You'll need the remote mines; shoot them at the containers hanging from the roof, then destroy them when he walks under them. They need to land right on him to do any damage. Shoot one at a time. One you get your mine on a container, hold you aim on that container and shoot a second time when he is underneath to get the container to fall on him.
