That¡¯s why Shandong Gold started the search for  domestic made equipment.

    After long time analysis of key elements, such as design, production capacity, performance, quality, price, after-sales service, etc.£¬finally, the company decided the experimental cooperation with Zhejiang Zhigao Machinery Co., Ltd. Since 2015, it has purchased the ZY104M rock drills produced by Zhigao Machinery. After more than a year of tests, because of stable performance and low consumption, and full after-sales service ,the company finally decided to use domestic drill jumbo in the new mines.In March of this year£¬ZEGA UJ21 won the bid and the company signed the contract with Zhejiang Zhigao Machinery Co.,ltd.

    According to the contract,  Shandong Gold Mining Co., Ltd will arrange all staff for training on equipment operation, maintenance and management in July, then on August 2nd, the first UJ21 equipment officially delivered to Shandong Gold Mine Co.,ltd.
