A method for positioning a straddle carrier for containers and a container to be placed behind a container that has already been placed. The straddle carrier is moved by means of travel supports, travel drives, and a controller that interacts with same, and measurement signals from sensors arranged on the straddle carrier are processed by the controller in order to move and position the straddle carrier and the container to be placed.

A measuring device for load sensing in a lifting-cable-based hoist, in particular a crane, having at least one pulley for deflecting the lifting cable of the hoist, a fastening means in the form of a cable loop, at the end of which the pulley is mounted so as to be rotatable about its roller axis, and at least one measuring element for sensing a force applied to the pulley.

Disclosed are a dynamic simulation display method and a system for a working machine structure. The method firstly acquires working condition data such as angle data of a lower arm of a working machine in real time, and then dynamically updates the currently displayed working machine structure according to the working condition data obtained, which enables users to grasp a working condition change, a working state, a relative position and other information of the working machine according to the updated displayed working machine structure intuitively. A burden of information acquisition on the users may be reduced, and using experience of the working machine on the users may be improved.

Provided is a guide display device with which incorrect recognition of a place having small features as a ground surface having no features can be suppressed in generating and updating a three-dimensional map. A data processing unit (70): detects an edge (Eg) of a feature (E) on the basis of a result of subjecting image data captured by a camera (61) to image processing, and recognizes the feature (E) on the basis of the edge (Eg); and accumulates, from a predetermined number of frames from before the time at which the image data was captured, point group data (P) of a nearby range (Ma) of the edge (Eg) of the feature (E) that was recognized as a ground surface (F), and generates, on the basis of the accumulated point group data (P), a three-dimensional map (M) of the feature (E) the edge (Eg) of which has been recognized.
