Alternatives
With the increasing versatility of Self Propelled Modular Transporter (SPMT) and modular low loaders, pure ballast tractors are not as common, with most being a heavy duty tractor unit with a removable "Ballast" box fixed in place of the fifth wheel unit. Ultra heavy loads of 200 ton plus generally are only moved short distances and SPMT's are more manuverable. Items commonly moved include: oil rig modules, bridge sections, buildings, sections of ships, industrial machinery.

Famous quotes containing the word alternatives:
“The literal alternatives to [abortion] are suicide, motherhood, and, some would add, madness. Consequently, there is some confusion, discomfort, and cynicism greeting efforts to “find” or “emphasize” or “identify” alternatives to abortion.”
—Connie J. Downey (b. 1934)
“The last alternatives they face
Of face, without the life to save,
Being from all salvation weaned
A stag charged both at heel and head:
Who would come back is turned a fiend
Instructed by the fiery dead.”
—Allen Tate (1899–1979)
“Clearly, society has a tremendous stake in insisting on a woman’s natural fitness for the career of mother: the alternatives are all too expensive.”
—Ann Oakley (b. 1944)
