SEM921 leveller -- "flat ground pioneer" of mine working condition;Meet the needs of work, strong and durable, reliable and efficient.

The rainy season in the southwest region of China begins in June. No matter. In the Xinying brickyard of YanShan County in Yunnan Province, workers are clad in rain hats and boots – otherwise seeming not to notice Mother Nature`s heavy downpour. Still, the work at hand continues as do three yellow SEM wheel loaders, moving material at a steady pace. Bad weather hasn`t affected production here for decades. In the corner of the yard, there`s a carefully placed, retired SEM 50F wheel loader, representing 11 years of determination and achievement. All the workers know why it`s there. The story begins with the Ma brothers: Zewen Ma, the eldest; Ma Di, the middle brother; and Zebin Ma, the youngest. In early 2007, the brothers – noticing a thriving construction industry – pooled their funds to purchase a brickyard. At the time Zewen Ma was engaged in retail, Ma Di was in the transportation business, and Zebin Ma was a truck driver. It was a leap of faith for the brothers, and though a bit risky, for Zebin Ma, the change was a welcome end to the dangers of being beaten and robbed while driving a truck. Preparing for operations, the brothers traveled to Kaiyuan City to purchase a wheel loader for the fledgling business. [We didn`t know how to choose among the variety of brands," recalls Ma Di. [SEM wheel loaders attracted us once we put eyes on them, providing us with a feeling of durability and safety. We felt destined (for success) with SEM wheel loaders." They bought a SEM 50F wheel loader and returned home. Once in the brickyard, the 50F did not disappoint. It was durable and could work in punishing weather, lifting stones and cement, digging foundations, and transporting steel and wood. To the brothers, the machine worked like an energetic youngster, supporting all facets of the brickyard operations. Settling into individual roles, Zewen Ma assumed responsibility for operations, Ma di drove the 50F, and Zebin Ma led workers who produced the bricks. As business increased, the brothers worked even harder, paying careful attention to production safety and quality. As they learned, the business grew, and so did profits. Five years later, by 2012, the brothers had purchased two additional brickyards, one in Pingyuan County, to meet increased demand. In 2017, they added new wheel loaders to the Xinying operations: In ten years` time, the Ma brothers had purchased five SEM wheel loaders for their three brickyards. [Every business must begin to be profitable within three years," said Ma Di. [SEM wheel loaders greatly improved our work efficiency, making our business profitable within one-and-a-half years!" Along the road to success, the brothers were committed to giving back to the community and improve local living conditions – assisting in emergencies, helping rebuild roads and moving mud during devastating rains. When a nearby reservoir was pushed to the breaking point after heavy rains, threatening neighboring farms and cottages, the Ma brothers gathered together workers and the old 50F to build a new dam. Future plans include a modernization of the original Xinying brickyard, with an eye toward improved safety and sustainability processes. SEM will be there – helping the brothers and their customers build a better world. As for the old 50F? It`s retired from daily work, instead standing in the yard – a testament to what perseverance can achieve. To Zebin Ma, it`s more than just a machine.[The old wheel loader helped us through hardship, and we all have brotherly emotions about it," he says wistfully. There have been offers to purchase the machine, but the brothers agree: It`s too valuable to be sold for any reason. They still bring it out occasionally for small jobs or as a temporary replacement for machines in repair. And sometimes they drive it just for the memories.

