WESTPORT, Conn. - Heavy equipment maker Terex Corp. said Thursday it will cut 170 employees who work at its plant in Cedar Rapids, Iowa, as it moves the equipment manufacturing there to other facilities. The company said the temporary shutdowns and layoffs already made at the plant weren't enough to make up for the steep decline in manufacturing. Engineering, sales and service functions for materials processing equipment now made at the plant will be kept there for the foreseeable future. About 50 jobs will remain in Cedar Rapids. The asphalt pavers, mobile crushing and screening equipment made at the plant will now be made at existing facilities in Durand, Mich., Oklahoma City, and other North American plants.
