China's leading construction enterprise Xuzhou Construction Machinery Group Co Ltd announced it now boasts full proprietary intellectual property rights for all key components of its all-terrain cranes, injecting fresh impetus into China's high-quality development.

The remarks were made on Sunday by Shan Zenghai, a deputy to the National People's Congress and chief engineer at the group, at the delegates' passage interviews during the ongoing two sessions.

According to Shan, the company's all-terrain cranes have undergone technological upgrades and now reach a global leading level. The domestic content ratio of the entire machine has increased from 71 percent to 100 percent, with all key components now made in China.

"Such cranes are considered to be the most technologically challenged products in the construction machinery industry, with the greatest research and development difficulty awaiting to be overcome. It took more than 200 technical experts and 100 senior technicians to work for a year to overcome all the obstacles and achieve the capability of self-innovative product design and manufacturing," Shan said.

Shan said that going forward, the company will make efforts to develop into a world-class enterprise and improve the international competitiveness of its products.
