A guide information display device is equipped with a data processing unit which: estimates the top surface of a hoisting load, the ground surface, and the top surface of the object, on the basis of a data point group obtained by a laser scanner; generates guide frames representing guide frames that surround the top surface of the hoisting load and the top surface of the object, and also generates height information and height information which represent the elevation of the hoisting load and the object; calculates the distance between the hoisting load and the object on the basis of the estimated top surfaces of the hoisting load and object; and outputs a warning display when the distance is equal to or less than a threshold. The guide information display device is also equipped with a data display unit for displaying guide information obtained by overlapping an image captured by a camera with the guide frames, the height information and the height information, and the warning display which were generated by the data processing unit.

The construction machine carries out at least individual work steps such as the traveling of a construction element in automated manner using digital data from the master construction site computer. A control module that can be positioned at the load suspension means and/or at the construction element to be traveled and that can be configured as a wearable, in particular in the form of gloves having integrated movement control sensors is provided for the fine positioning.

The present disclosure relates to a method for real time monitoring of the current status of a construction site having one or more work machines, wherein a monitoring means installed at least one work machine monitors the environment of the work machine in real time and generates corresponding monitoring data, with the generated monitoring data being transmitted by the monitoring means to at least one processing unit for a real time evaluation of the current construction site status.

The invention relates to a method for operating multiple cranes (1, 2), the movements of which are monitored for imminent collisions by anti-collision devices of the cranes, and to cranes comprising at least one movement device for moving a crane element, a control unit (13) for actuating the movement device, and an anti-collision device (17, 18) for monitoring the crane movements of the crane element for possible collisions with another crane. According to the invention, in the event of an imminent collision between a first crane (1) being operated and a second crane (2) which is not being operated, the first crane is stopped; a remote control connection (21) is established from the first crane to the second crane; the second crane is moved out of the collision region (130), which is interfering with an intended movement of the first crane, by means of control commands, which are provided at the first stopped crane and transmitted to the second crane by the remote control connection; the second crane is stopped after being moved out of the collision region by remote control; and the first crane is started up again so that the first crane can carry out its task.

A hydraulic crane comprising: a rotatable column (7); a crane boom system comprising a first crane boom (11) connected to the column; and an electronic control device for controlling the movement of the column and the crane boom system on the basis of control signals from a manoeuvring unit and a calculation model for boom tip control. The control device is configured to switch from a first control mode into a second control mode when the first crane boom is about to interfere with an obstacle. In the first control mode, the control device controls the crane boom movements in accordance with an ordinary control strategy. In the second control mode, the control device makes the load suspension point (P) of the crane boom system move along the trajectory defined by said control signals while controlling the crane boom movements in accordance with an auxiliary control strategy in which the first crane boom is prevented from interfering with the obstacle.

A method for controlling a crane component of a tower crane in proximity of obstacles at a worksite by defining a forbidden volume is disclosed. In the method a distance from the crane component to an outer surface of the forbidden volume is determined and a computing device limits movement of the crane component based on the distance from the crane component to the outer surface of the forbidden volume to avoid entering the forbidden volume with the crane component while the crane is in operation. The crane component is one or more of a boom and a hook block.

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.

A safety system for a load carrying machine comprising: a controller, a location sensing arrangement in electronic communication with the processor, the location sensing arrangement configured to determine a location parameter of a load, a monitoring arrangement, the controller configured to receive the location parameter and determine a projected area of the load and control the monitoring arrangement to focus on the projected area to monitor the projected area.

Provided is a display apparatus fir traveling cranes which is capable of displaying information about another traveling crane. The display apparatus for traveling cranes is equipped with: an imaging unit 20 which is mounted to the vicinity of the tip of a boom; a display unit 30 which displays an image captured by the imaging unit 20; a crane controller 40 which controls the orientation of a traveling crane; a communication unit 53 for mutually transmitting/receiving information to/from the other traveling crane; and an image controller 50 for displaying the information about the other traveling crane, received from the other traveling crane, in such a manner as to superimpose the information upon the image of the display unit.
