The present invention provides an automatic container loading and unloading apparatus and method. The apparatus comprises: a data acquisition module, used for scanning a container truck panel to obtain laser point cloud data; a data preprocessing module, used for segmenting a laser point cloud on a surface of the container truck panel from the laser point cloud data; a key point extraction module, used for performing edge extraction on the laser point cloud on the surface of the container truck panel to obtain discrete points on edges of the keel of the container truck panel; and a straight line fitting module, used for performing random sample consensus straight line fitting on the discrete points on the edges of the keel of the container truck panel to obtain spatial straight lines of the edges of the keel of the truck panel. The automatic container loading and unloading apparatus and method provided by the present invention using spatial straight lines on the edges of the keel of the container truck panel for computing processing, thereby achieving stronger robustness and higher accuracy, so that a container is loaded onto the container truck panel with higher precision and lower calculation amount.

The invention relates to a method for recognising a setup state of a crane in which a crane setup state input manually into the crane controller is compared with the actual current setup state, comprising the steps of determining the target position of at least one target crane element installed on the crane on the basis of a crane setup state stored in the crane controller and at least one crane sensor value, transmitting the one or more pieces of target position data to a mobile flying device, moving the flying device into a region in the immediate vicinity of the target position of the target crane element and detecting and identifying a current crane element located there using a detection means, and identifying the current crane element detected in the detection region and establishing whether the detected crane element corresponds to the target crane element.

There is provided a crane including: a telescopic boom having an inner boom element and an outer boom element; a telescoping actuator that displaces the inner boom element or the outer boom element in the telescoping direction; a first coupling member that releasably couples the telescoping actuator to one of the boom elements; a second coupling member that releasably couples the pair of boom elements to each other; an electric drive source provided at the telescoping actuator; a first coupling mechanism that displaces the first coupling member or the second coupling member on the basis of motive power of the electric drive source, thereby switching a coupled state and a non-coupled state of the members that are releasably coupled by one of the coupling members; and a position information detection device that detects information relating to the position of one of the coupling members on the basis of output from the electric drive source.

Disclosed is an automatic hoisting and transporting method for a tower crane, the method including: building a three-dimensional grid model for a construction site, and generating a grid node set; generating an obstacle node set and a feasible area node set; obtaining coordinates of an initial node and an end node; planning a hoisting and transporting path from the initial node to the end node, and generating corresponding operating parameters; controlling the tower crane to transport an object according to the operating parameters, and calculating a swing range of the hoisted and transported object and a swing arm at a current position; determining whether a collision may occur; and predicting whether the tower crane may be overturned. The method realizes automatic hoisting and transporting of the tower crane. The object does not collide with an obstacle during hoisting and transporting, thereby ensuring safe operation of the tower crane.

A crane hook block includes a frame, at least one pulley rotatably connected to the frame, a load hook connected to the frame, at least one sensor arranged on the crane hook block and designed to detect at least one ambient parameter and/or at least one status parameter of the crane hook block, and an interface connected to the at least one sensor and designed to transmit the data received from the at least one sensor.

The technology disclosed relates a lumber grabber for grasping timber. The lumber grabber can achieve grasping large packages of lumber of various work lengths. In one configuration, the lumber grabber includes moveable forks for grasping lumber movably supported by a frame, affixable to a crane. Forks positioned at ends of the frame and arranged to open and close relative to one other under power by a source of motive force; thereby enabling grasping and ungrasping of packages of lumber under programmed control of a programmable controller executing stored instructions.