For more than 90 years, Caterpillar has contributed to the various communities where we live and work around the world. SEM, as a brand of Caterpillar, has followed that example by promoting better living environments, education, training and the general welfare in Qingzhou City, where it is located. There are about one million people in Qingzhou City, including nearly 300,000 urban residents. People from around 5,000 local families are working for SEM or its related organizations. If a family includes five or six members, that means there are tens of thousands of people living in this small city with a direct or indirect relationship with SEM. One citizen describes the relationship like this: [SEM provides us secure lives, benefiting us a lot." Mr. Dan Gives his Time for Charity On the banks of the Pushui Stream, six kilometers southwest of Qingzhou City in Shandong Province, there is a place called the [Camel Mountains." The mountains there look like camel humps stand together, filled with Buddhists and temples. At the foot of the mountain, you can see a stunning three-story building with gray-white walls. It is the newly-renovated Tuoshan Elementary School, funded by the government. One day in October of 2016, a bus full of SEM volunteers stopped at the school. Pupils welcomed them at the gate with the greeting, [Welcome our brothers and sisters to our new school!" They stopped the chants suddenly when people stepped off the bus. A tall, smiling man started saying hello to them. The man was Dan Herkelman, then the general manager of the Earthmoving Operations Department in Caterpillar. The students gave him the nickname [the tall teacher." Dan often travels from China to the U.S., but once he learned about the school, he decided to spend a day there. Once in the class, Dan was excited to share new words with the students, and they were excited to share their interests with him. After class, they went to the newly-stocked library, a sight of particular interest to Dan. [My father has been a math teacher for 50 years. I also dreamed of becoming a teacher and my dream came true in a special way here. Knowledge can make your dreams come true!" The students were inspired by Dan`s words. No Need to Line Up for Lab SEM has always taken its social responsibility in education seriously. SEM provides professional training, employment opportunities and public hardware to cultivate technical talent in the city in which it is located. It came to SEM`s attention that nearly 400 graduates from Weifang Engineering Vocational College annually major in fields such as Electromechanical Integration and Construction Machinery Application. Yet, practical training for those skills was still being outsourced. Caring deeply about education, SEM understood the urgent request from the college for practical training facilities. As a result, SEM built a Caterpillar Training Center and assigned experts to bolster the professional faculty and curriculum development. The Caterpillar Training Center Leaders of SEM and College Visit Training Center Weifang Engineering College teachers and students were immediately impressed with the Training Center, with some exclaiming, [We don`t have to line up for a practical training class!" Some students also said: [After a couple of classes in the Training Center, we felt it was more professional. With the advanced equipment and reasonable curriculum schedule, we are totally confident that we will get solid knowledge and be able to fully use it in practice." The Training Center can not only accommodate 600 people taking training together, it can also meet the requirements for training on Mechatronics, Engineering Machinery Application and Maintenance, CNC, and other professional skills. Since it opened in July 2010, there have been more than 3,000 outstanding graduates from the school who are now employed in various industries. In addition to the training for Weifang Engineering Vocational College students, the Caterpillar Training Center also provides training for other students, both domestic and international. One thousand domestic people per year can join the training class held in the center to receive the systematic education and operational training on advanced equipment. Many students from countries involved in the [Belt and Road" infrastructure construction initiative will also be training at the center as technology talents. In return, Weifang Engineering Vocational College opened the SEM training class in 2008, providing detailed courses related to the Caterpillar Production System, 5S and 6 Sigma management. All the courses and training were aimed at providing professional talent for SEM. Help Arrives From Overseas During the Dragon Boat Festival in 2013, Paul Blackburn, who was then chairman and general manager of SEM, suddenly passed away. His family knew Paul and Caterpillar were devoted to public charity in China, especially when it came to education. During his lifetime, Paul often visited the Weifang Engineering Vocational College, demonstrating his love for the students there. As a worthy memorial to Paul, his family elected to donate money to the college and create the Blackburn Scholarship to inspire and assist the students who are outstanding academically, but financially challenged. The scholarship stands as a lasting tribute to Paul Blackburn`s love of Weifang Engineering Vocational College. Chao, one of the winners of the 2017 Blackburn Scholarship, is a student who came from a farming family. Normally, his family would have been under big financial stress to support his college work. And they worried about him finding a steady job after college. But all their fears were alleviated when Chao was introduced to the SEM culture, enrolling in a SEM training class, learning the Caterpillar culture and ideas, obtaining the professional skills in the training center, winning the scholarship with a sterling academic score and getting the internship opportunity with SEM. [I would never have dreamed what has happened to me, receiving an international education in my hometown, getting the great job and even receiving the care and love from overseas. I`m grateful for Paul and his family`s donation. I will definitely work hard to contribute to the company and pass on this love to help more people," said Chao, with full gratitude. So far, 48 students like Chao have benefited from the Blackburn Scholarship. Starting in 2008, the college has established 15 SEM classes with more than 600 graduates. In additional to those with other majors, nearly 100 students every year are hired by SEM. People who love and respect others will be loved and respected in return. SEM has shown its commitment to social responsibility through its actions. From 2001-2006, SEM built roads and dug wells for more than ten villages around the city, providing local residents with convenient water sources. From 2004-2007, SEM donated RMB 100,000 in the form of goods or cash to the Qingzhou Yunhe Middle School and the Dongguanhui Secondary School to improve their educational facilities. In 2008, SEM donated more than RMB 40,000 for the snow disaster in south China and RMB 803,000 for the earthquake-damaged region in Wenchuan. In 2010, SEM donated wheel loaders to the quake-hit region in Yushu in addition to RMB 501,400. In April 2016, SEM launched a program [Child Care to Special Needs in Qingzhou Special Schools." Since 2014, SEM, together with other Caterpillar organizations, has participated in public planting charity activities, donating more than 340,000 saplings, estimated to achieve 55,151 tons of annual carbon reduction, 38, 463 tons of oxygen release and more than 8,506 kilograms of dust retention. Caterpillar believes the sustainable development of the communities where we work and live around the world is a responsibility and an important part of the company`s development strategy. The foundation of The Operation Strategy Seminar of SEM - [Being a Respectable Company" - is not only a promise for the future but a reflection of the past. SEM will continue its effort to provide high quality products, excellent services and the fulfillment of its social responsibilities in contributing to the sustainable development of its communities.

