A control unit performs a travel stop process for stopping travel of a travel unit in response to an indicator detection unit detecting a stop notice indicator section and then detecting a stop position indicator section. After the travel of the travel unit is stopped as a result of the travel stop process, the control unit performs a transfer process for causing a transfer unit to transfer an article. The control unit performs, instead of the transfer process, anomaly notification processing for providing a notification of an occurrence of an anomaly to a superordinate control unit, after the travel of the travel unit is stopped by the travel stop process, in response to: (i) a travel distance, from a position at which the indicator detection unit has detected the stop notice indicator section, being smaller than a determination distance smaller than a notice distance, and (ii) the indicator detection unit detecting the stop position indicator section.

A hydraulic crane comprising: —a rotatable column (7); —a crane boom system (10) comprising two or more liftable and lowerable crane booms (11, 13); and —an electronic control device (25), which is configured to prevent an execution of crane boom movements that would make the lifting moment of the crane exceed the maximum allowed lifting moment of the crane, and to continuously establish position information as to the prevailing position of the load suspension point (P) of the crane boom system. When the lifting moment of the crane has reached a limit value at a given level below the maximum allowed lifting moment, the electronic control device is configured to prevent the execution of any combination of crane boom movements that would increase the horizontal distance between the load suspension point and said vertical axis of rotation and at the same time allow the execution of any combination of crane boom movements that keeps said horizontal distance unchanged or reduces said horizontal distance.

An overhead system assists an operator in moving an object when the operator imparts a manual force to the object in a shared workspace characterized by overlapping ranges of motion of the robot and operator. The system includes an articulated serial robot, a cable, sensors, and a control system. One end of the cable connects to a distal end link of the robot. Another end of the cable connects to the object to suspend the object. The sensors measure a cable force and/or angle. The control system regulates operation of the robot by translating vertically and horizontally in response to the cable force and/or angle. The control system limits the position and/or velocity of the end link according to corresponding work space rules, including respective position and velocity limits, such that the system is immune to a single-point failure.

Provided is a guide display device with which it is possible to track a hung load and display guide information. Also provided is a crane including such a guide display device. A guide display device of a crane including a data processing unit that creates a plurality of surfaces using point cloud data, which is acquired by a laser scanner from above a hung load and which includes the hung load, and creates a three-dimensional map according to the plurality of surfaces, the three-dimensional map being created for each prescribed period, wherein the data processing unit is configured to set a reference position at the hung load in the three-dimensional map and also set a current surface present within a prescribed distance from a past reference position as the surface of the hung load, thereby tracking the hung load in the three-dimensional map.

To allow a worker to visually recognize information for assisting transportation of a transport object and the transport object at the same time. A guidance system includes a guidance device and a controller. The guidance device has a display portion. The controller stores information of a target position of a transport object. The controller calculates a detected position which is a current position of the transport object based on a detection result of a detection portion, and further calculates a position deviation which is a deviation of the detected position from a target position. The display portion displays information of the position deviation.
