Cummins in China The history of Cummings and China dates back more than half a century to the 1940s. On March 11, 1941, the President of the United States, Franklin Roosevelt, signed the Lease Act to provide wartime assistance to 38 countries, including China. The "Lending Act" includes military defense patrol boats equipped with Cummins engines and military trucks. At the end of 1944, a Chongqing company sent a letter to Cummins Corp. seeking to establish commercial ties and conduct localized production of Cummins engines in China. Irvine Miller, general manager of Cummins Engine Co., expressed great interest in this letter in his reply. It is hoped that Cummins will build a factory in China after the Sino-Japanese War. For reasons known to all, Mr. Miller's idea can only wait until the 1970s 30 years later. With the gradual relaxation of Sino-U.S. relations, it is expected to become a reality. Cummins and its affiliates have invested more than US$1 billion in China. As the largest foreign investor in the Chinese diesel industry, Cummins’ business relationship with China began in 1975, when Cummins’ chairman, Irvine Miller, made his first visit. Beijing became one of the earliest US entrepreneurs who came to China to seek commercial cooperation. When China and the United States established diplomatic relations in 1979, China’s opening to the outside world began. The first Cummins China office was established in Beijing. Cummins was one of the earliest western diesel engine companies to produce engines in China. In 1981, Cummins started to produce engines in the Chongqing engine plant. In 1995, Cummins' first Chinese joint venture engine factory was established. So far, Cummins has a total of 28 organizations in China, including 15 wholly-owned and joint ventures, with more than 8,000 employees, producing engines, generator sets, alternators, filtration systems, turbocharging systems, aftertreatment and fuel oil Systems and other products, Cummins service network in China includes 12 regional service centers, more than 30 customer support platforms and more than 1,000 authorized dealers in sole proprietorships and joint ventures in China. Cummins has long established a strategic alliance with large Chinese companies to achieve common development. As the earliest foreign-invested diesel engine enterprise to come to China for local production, Cummins has established four engine joint venture plants with leading companies of commercial vehicles in China, including Dongfeng Automobile, Shaanxi Automobile Group and Beiqi Foton, for more than 30 years. Fourteen of the three engine families have been produced locally in China. Cummins was the first foreign-owned diesel engine company to establish an R&D center in China. In August 2006, the engine technology R&D center set up by Cummins in cooperation with Dongfeng Corporation was officially opened in Wuhan, Hubei Province. In 2012, Cummins’ sales in China reached US$3 billion, and China has become Cummins’ largest and fastest growing overseas market.

Tower cranes typically use a combination of fixed and movable pulleys to lift and lower heavy loads. The pulleys are usually attached to the jib or boom of the crane and are used to change the direction and increase the mechanical advantage of the lifting system.

Some common types of pulleys used in tower cranes include:
1. Fixed Pulleys: These are stationary pulleys that are mounted at a fixed point on the crane. They change the direction of the lifting force and help distribute the load evenly.
2. Movable Pulleys: These pulleys are attached to a movable block that can be raised or lowered along the jib or boom of the crane. They provide additional mechanical advantage and allow for easier lifting of heavy loads.
3. Trolley Pulleys: These pulleys are used in conjunction with a trolley system that allows the crane to move horizontally along the jib or boom. The trolley pulleys help distribute the load evenly and provide smooth movement of the crane.
4. Counterweight Pulleys: Tower cranes often use a counterweight system to balance the load being lifted. Counterweight pulleys are used to attach the counterweights to the crane and ensure proper balance and stability.
It's important to note that the specific configuration and number of pulleys used in a Tower Crane can vary depending on the crane model and lifting capacity.
