- Q:The mechanical engineer applies for the condition English to say is must four above, but I did not achieve 4 levels, may have other ways
- It has nothing to do with the English class four. The mechanical engineer is divided into three parts: English, computer, and professional knowledge. English is very simple, probably on the college entrance examination, English is generally difficult to pass.
- Q:I want to sign up for a construction machinery rental company! What should I do? Steps? How much do you charge for a year?
- Registered company general search process: (the administrative department for Industry and Commerce), bank (bank), capital verification (accounting firm) to apply for a business license (the administrative department for Industry and Commerce) to apply for organization code certificate (Department of quality and technical supervision) to apply for tax registration certificate (tax authorities)
- Q:What methods and measures should be adopted for the maintenance of construction machinery?
- Such as bulldozers in operation, the engine suddenly stopped, the demolition found that the engine connecting rod bearings burned. Because there is no replacement on the spot, the solder is repaired by soldering, and the surface of the surface is smoothed and sized by a knife. After cleaning and loading, the diesel engine has been restored to work.
- Q:What are the differences between mechanical components and mechanical parts?
- According to the national economy sector, its range of products including investment manufactured goods machinery electronics and ordnance industry, belonging to the metal products industry, general equipment manufacturing industry, special equipment manufacturing, transportation equipment manufacturing, electrical equipment and equipment manufacturing industry, electronics and communications equipment manufacturing, instrumentation and cultural office the equipment manufacturing industry in the 7 major categories of 185 kinds.
- Q:Tianjin Construction Machinery Research Institute?
- The company has four subsidiary companies: Tiangong, central China, complete sets, the heyday, Tiangong and Tiangong works. The main functions of the subsidiaries are: Tiangong is responsible for industry services, product research and development and technical services; the whole set is responsible for exhibition, import and export trade and project contracting
- Q:How to make simple account for construction machinery rental?
- Bank loans: other business income, while carrying costs: other business costs: accumulated depreciation
- Q:What are the business scope of machinery and equipment enterprises?
- Construction machinery: forklifts, shovel handling machinery, compaction machinery, concrete machinery, etc..

Machine tools: metal cutting machine tools, forging machinery, casting machinery, woodworking machinery, etc..
- Q:What are the big countries in the world?
- Germany, the United States, China, Japan and so on. I haven't got the exact rankings yet. Also, Russia is powerful, huh?
- Q:Steel for construction machinery, including those concrete materials?
- Construction machinery steel include: welding parts with Q235A, Q345 (A, D), Q690 and so on. More than 45, 35 or more alloy steel. Sheet material: Q235A; 65Mn; 16Mn; 304 sheet (less used); cast iron class: HT150; HT100; a small amount of non-ferrous metal: 6-6-3; H62; copper tube and so on.
- Q:Do you have a promising future in the foreign trade of machinery industry?
- Most of the technical principle of mechanical products is very complex, it is generally difficult to fully understand the structure and use of technology and methods, but foreigners are very dedicated, generally involving imports of machinery products are the basic personnel and technical personnel, so when they discuss the transaction, can only put forward a lot of professional and technical personnel to be able to reply the complex problem, our domestic general foreign trade staff did not reply and exchange.
