Container Weighing - Straddle Carrier

The customer, a container terminal, wanted to weigh all containers while the containers were transported around the port. It was important that the weighing could be done without changing or disturbing the existing workflow. It was also important that the straddle carriers could perform the weighing of the containers while driving around the terminal both over potholes and in curves.

At the same time, the result was transmitted wirelessly to the customer's server, where the weight of the container was naturally stored for later use. The client also wanted the driver of each straddle carrier to instantly see on a screen, if the weight of a container was unevenly distributed between the four corners of the container.

The above picture shows a straddle carrier, a Kalmar ESC 350, while it is weighing a test module that TEKFA built, where the weight was unevenly distributed.

The project was extremely successful and today almost all straddle carriers at the terminal is equipped with TEKFA's load cells, corner weight display in the driver's cabin, wireless transmission to server and communication to N4 Navis (terminal ERP system).

For Tekfa’s customer this project was key to get to know the verified gross mass (VGM) of container ships. This is a point under the SOLAS convention (the international convention for the Safety Of Life At Sea) that has been getting much more attention during recent years.

As it turns out, it is the shippers’ responsibility to know the VGM of containers whereas it is the port, that most economically can install and operate the accurate and efficient weighting system delivered by TEKFA.
