For people in the construction business, not much thought is given to the history and evolution of heavy construction machinery. People go to work every day to build houses, office complexes bridges, waterlines, move lumber, reach street lights, and the list goes on and for all these jobs to be completed successfully special equipment is required. You could say that when people try to find a forklift for sale, Freightliner Fl50, or perhaps a Case 1840, the only thought is finding the right machinery at a good price, not how machinery has come.

However, with so many changes over the past several decades, it is important for people who work with heavy construction machinery to understand a little bit of history, as well as the types of changes see and expected changes for the future. For this reason, we wanted to provide a better understanding regarding changes specific to these machines.

It is important for people to remember that in addition to materials and workmanship improving, technology has also made a significant impact on contracting equipment used in today’s work environment. Construction company owners and managers have a huge responsibility to keep current on the various types of equipment produced and then determine if it would benefit their specific business. Whether an avalanche pickup or F250 truck, technology is making work easier, more convenient, faster, and safer.

One of the key factors when choosing any type of heavy construction machinery is quality. Obviously, when higher quality materials are used, the equipment can withstand more demand and last much longer. Then when workmanship and design of contracting equipment is high quality, operations would be seamless. Another important aspect of heavy construction machinery is that because so many are designed with state-of-the art technology, operation is done by a highly trained professional.

The operation of any type of machinery has a primary function of keeping the equipment in excellent condition so the company experiences no down time. The more the machine operates at peak performance without being out of commission the easier it is for the company to stay below budget. In addition, because of new technology and automation for construction machine’s functionality, fewer people are needed for various jobs, allowing the company to utilize the extra people in a different capacity.

Today, many types of heavy construction machinery are designed with computerized systems. Although an operator is still needed for operations, many of the older processes are now being done by the system with the operator overseeing the equipment’s functionality. Some designers and researchers of heavy construction machinery are now looking at a methodology called “work cell”, which is a newer type of technology still in the works.

The concept of the work cell method specific to heavy construction machinery is that a single operator would work from a primary work station but instead of operating a single piece of heavy duty equipment, two or three different pieces of equipment would be operated. However, to make this concept a reality, all of the machines being operated would need some type of sensory or automated control so certain functions would be handled automatically. Without doubt, heavy construction machinery has come a long way and it appears the future will be even more incredible than it is today.

From the export data of 2009, the export value of Chinese engineering machinery was 7.121 billion U.S. dollars, down 39% year-on-year. The import value of construction machinery in 2009 amounted to 4.773 billion U.S. dollars, down 16% year-on-year.

The monthly export value of Chinese construction machinery in 2009 was approximately equivalent to the basic level in 2007. The export figure of 2008 was very high, so the year-on-year growth of 2009 was negative. Taking into account of the pick up of external demand in 2010 and low base of the overall data in 2009, the year-on-year growth of export value is expected restored to the level of 50% in 2010. Because of the strong demand from Chinese domestic market, the decline of import value was not very obvious in 2009. As of 2009 November and December, the year-on-year data had turned positive, showing quite obvious recovery. It is expected that the import value of construction machinery will increase about 30%.

In the past decades, die and mould industry keep increasing with a speed of average 15%, and the forms of ownership in die and mould industry changed a lot.

With the ever-increasing integration with international companies, the competition among companies is more and more fiercer, manufacturers begin to realize the importance of the quality and cost of the products, and the manufacturing of the die is the most important link in the whole process. Now more and more die companies invest more money to increase die technology. Some die companies have popularized some software such as two-dimension CAD, UG, Pro/Engineer, I-DEAS, and so on.

The development of the die technology should adapt to the following requests, we should short the manufacturing time and price, improve the precision and the quality of the product, in order to reach these requests, firstly, we should popularize the CAD, CAM, CAE technology, now according the development of the software, the condition for popularizing the CAD, CAM, CAE technology is ripe, all kinds of training centre are committed to teach workers how to operate the software, which makes the development of the software keep increasing. Secondly, the high speed milling technology gives rise to the change direction of the die and mould industry. The technology of high speed milling spreads all around abroad, this causes the increase of working efficiency and can get low surface roughness, which makes the development more agile, more intelligent.

Thirdly, better material and advanced surface processing technology, it is necessary to select choice steel and suitable surface processing technology to improve the life of the die, so when the trend of die’s heat treatment is through using vacuum technology.

Fourthly, the quality of die’s surface plays an important role in the life of the die, so it is a good idea to do research about grinding automatically and intelligently, which can replace manual operation.

Fifthly, the development of automatic manufacturing system in die and mould industry, this is the target for the long developing plan, automatic manufacturing system about die should combine more than one machine tools, the system should have location chuck, positioning plate, tool database, the entire numerical flexible synchronous system and quality-monitoring control system.

Above is the trend and current situation of die and mould industry.

How bout the current situation and analysis of our country’s construction machine leasing industry? What is the market demand and the existing issues about construction machine leasing industry? Now China construction industry association does a survey about the current situation and future development of China construction machine leasing industry, the survey is done by a questionnaire and the interview with the important companies, 63% of the companies which join in this survey are construction machine leasing companies, the rest of them are construction enterprises.

