On July 11, 2019, our after-sales service department received customer feedback. There was a failure of the prestressed jack in the Guangming section of Shenzhen. It was suspected that the displacement sensor KPM model was damaged. Our Shenzhen technicians immediately went to the site for treatment, half an hour. The new KPM model displacement sensor was replaced and the customer's site was restored to normal use.
At present, the state requires the use of prestressed jack systems for construction of road and bridge construction units to ensure long-term and reliable project quality. Our company is also paying close attention to this business.
