The LZRWL-IP-RED-200MW-1227 is a high-visibility outdoor-rated crane warning laser designed to warn people of ongoing crane operations. The crane warning laser comes equipped with a special optic located on the front that allows it to project a line of light instead of only a single dot. It is designed to be mounted on the arm of a crane and projects a 120-, 60- or 30-degree angle line onto the floor where the crane is operating.
