LaseTLP- Truck Lifting Prevention

Sometimes it might occur that truck-trailers are lifted up by the crane hoist when one or more twistlocks are still locked or not completely loosened. In order to prevent such accidents a system is required to detect the lifting of the trailer early enough. The measurement system consists of one or two LASE 2000D laser scanners which are mounted at the gantry of the crane with vertical scan planes aligned towards the truck lane. The scanner(s) track the objects and compare the position of the lifted container and the trailer structure. In case that both objects (container & trailer) move upwards due to one or more locked twistlocks, the system generates an immediate alarm signal to stop the hoist movement before any damage or injury can occur.

Furthermore the system is both very sensitive (reacts fast in case of lifting) and it eliminates false alarms – these benefits make it to a reliable and highly accepted system by the port operators.
