 |
 |
Spreader is positioned over container. Note the IBC's on bottom container. |
Container is "Top-Lifted" by means of inserting steel plugs at the corners of the spreader frame into castings on top of the"stacking posts" and rotating them 90 degrees. Tractor then pulls the chassis away. |
 |
 |
Container is lowered onto lower-deck container. Stacking posts on 48ft. container are inset to permit stacking compatibility with 40ft. boxes |
Loading operation complete, the spreader is raised. |

Norfolk Southern's crane shown here is unusual in that it rides on steel flanged wheels instead of rubber tires. |
