LaseMF

MULTI-FUNCTIONAL MEASUREMENT SYSTEM FOR YARD CRANE

LaseMF is a modular, multifunctional laser measurement system based on multilayer laser scanner technology. The MF base system is equipped with the necessary functional modules depending on the application. The listed functions are available individually or in combination. The range of functions, number of scanners, and sensor positioning are configured specifically for each crane based on the selected modules.

The Application

The multilayer laser scanners used monitor the relevant areas of the crane and capture the measurement data required for the specific application. The sensors are connected to a LASE control unit (LCU) and the application software. Based on this setup, LaseMF enables reliable detection, evaluation, and provision of the selected functions.

LaseGCP - Gantry Collision Prevention
The sensors observe the area in front of the gantry and detect whether objects are in the driving path. The system includes crane-to-crane collision prevention.

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.

LaseCPD - Cabine Position Detection
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.

LaseASTO - Area Surveillance Truck Operation*1
While the chassis is being loaded, the detection system monitors the scanner’s detection zone to see if anyone is near the truck, and sounds an alarm if necessary. Hoist motion will then be stopped.

LaseTPS - Truck Positioning System
The measurement system measures the position of the chassis and the container on the chassis. It gives feedback to the truck driver via a digital display about his relative position in the crane’s centre.

LaseESD - Empty Space Detection
Before and during dropping a container, the system
measures/detects whether the space on the chassis is empty.

*1 There is limited ASTO function due to the limited view on the truck/chassis side on the side facing the yard in case a container is on the chassis.
