Gantry Collision Prevention
The LaseGCP-2D - Gantry Collision Prevention measurement system is a driver assistance system that helps crane operators avoid collisions and thus increase crane availability. The system can be used with two or four 2D laser scanners mounted on the upright gantries close to the drives. Depending on the number and mounting location, one direction of travel or two directions of travel can be monitored. The generated scan planes are generated horizontally across the floor in the respective direction of travel.

The measurement system

The laser measurement system consists of two or four 2D laser scanners of the LASE 2000D series, which are mounted on the upright chassis beams at the height of approx. 1.0 - 1.5 m. The scanning planes are projected parallel to the ground. The measurement data from the laser scanner is sent to the LASE application software, which evaluates the data and detects any hazardous situations that arise in good 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 scan fields have a small extension at low speeds and increase as the crane speed increases. The fields cover the width of the gantry area (including stairs that may be 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.
