On November 11, 2022, the dynamic and accurate weighing system of 9 gantry cranes in the west port area of a wharf successfully passed the owner's acceptance. After the statistics of the on-site loading and unloading dynamic and accurate weighing system and the comparison and verification of the actual weighing weighing, In the end, the error of the weite brand dynamic and accurate weighing system reached 0.87%.

On-site loading and unloading of goods

After the system was installed, there just had a cargo ship unloading corn on site at the unloading dock. According to statistics, the gantry cranes accumulatively grabbed 3,490 buckets.

The dynamic weighing is carried out synchronously, and finally the gantry crane dynamically weighs the whole ship with a weight of 46836.91 tons.

Based on the balance relationship between motor power and load moment, the weite brand dynamic and accurate weighing system integrates the transient response of the load sensor to realize accurate measurement statistics and safety protection during the dynamic loading and unloading of cranes, and solve the problem of low efficiency of traditional measurement statistics.

Actual Cargo Weighing

After the corn unloading operation is completed by the cargo ship at the wharf, the corn will be transported to the designated place by the truck, and each bucket of the goods will pass the weighbridge for unloading inspection on site. According to the actual statistics on site, the transport vehicles passed the weighbridge 1,895 times when they left the port, and the weighbridge statically weighed the whole ship's weight in total to 47,250.5 tons. According to calculations, the weighing error of the whole ship's cargo in the dynamic and accurate weighing system of a terminal is 0.87%, which is far lower than the expected dynamic weighing accuracy error of 2%.

The inspection effect meets the expectation and the customer evaluation is satisfactory

The difference between the dynamic precision weighing system &LMI& overload limiter mainly lies in the accuracy and function. The national standard for torque and overload limiters requires that the comprehensive error should not exceed 5%, while the dynamic accurate weighing system can reach within 1%. Accurately calculate the weight of the cargo without affecting the hoisting operation.
