hook and spreader bar is limited to areas where

equipment such as overhead or mobile cranes can be

utilized (figs 5-58, 5-59, and 5-60). Materials may be

loaded or unloaded directly from the racks, open

railcars, or trucks. Each rack is a separate unit that will

nest securely and safely on top of the rack beneath.

Care should be exercised when loading the nesting-type

racks to ensure that the material is "weight centered"

lengthwise in the racks. This will improve the safety

factor and reduce the swaying of the load when hoisted.
