Abstract: The present disclosure presents systems and methods for assisting a crane operator. An imaging system automatically images each building material object contained within a shakeout field on a construction site and processes the images to determine each object's identifying indicium and its geometric properties. These values are compared with a construction site database to ensure that all necessary building materials are present. A positioning device tracks, in real time, the location of the imaging system, the location of structural members within the shakeout field, and/or other important features of the job site, such as obstacles that the crane operator will need to avoid while lifting a structural member from its initial location to its destination location. Real-time images of the construction site, including indications of the next building material object to be hoisted and/or a path between the object's initial and final locations, can be generated to guarantee that the crane operator hoists the expected object to the expected location.

Abstract: The disclosure relates to a method for determining the number of rope reevings of a pulley block with a top block and a bottom block, wherein the rope path of at least one rope line of the pulley block, which is covered during a time window, is detected and compared with at least one rope path of a further rope line covered within the time window and/or with the height difference between top block and bottom block changed within the time window, in order to determine the number of rope reevings of the pulley block.

Abstract: A tag reader acquires identification data and data of a reception intensity indicative of an intensity of a reception signal from a weight tag mounted on each weight, and a data processing device acquires the identification data and the data of a reception intensity of each weight tag from the tag reader, discriminates the identification data corresponding to each weight tag into attached weight data indicating that a reception intensity corresponding to the identification data exceeds a reference intensity set in advance and other non-attached weight data, and determines an attachment state of the weight to the main body portion based on the attached weight data.

Abstract: A lifting machinery includes a lower reeve block and an upper reeve block, the lower reeve block hanging by a lifting rope connected to a lifting winch, and a reversible connection mechanical system to be reversibly configurable between two reeving configurations including a connected configuration and a disconnected configuration. The reversible connection mechanical system includes a locking element, a locking complementary element and an elastic return member urging the locking element to engage with the locking complementary element. The lifting machinery further includes a control/command unit configured to pilot the lifting winch and a sensor configured to measure a force on a strand of the lifting rope. The control/command unit is configured to pilot the lifting winch in a connection phase and in a disconnection phase according to the measurement data of the force on the strand of the lifting rope.

Abstract: The present invention provides a remote control terminal which achieves both easy visibility and easy control by indicating the movement direction and the movement speed of a work device as a directed segment according to the operation direction and the operation amount of an operation tool. The present invention provides a remote control terminal which remotely controls a crane device of a crane, the remote control terminal being provided with: a terminal-side communication unit; a suspended load movement operation tool; a terminal-side display device; and a terminal-side control device. The terminal-side control device calculates a vector which represents the movement direction and the movement speed of the crane device according to the operation direction and the operation amount of the suspended load movement operation tool, and the terminal-side control device displays an image in which the directed segment representing the vector is superimposed on the image captured by the camera.

Abstract: One variation of a method for monitoring lift events at a construction site includes: deriving a lifting profile from a first timeseries of load values, output by a load sensor coupled to a crane hook, during a first time period; deriving an oscillation characteristic from a first timeseries of motion values, output by a motion sensor coupled to the crane hook, during the first time period; identifying a type of an object carried by the crane hook during the first time period based on the lifting profile and the oscillation characteristic; selecting a load handling specification for the object based on the type of the object; accessing a second timeseries of motion values output by the motion sensor during a second time period; and, in response to the second timeseries of motion values deviating from the load handling specification, activating an object motion alarm for the object.

Abstract: Provided is a crane and a control method capable of preventing an irregular winding from being caused, without significant deterioration in work efficiency. The crane includes an allowable deceleration rate derivation unit and a winch control unit. The allowable deceleration rate derivation unit derives an allowable deceleration rate representing an allowable value of the deceleration rate of the winding of a suspension rope, from a measured load that is a suspension load measured by a load measurement device. The allowable deceleration rate derivation unit derives the allowable deceleration rate that is decreased with a decrease in the measured load. The winch control unit makes the winding of the suspension rope by a winch device decelerated at a deceleration rate limited within a range equal to or less than the allowable deceleration rate.
