LASE GmbH’s LaseTLP 2D laser scanners for truck lifting prevention have been installed and are operational on six HHMC RMG cranes at Sun Kwang Newport Container Terminal (SNCT) in Incheon, South Korea.

The laser scanners detect truck liftings, which occur when any twistlock is locked or jammed, before the lifting from a truck has begun.

LASE explained two scanners out of the LASE 2000D-11x series are mounted on the side of the gantry with a vertical scan plane. The mounting position of both laser scanners is in the middle of the crane at a height of approximately 1.5m and facing the truck lane.

Intelligent detection

In the case that a truck is in front and the hoist lifts up the container, the measurement system detects whether the trailer is still connected to the container by any locked or jammed twistlock(s) and stops the operation.

The biggest advantage of LaseTLP is the fast detection of the trailer lift, said LASE. Other methods mostly use horizontal scan planes that look whether the wheels are up in the air or not.

The company stressed that just one connected twistlock makes it possible to lift up the truck cabin to a height of 4m, until the wheels will be lifted up.

It added that LaseTLP is designed to prevent injuries and damage claims.

In Q2 2018 another 14 systems will be installed at SNCT, to bring the total number of LaseTLP systems in use at the terminal to 28.
