摘要： A method is provided for controlling an operation of a mobile crane, the operation comprising a user input, the user input comprising a command to change a configuration of the mobile crane. The method comprises the steps of: determining a current tipping moment of the mobile crane, the tipping moment comprising a moment about a tipping line of the mobile crane; predicting an effect of the user input on the tipping moment of the mobile crane; and if the predicted effect of the user input is to increase the tipping moment of the mobile crane past a predetermined amount, altering a response to the user input. A system for controlling an operation of a mobile crane, and a user display system for a mobile crane are also provided.

摘要： A vehicle crane having a luffable main jib and an additional jib system arranged on a free end section of the main jib and comprising a first additional jib part and a second additional jib part. To further reduce the weight of the additional jib system and the vehicle crane fitted therewith, and to permit an overall more economical mode of production, the first additional jib part has a rectangular cross-section having four longitudinal chords connected together via transverse struts or/and diagonal struts and the second additional jib part has a triangular cross-section having three longitudinal chords connected together via transverse struts, wherein the two additional jib parts are coupled, or can be coupled, together via a cross-section change adapter.

摘要： A crane vehicle achieves safe movement by reliably detecting an obstacle in a region which is a blind spot from the opposite side of the driver seat across a boom. The crane vehicle includes an obstacle sensor which is a transmission/reception antenna that transmits a detection wave and receives the detection wave reflected from the obstacle. A signal corresponding to the reflected wave received by the obstacle sensor is amplified and input to a controller, which calculates the position and the size of the obstacle on the basis of the signal. The controller generates an obstacle display image and displays the image on a display, the obstacle display image including a vehicle object that represents a crane vehicle and an obstacle object which is an object corresponding to the calculated size of the obstacle and which is disposed at a position corresponding to the calculated position of the obstacle.

摘要： A crane includes a carrier unit having a chassis, tires connected to the chassis, a carrier deck and outriggers. A superstructure is mounted on the carrier unit, the superstructure includes a telescoping boom. A slope sensor is operably connected to the carrier unit and configured to detect a pitch and/or a roll of the carrier unit during a lift operation. The crane further includes a system for monitoring a load lifted by the telescoping boom. The system is configured to determine the current load lifted by the telescoping boom, receive pitch and/or roll information of the carrier unit from the slope sensor, adjust coordinates of the crane in a coordinate system based on the pitch and/or roll information, determine a transformed operating radius using the adjusted coordinates; and compare the load lifted to a rated capacity at the transformed operating radius.

摘要： A vehicle crane, such as a mobile crane or a crawler crane, includes a main boom, a main boom extension, and an adapter that is located between the main boom and the main boom extension and which has a first connection plane and a second connection plane. The adapter is configured to be movable such that the first connection plane can be moved relative to the second connection plane, where the adapter is designed in the manner of a double lever in order to provide a vehicle crane that has improved load-bearing capacity and simplified set-up.

摘要： In a method for determining a load that is lifted or to be lifted by a hydraulic lifting device, for the determining the load lifted or to be lifted, in a reference phase, the lifting device is moved into a reference position in a first loading state of the lifting device. A first detection of the forces currently acting on the lifting device and the current geometry of the lifting device occurs in the reference position. In a measurement phase, the lifting device is moved into a measurement position in a second loading state, and a second detection of the forces currently acting on the lifting device and the current geometry of the lifting device occurs in the measurement position. In a comparison phase, the lifted load is characterized by a comparison of the respective detected forces currently acting on the lifting device and the respective detected current geometry of the lifting device.

摘要： Provided is a work vehicle with which crane work maintenance can be carried out efficiently. Device information relating to a work device that performs prescribed work is detected, and it is determined whether or not the device information indicates a management operation state in which a management operation, which is carried out such that an operation corresponding to the prescribed work is performed, is being carried out. When the management operation state is determined to be in effect, engine stopping is restricted even if an engine stopping condition is net.

摘要： The present disclosure discloses an operating method of a wind power jib of a crane and a crane, and relates to the field of engineering machinery. The method includes the following steps: rotatably connecting a main boom and a wind power jib; overturning the wind power jib to a first preset position by using a traction means of the crane; contacting a cushioning member with the wind power jib provided at the first preset position; further drawing the wind power jib to overturn to a second preset position; releasing the traction means, such that the wind power jib overturns automatically under the effect of self gravity and a cushioning member until the wind power jib is overturned in position.
