    摘要： The present invention relates to the technical field of engineering machines, in particular to a gantry crane (1) lightning protection device, a machine and a use method thereof. The gantry crane (1) lightning protection device includes:a rotatable rod (2) structure, including a rotatable rod (2), wherein the rotatable rod (2) is fitted inside an insulating sleeve (13) of a gantry crane (1); an umbrella net structure (11), including a guide sleeve (3) threadedly and rotatably connected with the rotatable rod (2) in a sleeving manner, wherein the guide sleeve (3) is arranged on an outer circumference of the rotatable rod (2), conductive longitudinal rods (4) are arranged at intervals on the guide sleeve (3), and conductive cross-rings are arranged at intervals and around the conductive longitudinal rods (4);the radii of the conductive cross-rings are different from each other so that the heights of positions are also different from each other when the umbrella net structure (11) is unfolded;and a conductive structure, including a conductive wire (14) and a grounding carbon rod (15), wherein one end of the conductive wire (14) is fixedly connected with the rotatable rod (2), the other end thereof is connected with the grounding carbon rod (15), and in a lightning protection state, the conductive longitudinal rods (4) extend out of the insulating sleeve (13), the conductive cross-rings unfold along the circumferential direction of the conductive longitudinal rods (4) into an umbrella shape, and the conductive cross-rings and the conductive longitudinal rods (4) together form an umbrella-shaped structure, so that the gantry crane (1) is shielded from lightning, wherein lightning is transmitted to the conductive wire (14) by the rotatable rod (2), and finally transmitted to the ground by the conductive wire (14) via the grounding carbon rod (15). The invention solves the problem that the gantry crane (1) can not be covered by the lightning rod, and as a result, the protection effect is affected.

    摘要： A guide display unit for a crane, wherein a data processing unit: calculates a measurement area corresponding to the measurement area of a camera; the measurement area from the viewpoint of the camera and generates a first image; performs mosaic-processing on the image captured by the camera according to the particle size of the three-dimensional map and generates a second image; performs registration processing on the first image and the second image and calculates the amount of deviation between the first image and the second image; corrects the position of a guide frame figure with respect to the image of a suspended load and a feature on the basis of the calculated amount of deviation; and overlays the guide frame figure on the images of the suspended load and the feature and displays the result on the data display unit.

    摘要： Provided is a crane device which is capable of performing highly accurate installation work without being influenced by a shape of baggage and an installation condition of the baggage.
    The crane device, which actuates a carrying element including a boom and a hook suspended from the boom and carries the baggage to a carrying destination, includes: a camera provided on the hook; a camera control unit which controls an image-capturing operation of the camera on the basis of control information for operating the carrying element; and an image processing unit which processes a captured image that has been captured with the camera. The camera captures an image of the carrying destination of the baggage. The image processing unit takes, as a reference area, an arbitrary area in the image captured with the camera, generates a correction image obtained by projecting the captured image onto a plane that is parallel to the reference area and is perpendicular to an arbitrary direction with the baggage used as a viewpoint, calculates a current position of the baggage in the correction image, and displays the current position in a visually recognizable mode.
