A safety load hook with a lower part defining a curved hook mouth with a hook opening of a predefined nominal width. An upper part is attached to the lower part and is pivotable into an open position for insertion or removal of a load, and into a closed position blocking insertion of a load or removal of a load. A marking is on each of the end regions of the upper part and lower part which face one another in the closed state. When closed, and when a size of the hook opening corresponds to the nominal width, the lower part marking is offset from the upper part marking. The offset distance is chosen such that when there is a predefined maximum widening of the hook mouth in relation to the predefined nominal width thereof, both markings are located directly side by side in the closed state.

The arm with two or more hooks 1 comprises: a supporting beam 1) designed to be connected to an operating arm 20 of a telehandler 2 or another self-propelled operating machine and a plurality of hooks 11, 12, 13, distributed along the beam 10, each designed for supporting a respective load. One or more hooks 11, 12, 13 are connected to a load sensor 31, 32, 33.

One variation for a system for tracking lifting events at a construction site includes: a chassis configured to couple to a crane block of a crane at a construction site. The system further includes a first idler assembly including a first cable idler, a first idler arm, and a first position sensor coupled to the first idler arm. The first idler arm supports the first cable idler on a first side of the chassis and biases the first cable idler inwardly toward a first cable loop coupled to the crane block. Additionally, the system includes a controller configured to, during a lift event: read a first position value from the first position sensor; predict a weight of the load carried by the crane block based on the first position value; and generate a lift event record containing the weight of the load carried by the crane block.

Various embodiments relate to a demounting aid for demounting a hoisting fitting from a workpiece, such as from an aircraft structural component, comprising a first connector and a second connector, a force measurement device for measuring the force applied between the first connector and the second connector, a display for displaying an information corresponding to the respective force applied between the first connector and the second connector and at least one elastic member which allows a relative movement of the first connector to the second connector when an increasing force is applied to the first connector and the second connector.

A person lift system includes a lift unit, a sling bar that is coupled to the lift unit, where the sling bar includes a plurality of attachment points each having coupling sensors and an electronic control unit that is communicatively coupled to the coupling sensors. The person lift system also includes a lifting accessory having a plurality of lifting points that are adapted to be selectively coupled to the plurality of attachment points of the sling bar. The electronic control unit comprises a processor and a computer readable and executable instruction set which, when executed by the processor detects with the coupling sensors whether the lifting accessory is installed in a proper manner and projects an indication when the lifting accessory is installed in the proper manner.

The crane device includes: a camera provided on a hook; a camera control unit which controls an image-capturing operation of the camera on the basis of control information for operating a 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 a 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.

A monitoring detection device and crane for displaying real-time hook bias angle, characterized in that a fixed pulley assembly a1 of a crane is hung on a lifting lug b2 of a crane boom b1 by a shackle a5 through a connector a3. the connector a3 is connected to the fixed pulley assembly a1 through a articulated shaft a2 which is arranged in a direction perpendicular to the axis of a fixed pulley; a platform surface perpendicular to a pulley block force application line or a line parallel to the pulley block force application line is arranged on the connector to be used to. Beneficial effects: the real-time hook bias angle can be accurately displayed when the crane is lifting: Beneficial effects: the real-time hook bias angle can be accurately displayed when the crane is lifting.
