From 2004 to 2012, during an eight-year period, Rock deeply understood the chaos in the Chinese crane manufacturing industry. Manufacturers produced equipment of varying quality based on customer demands, as they were neither standard setters nor standard enforcers, driven solely by profit, and lacking integrity. In 2013, Rock founded CLESCRANE with a spirit of craftsmanship, diligently learning from European crane manufacturing companies, daring to innovate, focusing on products, and focusing on customer experience. Aiming to pursue quality, benefit more users, help clients enhance their business development, and grow alongside with customers.
