Industry: 3531—Construction Machinery and Equipment
Establishments primarily engaged in manufacturing heavy machinery and equipment of a type used primarily by the construction industries, such as bulldozers; concrete mixers; cranes, except industrial plant overhead and truck-type cranes; dredging machinery; pavers; and power shovels. Also included in this industry are establishments primarily engaged in manufacturing forestry equipment and certain specialized equipment, not elsewhere classified, similar to that used by the construction industries, such as elevating platforms, ship cranes and capstans, aerial work platforms, and automobile wrecker hoists. Establishments primarily engaged in manufacturing mining equipment are classified in Industry 3532; those manufacturing well-drilling machinery are classified in Industry 3533; those manufacturing industrial plant overhead traveling cranes are classified in Industry 3536; and those manufacturing industrial truck-type cranes are classified in Industry 3537.
