New SOLAS Compliant Container Weighing System

 

The company said it has been supplying container weighing systems for around five years with more than 40 system sold to date, and have utilized this experience to design a flexible modular system that can be easily and quickly retrofitted onto straddle carriers, container cranes and telehandlers.

 

The new system verifies the container weight in real-time to an accuracy of 1 percent of rated load, although higher accuracies can be achieved with on-site calibration and by utilizing the in-built linearization facility. The standard package is a complete stand-alone system that comprises of four load measuring pins that replace existing load bearing pins on the spreader block, an interface module and a ruggedized 8” tablet. Pre-wired cable assemblies are supplied for system connection, which allows installation to be carried out by untrained personnel as no wiring is required. This also reduces installation time and consequently equipment downtime, as well as facilitates fast and simple replacement of cables in the event of any becoming damaged.

 

The ruggedized tablet displays the load on each twistlock and the percentage of the overall weight it is carrying. This allows for the detection of possible damage to twistlocks due to overloading or unequal weight distribution during container engagement and lifting. Also displayed is the combined weight on all four twistlocks. There is a tare function and the facility to enter container numbers and generate reports. A calibration button on the main screen takes you to a new display screen that enables on-site calibration for optimal accuracy. The tablet is rated to IP67 and drop tested to 1.2m, making it suitable for harsh port environments. 

 

Because every port is different the system can be tailored to meet the specific needs of each individual port. In addition to the standard package a system is available that can be fully integrated into the port Terminal Operating System (TOS) that offers flexibility in terms of data output and data provision. Other types of load cell systems are also available, including annular load cells that are placed around the twistlock assembly or arrangements that utilize the twistlock by turning it into a load measurement device in its own right. Wireless options are also available.

 

Steve Sargeant, Managing Director said, “We have over 30 years’ experience in supplying custom designed engineering solutions, so our container weighing system is just another variant of the hundreds of weighing systems we have supplied over the years. The strain gauge technology that we use is a tried and tested method of load measurement that has been proven to provide highly accurate data for many years in even the most hostile of environments. We have designed exceptional functionality into this system that significantly reduces costs by de-skilling the installation process, while at the same time speeding up the operation to keep equipment downtime to an absolute minimum. We also believe it is an extremely economical solution, with the standard package selling for under £5,000 (€6,200)”.
