Patent number: ZL2006 2 0096888.4
Patent application date: May 24, 2006
Patent holder: Wang Huazhong
Announcement date of authorization: June 6, 2007
1998, Wang Huazhong and his brother Wang Hualiang, who resigned from the enterprise, saw the excellent situation that the infrastructure construction in Xiangyang District was in full swing and the demand for construction machinery such as excavators was increasing, and they engaged in the rental and sales business of construction machinery in partnership.
By chance, when chatting with customers, Wang Huazhong heard that the excavator in brick factory consumed too much and the transportation was incoherent. He had a brainwave and came up with the idea of making a hanging excavator. After continuous test and improvement, a new type of cantilever excavator was finally successfully trial-produced. This new machine is very suitable for brick factories, and all major brick factories have ordered it. Wang Huazhong and his brothers are full of hope for the future of mechanical manufacturing. They simply gave up the rental and sales business of construction machinery, registered Xiangyang Zhongliang Construction Machinery Co., Ltd., and concentrated on R&D and production of suspension excavators.
In 2002, the state issued regulations prohibiting the production of bricks by indigenous methods, and the hanging excavator had no place to use, so the company was in trouble. At this moment, Wang Huazhong heard another news when chatting: a friend who was mining said helplessly: "Now the slag in the underground is completely dependent on manpower, which is time-consuming and laborious, inefficient and dangerous. Many people are unwilling to do it, and it is not easy to spend money on workers. "
With years of experience in maintenance and manufacturing, Wang Huazhong successfully developed a new type of slag scraper on the basis of cantilever excavator. A machine can replace the manual operation of a dozen people.
The slag scraper invented by Wang Huazhong obtained the national certificate of mine product safety mark, and the full-hydraulic backhoe loader (slag scraper) obtained the national patent in 2006, which has developed into five series and more than ten varieties, with nearly 2,000 customers at home and abroad, becoming the largest manufacturer in the same industry in China.
