PROBLEM TO BE SOLVED: To provide a level luffing crane which can easily move a cab forward and backward in accordance with the movement of a suspender.SOLUTION: A level luffing crane comprises: a front link 107 tiltably installed on a base 104; a main link 113 which is connected to a distal end of the front link 107 via a shaft 107b, and whose dital end is configured to protrude in conjunction with falling of the front link 107 and to be retracted in conjunction with standing of the front link 107; a suspender 18 suspended from the distal end of the main link 113; a movable frame 123 configured to be slidable on the base in a retracting direction of the main link 113 while supporting a cab 121; and an additional link 124 connecting the main link 113 and the movable frame 123. The movable frame 123 is configured to slide in conjunction with the movement of the main link 113 in the retracting direction.SELECTED DRAWING: Figure 1