Ding Jifu remembers April 2nd, 2002 well. It was his 15th birthday. It was also the day his father brought home a yellow SEM 50D loader, nicknamed [The Willing Ox." During that first year, the Dings` yard was the parking lot for the loader. Ding became interested in the machine, often walking around it and even driving it, which made him the envy of his friends. Ding Jifu`s family was living through challenging times financially. His eldest sister was at college. Ding`s father, who had been a truck driver, bought the wheel loader with loans in hopes of making money for his family and covering his daughter`s tuition. He kept the loans secret from his children. But he was driven by the conviction that if he worked hard, the money would come. The first year was tough. Ding quit school at age 16 and worked with his father and [The Willing Ox" to share the heavy family burden. He recalled that they were first hired by a road construction company to stack material and paid 120 yuan per hour. To complete the project quickly, Ding would get up at 4:30 a.m. and work with [The Willing Ox" until 6:30 p.m. They were then hired by a quarry far from their home, so they rented an apartment near the work site. Ding`s mother moved too so she could take care of them. Ding still remembers how stressful those days could be. [Once I worked 72 hours without a break. When you are that exhausted you can`t even fall asleep." Most work sites were remote and barren. Operators had to eat and even sleep on the machine. A few stuffed buns and some fried pancakes often were their meals for the entire day. Ding said his father was worn out and had eye hyperemia. His eyes were full of tears all the time and his vision blurred. At that time, the father and son took day and night shifts to operate the wheel loader around the clock. Ding said since he was young and strong, he volunteered to take the night shift so his father could rest as night as usual. Despite the hard work and grueling hours, they never ignored the maintenance of the equipment and took good care of it. Located to the south of Laizhou Bay, the Yangkou town that the Dings live in is home to the largest and most efficient fishing fleet in Shandong Province. It`s known as the [Captain of Shandong." In addition, it is also an important crude salt producing area in China. In 2004, the town invested more heavily in industrial development and became dedicated to the development of chemical products with crude salt, which brought great opportunities for the Dings. Ding and his father operated the loader once again day and night at the construction sites. [We just wanted to change our lives with our diligence," said Ding. By 2007, the Dings had paid off the loan on the first loader. A year later, Ding`s father bought another SEM loader. He believed the loader was of high quality, durable and powerful. And in 2010 there was a third buy. Ding felt pressured because they had just bought a house with loans and were looking at shouldering loans totaling as much as 1 million yuan. [I was depressed at that time and seldom talked at home," Ding recalled. [I worried when we could pay off all the loans. I even sobbed in front of my mother." [At that time, we couldn`t afford medical bills and knew we must work even harder. In a way, our first wheel loader shared a similar fate. Though we had operated it for 16 years, its gearbox had never been opened, only two tires replaced and the other original tires were still in use. It was a miracle," Ding said. [But when I started to work at the chemical plant and at other businesses, our situation improved. By 2013, all the loans had been paid off. It was a remarkable relief for my family." The lesson was if you treat it well, it will repay you. These [willing oxen" have done a magnificent job for the Dings and continue to thrive at work sites today. Ding has already started his management work, but he will never forget those tough days. Ding`s father has retired, but occasionally helps Ding take care of the [willing oxen." Ding`s mother had double-knee replacement surgery in 2017. [At that time, to save money, my mother rode a motorbike to bring us food, instead of taking the car," Ding said. [Their love and dedication has paved an easier path for me so that I can have a happy family and a comfortable life." The construction machinery industry draws tens of thousands of young entrepreneurs like the Dings who are hardworking and reliant on their [willing oxen." Those entrepreneurs and their machines form strong relationships as they contribute to the rapid economic development of China. Together, they have created an environment for happy lives across China.

