The LaseUCD - Unremoved Cone Detection application is a three-dimensional laser measurement system that detects whether container locks (twistlocks) are still connected to the container at the beginning of the pickup process by RMG or RTG cranes.
In case of detection of an unremoved twistlock, the application software sends an alarm signal to the PLC to stop the crane lifting movement. The system is specially designed for use in automated and remote-controlled container warehouses and prevents costly damage as well as fatal accidents.

The Measuring System
The measuring system consists of two 2D laser scanners installed on the crossbeam of a crane system at the height of approx. five meters above the truck tracks. Both 2D laser scanners form a common, overlapping horizontal scanning plane in the direction of the truck lane. When a container is picked up from the truck chassis by the crane, it passes the scanning plane in which the container profile is scanned.
The scan data is processed in the LaseUCD application software, from which a 3D point cloud of the container is generated. As soon as an obstacle protrudes below the container, this is an indicator that at least one locking cone is still present or has been forgotten to be removed. In this case, the application software sends an alarm signal to the crane PLC to immediately stop the crane lifting movement.

The LaseUCD system is specially designed for RMG and RTG cranes to increase safety and also to prevent damage to containers and the crane equipment. In addition, the system also detects open doors of containers during the same measurement process.
