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.

A crane in which a boom configured to be freely raised and lowered is provided on a slewing platform, and a hook block and a hook suspended from the boom are provided, the crane further comprising:
- a first camera provided at the boom and configured to capture an image of a load as a carrying object that is carried by the crane;
- a second camera provided at the hook block and configured to capture an image of the load from a perspective different from the first camera;
- and
- a control apparatus configured to calculate a lifting position of the load by image processing on the image of the load captured by the first camera and the second camera.