Now we talk about the current condition about construction machine leasing industry. Our country’s construction machine leasing industry starts later than foreign countries’, and the scale is not big enough. The origin of this industry dates back to the 1990s, and with the ever increasing development of the enterprises, state-owned, private, joint venture, personal construction machine enterprises develop rapidly, for example, in Beijing, the numbers of the companies which is engaged in leasing are 400.

Here are the questions which the enterprises care about.  The key to determine whether the transaction is success or not is the leasing price, and the proportion of this factor is about 25.8%,which is followed by the band reputation of the leasing company, which is about 20.4%. The questions which the enterprises care about are rent arrears which occupy 50.7% of the whole, the standardization of the market which is 46.4%, the third one is the development of the band.

According the survey, here are some advices for the future development of this industry. Firstly, we should change the business concepts, and create new kinds of leasing mode. Secondly, build new leasing enterprises which are more professional and have their own bands and scale. As is known to all, the quantity of enterprises which are more professional and have their own bands and scale in machinery represents the developing level of the whole machinery. Thirdly, apply scientific managing method, and lower the credit risk. Fourthly, create differentiated services, and improve the competitiveness of the enterprises. Focusing on selling and ignoring service is the general problem existing in today’s construction machine leasing machinery, the conception of doing well in service is not only focusing on improving the satisfaction of the existing service, but also thinking about how to apply customers with underlying demand. So improving the service quality and making diverse service projects to satisfy customers will increase the quantity of the leasing transaction.

In a word, let government authorities, industry association and enterprises cooperate with each other fluently, and make a just, fair, orderly environment for the leasing market.

As is known to all, the heavy machinery can be simply divided into several groups such as construction machinery, engineering machinery, crane, metallurgy machinery and so on, and according to the application of the product and the actual use of the product, we can divided it into other catalogs.

Today, we’d like to introduce something about construction machinery, first, the definition of construction machinery. Those machines which are used in the process of construction is called construction machine, and these machine can make the building more stable, and make the time of completing the building shorter. Construction machinery can be subdivided into construction device, road equipment, garden machine, crane, excavator, earth-moving machine, and so on.

Currently, the globalization of the economy is the general trend of the world economy, since China joined the WTO, the speed of China’s integration into the world economy accelerates rapidly, so from now on, one trend of our country’s construction marketing is toward internationalization, standardization and the diversity of the marketing. Because of these changes in construction marketing, it affects several aspects of the construction marketing in China. Firstly, the general trend of investment in our country’s marketing is increasing, and it does bring the opportunity toward the development of the construction machinery. Secondly, the integration of the domestic and overseas market, and it did bring great opportunity and challenge to enlarge the international contract market. After we enter the WTO, all the members which join the WTO have to share information with each other, and have no excuse to turn down members illegally. Because the reduction of the tax, we can low our cost, in that way ,we can also enlarge the importation of the material, all these issues is benefit for the development of the economy.

Thirdly, the environment of the construction market is becoming better, at the present, a lot of issues in construction market exist, but the general trend about domestic market is towards the sound, the standardization and the perfection of the one.

Fourthly, more and more foreign investment flow into construction companies in China, and it brings the fierce competition among construction market, through the competition, we can reduce the gap between domestic and overseas marketing.

In a word, from now on and in the following years, it is a good opportunity to develop the construction, although we may meet a lot of challenges, we can tackle them and have our own market occupation in the construction market.

Nowadays all kinds of machine tool have been used in manufacturing industry, such as turning, milling, grinder, planer, and so on, but among them, milling machine is the most useful machine tool, because we can produce complex surface through using milling machine. Today, we will study and know a new kind of milling machine which is famous for its high efficiency and cleanness, it is called whirlwind milling machine. Whirlwind machine is a kind of machine which we add the high speed thread devices to normal turning machine, through using CBN tool which is clamped in the high speed milling cutter, we can mill the thread on the workpiece, because of its high speed which is more than 400m/min, high working efficiency, and cool strategy which use compressed air to get the chips out of the thread of the workpiece, it is becoming more and more important and popular. Whirlwind machine can also realize dry cutting ,heavy load cutting and ultra high speed cutting, the surface roughness can reach 0.8 um, because the turning speed of spindle is slow, so the motion accuracy of machine tool is accurate, and we can get high dynamic stability. Here are the motion of the whirlwind machine, the main motion is the high speed turning of the mill cutter, the supplementary motor is the slow turning of the machine tool with clamped workpiece, the feed motor is the slow movement of the mill cutter at x direction, and we should adjust the angle of the mill cutter according to the thread lead angle. The application of the whirlwind machine is spreading all kinds of machinery, for example, the sprite which we drink when we feel thirsty is involved in using this technology, we can manufacture the cap using whirlwind machine, and we can also manufacture all kinds of bolts and ball screws. On the whole, the whirlwind technology is widely used in daily life, and we can keep improving the feature of the whirlwind machine, in that way, we can keep doing great in machinery.
