Abstract
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
