Anupama, a Gujarat-based company, won the contract and bought the crane for Rs 17.75 crore.
However, during the load testing in 2018, it was found that the carbon bristles were blown out and the insulators were damaged. The Committee of Experts noted that the shortcomings were still not rectified. On July 20 this year, load testing of 36 tonnes was carried out. The committee of experts concluded that on August 1, a load of 70 tonnes went into testing without rectifying the defects from time to time.
