LASSTEC prevents the accidental lifting of trailers

The now available LASSTEC Container Load Sensing and Accident Prevention System is able to detect this potential accident situation and it can either alert the crane operator of the danger or interact directly with the crane control system to immediately stop the hoist mechanism. At the same time during the lift, the LASSTEC system also accurately weighs the container and determines any load eccentricity.

Trailer lifting detection which is achieved by a software extension within the LASSTEC control unit, requires no additional hardware to the standard patented twistlock load sensors.

The LASSTEC system continuously monitors and compares the load sensors on all twistlocks while the container is being lifted off the trailer or railcar. If one or more sensors detect a continuous weight increase after the container is initially lifted, the control unit immediately sends an alarm signal. At constant hoist speed, this is accomplished within a maximum 1 m of lifting height – quick enough to prevent major damage.
