Provided are an obstacle sensing system and an obstacle sensing method whereby precision when determining the presence/absence of an obstacle can be enhanced. In sensing of an obstacle by a configuration in which laser light is radiated from a transmission partmounted to a moving body while the irradiation angle θn is varied, and reflected light of the laser light is received by a reception part, a sensing region S is set in advance in a region on the periphery of a reflection position Pn from which the laser light is reflected when there is no obstacle, and a determination mechanismdetermines whether an obstacle is present or absent in accordance with the reflected light reflected inside the sensing region S.

Provided is a quay crane which includes a seismic isolation device formed from laminated rubber, and which is capable of withstanding a large-scale earthquake. Particularly, provided is a quay crane including a seismic isolation device with a slide length of 1000 mm or over. In a quay crane including a seismic isolation device, the seismic isolation device includes: laminated rubber formed by laminating a steel plate and a rubber material; and an auxiliary support mechanism. The auxiliary support mechanism includes: a supporting body fixed to one of a top plate side and a bottom plate side of the seismic isolation device; and a contacting plate fixed to the other thereof. The supporting body and the contacting plate constituting the auxiliary support mechanism come into contact with each other at least in the event of an earthquake, and the auxiliary support mechanism supports a weight of the quay crane.

Provided is a power supply system including a crane and a power supply truck. In the power supply system, a linkage mechanism efficiently transmits a force in a travel direction x to the power supply truck, while not transmitting any force in a transverse direction y or a twisting direction, and has a highly durable configuration. In a power supply systemfor a crane in which a cranefor loading and unloading a container for marine transportation is linked to a power supply truckfor supplying power while following the crane, with a linkage mechanism, the linkage mechanismincludes a receiving memberdisposed on the power supply truck, and a pushing memberdisposed on the crane. The power supply systemincludes the linkage mechanismconfigured in a manner that, when the cranemoves in a travel direction x, the pushing membercomes into contact with the receiving member, to transmit a force of the cranemoving in the travel direction x to the power supply truck, and when the cranemoves in a transverse direction y intersecting the travel direction x, the receiving memberdoes not disturb move of the pushing memberand a force of the cranemoving in the transverse direction y is not transmitted to the power supply truck
