Abstract
The present invention addresses the problem of providing a crane capable of detecting a suspension location of a payload, in order to enable accurate positioning of a hook at the suspension location of the payload. This crane comprises: a freely derricking boom provided to a swivel; and a sub-hook block and a sub-hook suspendedly provided from the boom. The crane also comprises: a boom camera capable of imaging a payload that is to be carried by the crane; hook cameras capable of imaging the payload from different viewpoints than the boom camera; and a control device for controlling the crane. The control device acquires images obtained by imaging the payload with the boom camera and the hook cameras, runs image processing on the images, and calculates a suspension location of the payload.
