On September 1, 2013, the reporter learned from the commemoration of the 5th anniversary of the first tire of Shuangqin Group's Chongqing company that its daily production level has exceeded 6,000 units and the annual production capacity of 2 million sets of tires has been formed. This means that the tire production capacity of its Shuangqiao Economic Development Zone is second to none in the southwest region.
It is reported that Shuangqin Group Chongqing Tire Co., Ltd. is a key industrial project introduced by Shuangqiao Economic Development Zone. It started construction in September 2007. On August 28, 2008, it successfully achieved the first tire off the assembly line, and reached its annual output in the second year. Tire 1.2 million sets of production capacity. On June 9, 2013, the company's Nissan level exceeded 6,000 units, forming an annual production capacity of 2 million units.
After five years of development, Shuangqin Group Chongqing Co., Ltd. has become the largest tire production base in the southwest with five series of double money, pull back, leapfrog and MasterCard, and has 19 national patents, among which invention patent 3 The items are listed as "high-tech enterprises in Chongqing" and "innovative pilot enterprises in Chongqing". The annual output value of the company exceeds 2.5 billion yuan, and the annual profit and tax exceeds 100 million yuan, becoming the largest taxpayer in Shuangqiao Economic Development Zone.
Mr. Chu Zhengyu, party secretary of Shuangqin Group, introduced that Shuangqin Group currently has five tire production bases in Shanghai, Jiangsu, Chongqing, Xinjiang, and Hangzhou, forming a production capacity of 10 million sets, ranking second in the country. At the same time, the car tire production base jointly built with Michelin tires is booming in Anhui with a design capacity of 15 million sets. By then, Shuangqin Group will become the largest tire manufacturing enterprise in the country. Shuangqin Group will turn the Chongqing company into the most advanced, greenest, most productive and best-quality tire manufacturing enterprise in Southwest China, and make greater contribution to the economic and social development of Chongqing and Shuangqiao Economic Development Zone.
Some of electric parts for Tower Crane:
1. Electric motor: Tower cranes use electric motors to power the lifting and rotation mechanisms. These motors convert electrical energy into mechanical energy to move the crane's various components.
2. Control system: Tower cranes require a sophisticated control system to manage the movement and operation of the crane. This includes controls for lifting, lowering, slewing, and trolleying.
3. Limit switches: Limit switches are used to set the maximum and minimum positions of the crane's various components. They help ensure safe and accurate operation by preventing the crane from exceeding its designated limits.
4. Power cables: Tower cranes require heavy-duty power cables to transmit electricity from the power source to the crane's electrical components. These cables need to be durable and capable of handling high voltage and current.
5. Circuit breakers: Circuit breakers are essential safety devices that protect the crane's electrical system from overloads and short circuits. They automatically interrupt the electrical current flow when a fault is detected, preventing damage to the crane and reducing the risk of electrical fires.
6. Transformers: Transformers are used to step up or step down the voltage of the electrical supply to match the requirements of the tower crane. They ensure that the crane receives the correct voltage for optimal performance and safety.
7. Sensors: Tower cranes often incorporate various sensors to monitor and control different aspects of their operation. These sensors can include load sensors, wind sensors, angle sensors, and anti-collision sensors. They provide crucial data to the control system, helping to ensure safe and efficient crane operation.
8. Emergency stop switches: Tower cranes are equipped with emergency stop switches that can quickly shut down the crane in case of an emergency or safety hazard. These switches are strategically located and easily accessible to crane operators.
