Gantry Collision Prevention
The LaseGCP-3D - Gantry Collision Prevention measurement system is a driver assistance system that helps crane operators of Harbour Cranes, RTG, RMG, STS or Jib Harbour cranes to avoid collisions and thus increase crane availability.

The system can be used with two or four multilayer laser scanners mounted on the upright gantries. Depending on the number and mounting location, one direction of travel or two directions of travel can be monitored. The generated 3D monitoring areas are generated as a virtual monitoring area in front of the cranes drives in the respective direction of travel.

The measurement system

The laser measurement system consists of two or four multilayer laser scanners mounted on the upright chassis beams at the height of approx. 6m - 7m. The scan planes are formed in up to 64 vertical individual scan planes.
This allows monitoring not only at a single specified height but seamlessly from ground level to a height beyond the installation location of the multilayer laser scanner. The measurement data from the laser scanner is sent to the LASE application software, which evaluates the data and detects emerging hazardous situations in time. Dynamic monitoring fields are generated in the control system, which changes or adapt their extension analogously to the crane speed.

This means that the 3D monitoring areas are small at low speeds and increase in size as the crane speed increases. The fields cover the width of the respective trolley (including stairs that may be located on the side of the crane). From this, the system derives three detection areas, the largest/outermost of which is used to create candidates, making it the so-called "candidate field". These candidates are objects that have a certain size and lifetime and should be protected as soon as they occur within the warning or alarm field.

This prevents false alarms caused by randomly occurring objects, such as snowfall or birds. If an object is within the smaller "warning field", the system reacts and sends a warning to the crane operator, who starts to reduce the speed of the gantry crane. In the event the nearest field ("alarm field") is violated, an emergency stop is automatically triggered.
