摘要
A crane for loading and unloading a cargo includes a trolley assembly (200). The trolley assembly (200) includes a first trolley (210) movable in a longitudinal direction along a boom of the crane; a second trolley (220) movable in a lateral direction on the first trolley (210); a hoist (250) provided on the second trolley (220); a spreader (260) movable in a vertical direction by the hoist (250); a light emitting unit (270) provided on the spreader (260); and a smart camera (280) for capturing an image of the light emitting unit (270) to measure a movement of the spreader (260). A movement of the hoist (250) is controlled by a location control unit (290) based on the measured movement of the spreader (260).
