Crew was instructed to remove 2 end bolts on a newly installed launder to move a piece of 2 inch angle iron. As the employee removed the bolts the launder swung down to the floor striking the coworker. The crew did not recognize that none of the bolts in the middle section of the launder had been installed. Only two bolts at each end of the launder had been installed.
