A luffer or luffing crane is often seen in urban areas where site areas are tight. A luffer crane can be determined by the angled jib. The jib is able to move up and down at different angles in order to place the hook where it needs to go. The advantage of a luffing crane is that it can work in tight spaces (or adjacent to other tower cranes) without as much concern for getting hooked on items or having the boom be in conflict with something. The crane can also have increased capacity due to the angle of lifting.
