A crane is a machine that lifts, lowers, and moves loads using a hoist and a boom, jib, bridge, or similar structure. Crane lighting must support safe visibility around the load, working area, access routes, and machine structure without causing glare. Different crane types include mobile, tower, crawler, overhead, and gantry cranes, each with distinct mounting and visibility needs. Suitable lighting helps the operator see the hook, load, boom or jib, outriggers, access points, and people in the operating area. Careful positioning and aiming are important because elevated lamps can otherwise create glare or deep shadows.
