Few operators are needed at the Sany Group's Beijing Rotary Drilling Rig Plant, as industrial robots are the leading employees when it comes to assembling machinery.
The smart factory, located in Changping District of the Chinese capital, was in September added to the World Economic Forum's Global Lighthouse Network, which recognizes factories showing leadership in the Fourth Industrial Revolution.
Notably, the factory in Beijing is the first heavy industry enterprise to be added to the list globally.
With a workshop area of four hectares, the futuristic plant is well equipped with 12 automated production lines and 150 robots.
Human workers have also been trained as technicians who can operate the robots directly, according to Dong Mingkai, dean of Sany's intelligent manufacturing research institute.
The factory has deployed a new manufacturing model with advanced human-machine collaboration automation, artificial intelligence and Internet of Things technologies.
The upgrade has served as a boost for production efficiency and product quality, as these innovations have managed to increase labor productivity by 85 percent and slash production lead time by 77 percent, accelerating from almost a month to just a week.
On the automatic assembly line for small and medium-sized parts, Automatic Guided Vehicle (AGV) and industrial robots connected to the 5G network can move freely on the ground. Together with truss manipulators, the devices are able to position, grasp and assemble machinery parts in an orderly manner.
Nearly 30 model varieties can be produced with the help of robots and core intelligent technologies including laser and visual sensing, working to meet the growing demand for multi-category and small-batch flexible assembly and take a lead in the whole industry, according to Dong.
The factory's number of human workers has decreased from 2,000 to just a fifth of that, while the annual volume of equipment produced has soared from 1,000 to 3,000 units, said Dai Qinghua, director of the Sany Group.
As China promotes green and low-carbon development, and promises to peak carbon emissions before 2030 and achieve carbon neutrality before 2060, the country has reached a consensus to promote a more eco-friendly engineering machinery industry.
The "lighthouse factories" represented by Sany Group's Beijing Rotary Drilling Rig Plant are just one example of Chinese enterprises' unremitting pursuit of high-quality and low-carbon development through digital transformations.
"The plant is resource-saving and eco-friendly, and its demand for and consumption of electricity are obviously decreasing," said Tang Xiuguo, president of Sany Group. He said the power generated by the group's self-sustaining wind power plant has far exceeded the power consumption of all its factories.
"Sany Group will actively explore the applications of new energy to save energy and improve energy efficiency. And existing construction machinery products built with diesel engines and petrochemical energy are expected to rely on electricity in the future," Dai said.

一条条装配线整齐排列，自动导引运输车(AGV)来回穿梭，身形庞大的工业机器人举重若轻，一台台搭载视觉传感的机械手臂不停舞动，组装着精密的工件。偌大的工厂整洁有序，却看不到几名工人……
走进三一重工北京桩机工厂，这样颇具“科幻感”的画面已成为现实。
近日，世界经济论坛正式发布新一期全球制造业领域“灯塔工厂”名单，三一重工北京桩机工厂入选，成为全球重工行业首获认证的“灯塔工厂”。据了解，“灯塔工厂”是“数字化制造”和“工业4.0”的示范者。
三一重工智能制造研究院院长董明楷介绍说，三一重工北京桩机工厂01号厂房占地面积为4万平方米，在2020年销售额78亿元，每平方米厂房的产值超过20万元。
与此同时，随着工人数量减少，单位人均产值也大大提升。“因为我们把大量的工人转变成为技术工人，直接操作机器人，来实现自动化和数字化的升级，全面提升我们制造的水平和响应市场的能力。”董明楷说。
据介绍，该工厂打造“以工业数据驱动生产”的智能制造新模式，部署先进的人机协作自动化技术、人工智能和物联网技术，完成智能机器人在生产运输等环节全面应用，自研“智能工厂大脑”，实时洞察生产运营状态。
升级后，总体生产设备作业率从66.3%提升到86.7%，平均故障时间下降58.5%，劳动生产率提高了85%，生产周期缩短了77%，生产效率及产品质量均大幅提升。
在中小件自动装配线上，地面上任意移动搭载5G的AGV和工业机器人，与空中的桁架机械手协同作业，井然有序地完成工件的定位、抓取和装配。董明楷介绍说，工厂的装配自动化水平已超70%，搭载了激光传感技术和视觉传感、机器视觉等核心智能技术的机器人“长了一双慧眼”，能够实时感知并且利用不同工装抓手适配不同型号的工件。据了解，该工厂可生产近30种机型，实现了多品种、小批量的柔性装配，“柔性智造”水平全球领先。
三一集团董事、高级副总裁代晴华表示，改造升级投资基本上在三年左右就可以与节约的人工成本相抵。“这条自动装配线此前需要10多个人操作。改造完成后，1位工人就可操作。整个厂房产能从以前2000人完成1000台设备，到现在全年400多人可以实现3000台设备的生产。”他说。
随着中国推进绿色低碳发展，并承诺力争2030年前实现碳达峰、2060年前实现碳中和，工程机械绿色发展已成为共识。
从中国制造到“中国智造”，以三一重工北京桩机工厂为代表的“灯塔工厂”是中国企业追求高质量发展之“变”的缩影，也折射出企业通过数字化转型助力节能减排的新努力。
三一集团总裁唐修国在接受采访时表示，作为全球重工行业首获认证的“灯塔工厂”，三一重工北京桩机工厂资源节约，环境友好，对电的需求和消耗均呈明显降低趋势。与此同时，三一集团自持风力发电厂的发电量已经远超其所有工厂用电量。
“我们要做到的就是不断地提升有效作业，作为降低能耗的手段。另外也通过管理去降低消耗。”北京三一智造科技有限公司总经理李梁健说。
代晴华表示，三一集团将以进一步节约用能、提高能效为方向，积极探索新能源转化，大力推动现有以柴油机、石化能源为主的工程机械产品的电动化。
