Important! Excavator Examination before Working

Chinese Spring Festival comes to an end, people starts to return to work. Some people may have a body examination before working in order to keep a good physical and mental condition to make an excellent performance in a new year. That is the same rule for the excavator, which needs to be carefully checked after being idle for a long time in order to create the maximum productivity. Generally, there are three steps to go for a careful examination.


First, examination should be made before starting the machine. Check the fuel oil level and discharge the waste and water from the fuel tank. Check the engine oil level and quality. Check the hydraulic oil level and quality. Check the reduction gears and coolant to avoid any cracks and leakage. Check the lubrication conditions of the joint parts, add the lubricant if necessary. Keep the crawler belt and bolts in joint parts tight. Ensure the meters show accurate data. Second, examination during operation, preheat the Indian excavator with the temperature below 3℃ for several minutes. Set the machine in idle running for 5 to 10 minutes with no load to make the hydraulic oil temperature reach 40℃. In the cold days, rotate the upper body of the machine to 90°, then hold up the crawler belt to make it rotate for several circles to cast off the dirt.


Finally, check the ambient. Safety signs should be set in the entrance and surrounding of the machine parking place to avoid any dangers. The parking ground should be hard, flat and spacious enough for evacuation under emergency circumstance. The comprehensive examination can inject power to the excavators to make it create the maximum productivity and reduce the construction risk to the minimum at the same time.

Wind Energy Provides Power for Netherland Trains


Netherland is known as the “hometown of tulip” and the “kingdom of windmill”, tulip and windmill are the marks of this beautiful country. As the treasure of Netherland, the wind resource once again is put into great use–providing energy for trains. All of the trains in Netherland are driven by electricity and several newly-built wind plants started to provide power for trains on the first day of 2017, which makes Netherland become the first country in the world that completes the goal of renewable energy providing power for trains.


Wind power is one of the main sources for electricity generation in Netherland. Using wind turbine generator to generate electricity is not only environmental-friendly but also can adjust one country’s energy structure and improve people’s life quality. Reducing carbon emission is not only Netherland’s wish but also the goal of the whole world, and Netherland has set a good example for the world in renewable energy development. Actually, 75% of Netherland trains were driven by wind power till last year, and the percentage reached 100% on January 1st of this year. The crawler cranes is an indispensable device when installing a wind mill.

The wind turbine generator appeared in the 1890s and developed fast since 1980s. In the past years, the diameter of the rotor blade kept increasing and the rated power kept improving, being more and more widely used in industrial applications. More and more countries in the world take deep interest in the wind resource development, which will make the wind power more popularized in the future.

Hydraulic Roller VS Mechanical Roller, which is the King of Road Machinery?

Road roller can be divided into hydraulic type and mechanical type. Discussions have been generated about the comparison of the two types in different aspects. The comparison mainly focuses on efficiency, safety, environmental protection, maintenance, price, reliability and comfort.

The mechanical roller has no front wheel drive and its working speed is fixed. The hydraulic one adopts full-wheel drive, which allocates more power to the vibrating drum, improving the compactness and reducing the compacting times, having more advantages in improving efficiency. And the hydraulic type needs no stop in the travelling process, improving 10% in efficiency than the traditional mechanical one. For safety, braking is an important factor that decides whether the machine can be stopped immediately once emergency happened. The brake of the hydraulic one combines with the joystick and can be locked when emergency happened. The brake and joystick of the mechanical one is separated, which may cost more time for the operator to stop the machine under urgent situation. Thus, the hydraulic roller has higher safety than the mechanical one, especially in mountainous area and dam construction. Also, the hydraulic type does a better job in heat dissipation than the mechanical one. The hydraulic type can be used in extreme temperature ranging from -40℃ to 60℃. And the hydraulic type is easier to be maintained.

Although the hydraulic roller has higher price than the mechanical one, its advantages in high efficiency, high reliability, environmental protection, safety and ease of maintenance are obvious. All of the industry experts, representatives and media believe that the hydraulic type has huge market potential in the future.
