<p>A crane including a cabin (4) provided on the left or right side, a boom (5) raised and lowered around a pair of boom feet (5a,5b) provided on the left and right sides of the base of the boom (5), and a gantry (9) provided behind the boom (5). The boom foot (5b) on the side of the cabin (4) is located in a position determined by the width of the crane and the width of the cabin (4). The center line (B) of the boom (5) is located on the opposite side of the center line (A) of the gantry (9) from the cabin (4) so that the distance between the boom foot (5a) on the opposite side from the cabin (4) and the center line (A) of the gantry (9) is greater than the distance between the boom foot (5b) on the side of the cabin (4) and the center line (A) of the gantry (9). <IMAGE></p> |
