摘要： The present invention relates to a crane, for example in the form of a fast-erecting crane comprising a telescopic and/or luffing tower, having a crane controller for controlling crane movements by means of drive devices, wherein the crane controller has a monitoring device for monitoring stability and limiting crane movements if a load limit is reached. According to the invention, the monitoring device has a wind resistance detection unit for detecting at least one variable wind resistance parameter which influences the wind resistance of the crane, and is designed to change the load limit depending on the detected wind resistance parameter and/or to consider different load limits depending on said wind resistance parameter.

摘要： An emergency-operation valve block includes: a drive port for hydraulically connecting the valve block to an emergency drive of a mobile crane, at least two drive mechanism ports for hydraulically connecting the valve block to one drive mechanism of the mobile crane each, at least two closing valves which are assigned to one of the drive mechanism ports each and designed to selectively open or close a hydraulic connection between the drive port and the drive mechanism port respectively assigned to it, and an actuation valve which is designed to selectively reverse the hydraulic connection between a pressure side and return side of the drive port and corresponding sides of the drive mechanism ports. A mobile crane may include such an emergency-operation valve block.

摘要： A work machine includes a lower traveling body, an upper swing body swingably mounted on the lower traveling body, a work device attached to the upper swing body, a hook attached to the distal end of the work device, an acquisition device configured to acquire information on the conveying destination of a suspended load to be suspended from the hook, and an imaging device attached to the upper swing body and configured to acquire image information related to a situation in an area in front of, behind, and beside the upper swing body. The situation includes the state of the suspended load. The work machine is configured to automatically convey the suspended load to the conveying destination by causing at least one of the lower traveling body, the upper swing body, and the work device to operate.

摘要： A safety system (2) for a working vehicle (4) comprising a working equipment (6), e.g. a crane or a working tool, the safety system (2) comprises a control unit (8), a controller (10), e.g. a remote controller, configured to control said working equipment (6), and a display unit (12). The control unit is configured to:
define a set of three-dimensional safety spaces (14) in relation to the vehicle (4),
present at least one safety space (14) from said set of safety spaces on said display unit (12), wherein said at least one safety space being presented overlaid on an image (18) of at least a part of the working vehicle (4) and working equipment (6),
receive a first input signal (20) comprising space position parameters representing at least one chosen safety space among the presented safety spaces, and to designate each at least one chosen safety space as an active safety space (14A), and to
receive a second input signal (22) comprising a safety space state command either allowing or preventing said working equipment to be moved into said at least one active safety space (14A), and to apply a state command signal (24) to said controller (10) to control said working equipment (6) in dependence of said safety space state command.-

摘要： Aspects of this disclosure relate to a system that uses images of a load handled by a crane as captured by cameras to monitor the load. The images may include different sets of outer perimeters of the load. The system may identify the outer perimeters and then define a safety zone that extends beyond these outer perimeters. In response to identifying an object within the safety zone, the system may execute a remedial action.

摘要： A tower crane includes a tower on which a rotating portion is pivotally mounted and configurable between a service configuration in which the rotating portion can be rotatably driven by a motorized orientation system, and an out of service configuration in which the rotating portion is rotatably released to be able to be oriented in the direction of the wind. A control/command unit activates a monitoring mode in the out of service configuration to detect, depending on variations in the angle of orientation or the angular speed of the rotating portion, if the rotating portion is in one of the following movement states: an autorotation state corresponding to a rotary movement of the rotating portion in a given direction over at least one complete turn; or an oscillation state corresponding to a back and forth movement of the rotating portion about the orientation axis.

摘要： An adaptation method is provided for adapting a load curve of a crane to a configuration of the crane, wherein the configuration of the crane is associated with a plurality of crane parameters among which a selection of at least one preferential parameter may be operated. The adaptation method includes implementing a determination of a preferential load curve from among a plurality of load curves calculated as a function of the selected preferential parameter.

摘要： 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.
