The system is based on one multilayer laser scanner installed in the middle of the gantry beside the truck lane. The application software connects the sensor to a LASE Control Unit (LCU). Observing the area within the truck lane makes it possible to cover all the abovementioned functions.
LaseTLP - Truck Lifting Prevention
During the lifting of the container, the measurement system tracks the container and the structure of the chassis. When the chassis and container go upwards, the measurement system detects a lifting of the chassis and sends an alarm signal to the crane PLC.
LaseCP - Cabin Position
During the container drop process to the chassis, the measurement system checks whether the truck’s cabin is outside the operation area of the spreader resp. the container.
LaseTMD - Truck Movement Detection
During the loading and unloading process, the measurement system detects when the truck is moving.
LaseESD – Empty Space Detection
Before and during dropping a container, the system measures/detects whether the space on the chassis is empty.
LaseASTO - Area Surveillance Truck Operation
During the chassis loading process, the measurement system observes whether there are people around the truck to raise an alarm when this is the case. Hoist motion will then be stopped.
