To provide a horizontal pulling detection device and a crane capable of preventing the breakage of a boom or a jib due to horizontal pulling movement in advance.SOLUTION: A horizontal pulling detection device 1A is mounted on a crane including a boom provided on a revolving superstructure, a jib provided on a tip end of the boom, and a hook connected with a wire rope that is wound up by a winch. The horizontal pulling detection device detects the horizontal pulling movement of a hoisted cargo hooked on the hook. The horizontal pulling detection device 1A includes a detection unit 41 for detecting pulling force that pulls the jib or the boon sideward, a determination unit 42 for determining that the hoisted cargo is pulled horizontally when the pulling force detected by the detection unit 41 exceeds an allowable value, and a notification unit 50 for providing a notification of the horizontal pulling movement of the hoisted cargo when the determination unit 42 determines the horizontal pulling movement.SELECTED DRAWING: Figure 4
