Provided is a stacker crane capable of increasing the rising/lowering speed of an elevator platform and capable of avoiding the collision of part of the elevator platform into masts, even if the elevator platform is inclined. The stacker crane (1) has the elevator platform (20) arranged between a pair of front/rear masts (3) provided in the perpendicular direction, said elevator platform (20) comprising a horizontal frame (21) having a transfer device (F) mounted thereto and vertical frames (22) installed vertically along the masts (3) from both front/rear ends of the horizontal frame (21). The elevator platform (20) rises and lowers in a state in which the vertical frames (22) are suspended. Each of the vertical frames (22) comprises a pair of first guide rollers (30) sandwiching the masts (3) in the left-right direction and coupled in a state so as to be rotatable relative to the horizontal frame (21), using the left-right direction as the axis therefor. |