Part One of SEM 60-Year History An area of barren land populated only with eight straw houses, five open sheds and 22 workers. It is often difficult to reconcile the humble beginnings of SEM 60 years ago with the SEM brand of today. But the founders of SEM understood that success came only with hard work and dedication to excellence. SEM grew from a manual workshop to an international brand with a sales network covering more than 80 countries and regions. TV2 series electric cucurbit in 1970s Agricultural machines and joint cutter for cement produced in 1970s From Electric Cucurbit to The First Wheel Loader Prior to 1973, SEM products such as threshers, peeling machines, grinding machines and tractors were designed for agricultural use. In the early 1970s, the launch of the electric cucurbit and joint cutter for cement sent SEM down a new road of development. During those years, the leadership of the factory traveled to Beijing to deliver joint cutters for the construction of the Capital Airport. At that work site, the team, by accident, saw a wheel loader, a rare sight in the early stages of the Chinese engineering machinery industry. On the train back to Shandong, the team enthusiastically discussed the possibility of expanding the factory`s production scale to produce wheel loaders and secure an exciting development direction for the future. As soon as leadership team returned, they conducted market research and concluded the trend of infrastructure construction across China meant an urgent demand for wheel loaders. During the planned economy era, only a handful of state-owned enterprises were authorized to produce construction machinery. SEM was not on the list. Getting design drawings was one of the biggest challenges for the founders. After several twists and turns, the leadership eventually purchased wheel loader drawings from the market with 100 Yuan and started production trials. Most of the parts, including the gearbox and the hydraulic cylinder, were produced and assembled independently. Without production experience, they were forced to study the drawings millimeter by millimeter. They discovered the steel supply was insufficient, so they went to the machinery bureau and small factories to coordinate resources. With a limited workforce, the leadership focused on efficient production and management. With those efforts, the first JZ425 wheel loader was successfully trial-produced in May 1977. An Instant Hit Across the Industry In 1978, one order after another opened a new world of opportunity for SEM. The fledgling JZ425 was selected by the National Ministry of Metallurgy. The first batch of 9 wheel loaders was sent to support key national metallurgical departments. In 1979, based on market feedback, the factory upgraded the JZ425 wheel loader and won good market response. During this period, SEM forged a important relationship with Tianjin Engineering Machinery Academe, a renowned authority on construction machinery. From 1980-1983, the two jointly developed the first scrap loader grasper. In 1984, they jointly developed the first ZL25A wheel loader. Its single plate lift arm, single-rocker arm, horizontal-lifting cylinder and automatic leveling bucket design was domestically invented. JZ425 sent to national key metallurgical departments in 1978 1983 was a year of great significance at SEM. The SEM wheel loader participated in the national 500-hour reliability contest in Liuzhou, Guangxi Province. At the time, there were [four big families" in domestic construction machinery. SEM was not considered part of that group. However, in the four-month test, the SEM wheel loader performed with excellent endurance and quality, ranking number one in attendance, reliability, noise and sealing. After the results were announced, representatives from the state-owned factories were surprised and praised the [unknown" SEM. With an extraordinary performance in the competition, SEM instantly won recognition of the industry. SEM University Cultivates Talents The forward-thinking founders of SEM understood that a company`s most valuable asset is talent. In the 1980s, university graduates were allocated by the state, usually sent to state-owned enterprises and institutions. As a township company, it was difficult for SEM to obtain technical talent. The sustainable development of enterprises demands sufficient research and management personnel. Factory leaders determined SEM needed its own university in order to cultivate the needed talent. SEM set up a television university training course, enrolling the first group of 90 students who failed that year`s college entrance examination and inviting leading scholars to conduct the tutoring. The students diligently studied. After graduation, they became the backbones of each department by devoting themselves to the practical work and playing a pivotal role in SEM research and development. From 1958 to 1985, nearly 30 years of arduous work, innovation and courage had formed the foundation for SEM`s rapid development and created a home for SEM employees. The leaders` pioneering spirit and vision, pursuit of excellence and attention to cultivating talent had pushed the once unknown factory in Shandong to the fast track of international development.
