As the company is located in the commercial and residential area planned by the government, it is impossible to expand and build new factories. In response to the call of the government to become bigger and stronger, with the care and help of relevant government departments at all levels, the company signed an agreement with the Longquan District People's Government and the Economic and Technological Development Zone Management Committee on the "Chengdu Shenzhen-Hong Kong Group Billion Relocation and Expansion Project" in June 2007, and acquired land 1350 mu in Chengdu Economic and Technological Development Zone. It is planned to invest 3.4 billion yuan for relocation and expansion projects. With three years of construction and development time, the comprehensive production capacity of 20,000 wheel loaders, 6,000 medium and large hydraulic excavators and 3,000 small excavators will be realized by 20 10, and the annual sales income will be1500 million yuan.
In June 2008, the groundbreaking ceremony of the 10 billion construction project was held as scheduled in Longquan Economic Development Zone. The whole project is divided into excavator project, loader project and comprehensive office building project of group company, which is carried out in two phases. The excavator project officially started in September 2008, and the project entered the main construction stage in June+February 5438. In June 2009, the new excavator factory was put into production, and a grand completion ceremony of the excavator project was held in the new factory in February 2009.

Mass production of new machines (SK200-8, SK2 10LC-8, SK250-8, SK260-8) began in June 2006. On this basis, production of improved models of new machines began in June 2009. Production of13t-14t (sk130-8, SK 140LC-8) aircraft began in September 2009; Production of 33 -35 tons of machinery (SK330-8, SK350LC-8) began in July of 20 10, and 65438+7.5 tons of machinery (SK75LC-8) was put into mass production in February of the same year.
In the future, it will also introduce the latest model designed by Japan, with a class of 6 tons, to contribute to China's mechanical construction. At present, the products are mainly for the domestic market in China, especially in East China; At the same time, it is an effective part of the global production system of Shenzhen-Hong Kong construction machinery to make full use of the advantages of convenient transportation in coastal areas, actively carry out export business, and provide some structural parts needed for the production of excavators to the United States and Italy, such as crawler beams and booms. Different from the past, it always pays attention to increasing the workload of the machine at the request of customers;
Not simply pursuing lower fuel consumption and lower cost economy;
It starts from various interrelated viewpoints, such as cost and effect, present and future, consumption and environment, preservation and use, region and world. 65438+
2. The alarm of Kobelco was reversed, and then it suddenly turned off automatically. Most of the faulty parts are the damage of the oil pressure sensor.
3. The whole car of Kobelco can't catch the car, and the action is slow. Basically, the pressure sensor of the hydraulic pump is damaged (alarm C 1C2).
4. Keys and display screens are also easily damaged in Kobelco.
5. In Shenzhen and Hong Kong, Chengdu, the pressure sensor is easy to be damaged, so the sensor can be replaced according to the alarm. There are often CPU alarms in Shenzhen and Hong Kong, Chengdu, and the CPU ROM alarm needs to be adjusted, and other CPU alarms need to be repaired.
